Abstract
Decision-makers in cities have realized their pivotal role in addressing climate change, and
they are responding accordingly. This thesis presents three papers that explore the process
of responding to climate change in cities, highlighting the situation in selected global cities
with varying economies and development priorities. The methodology for conducting an
urban greenhouse gas inventory in three Chinese cities is detailed in the first paper,
illustrating issues of economic development and climate change mitigation in a transitional
economy. Next, the greenhouse gas emissions savings of various strategic mitigation plans
are quantified for Toronto, demonstrating the aggressive actions needed in developed cities
to approach carbon neutrality. The third paper explores issues associated with climate
change in three developing cities, emphasizing the need for synergic development
incorporating strategies for both mitigation and adaptation. The thesis concludes with an
overview of the importance of innovation and further research to future responses to
climate change.

Acknowledgments
It is hard to imagine that my past two years will be concluded with a single document, for
the experiences I have had cannot be fully expressed within the pages of this thesis. The
full value of my education was obtained beyond my courses and outside my graduate office:
the internship opportunities, the chances to travel, the seminars and presentations, and the
discussions and debates have shaped my perspective on sustainability in cities. It is for
these experiences that I am truly grateful.
My internship opportunities have been incredible learning experiences, and they have given
my research a unique, real-world advantage. Thank you to Zerofootprint, Edward Leman of
Chreod Inc., and the Urban Development Unit of the World Bank in Washington, DC for both
the research data support and the opportunities for professional development.
Thank you to my peers, the world-class Sustainable Infrastructure Group (SIG): Dave
Bristow, Sybil Derrible, Eugene Mohareb, Dave Rulff, Sheyda Saneinejad, Rob Stupka, and
Ryan Zizzo. It has been a pleasure to learn with you all, and I know we will remain
colleagues in the future.
Thank you to Dan Hoornweg and Murray Metcalfe, not only for their official roles as
internship supervisor and professor, but for their mentorship. Your wisdom, insight, and
encouragement will continue to inspire me as I enter the next phase of my career.
Most of all, thank you to Chris Kennedy for being an outstandingly supportive advisor. My
Masters experience was wonderful because of your encouragement and understanding.
Thank you for treating my compulsion to travel as an opportunity, not a complication; for
meeting my difficulty getting started with support and encouragement; and for humouring
me during the meetings when I just wanted to sit around and discuss ideas. You have
always maintained that my Masters could be whatever I wanted it to be, and it has
developed into an experience far greater than I could have ever imagined. Thank you.

Chapter 1 Introduction and Background
We are in an era of rapid change that will result in significant consequences for future
generations. The emergence of a new and heavily connected global economy has resulted in
business models based on cheap labour and cheap resources located beyond the confines of
national borders. We have realized the environmental impacts of our actions, such as a
changing global climate system, and we are increasingly experiencing the consequences.
Cities are positioned at the epicentre of this new reality. They are hubs of business and
commerce, heavy consumers of resources, and home to innovation and technological
development. People all over the world are flocking to cities to be a part of this global
phenomenon, in search of quality of life and opportunities that are not available anywhere
else. As a result, urbanization is occurring at unprecedented rates, and the majority of the
world’s population now lives in cities. The relationship between cities and climate change is
somewhat circular: the activities in cities are a chief cause of climate change, and cities will
be severely impacted by climate change. This complex relationship has prompted authors to
refer to cities as a “battleground for sustainability” (Clarke 2003). Cities are where the fight
against global climate change will be won or lost.
The traditional response to global problems is a globally coordinated effort by nations and
international agencies, such as the United Nations Framework Convention on Climate
Change (UNFCCC) and its Kyoto Protocol. However, the importance of locally oriented
solutions and actions is becoming more recognized. City leaders, such as those in the C40
and the Covenant of Mayors, have acknowledged that their local decisions will have global
impacts. Their cities no longer operate in isolation, but instead have an inherent
responsibility to respond locally to global issues. While nations may be the entities agreeing
to treaties and setting targets, cities are where these changes will occur – simply because
cities are where the majority of people live. The lifestyle, consumption habits, and everyday
choices of the urban resident have profound impacts on the global economy and the level of
greenhouse gas production. City leaders are recognizing that sustainability-motivated
changes to policy and infrastructure will have a direct impact on those choices.
In keeping a global perspective, it is important to acknowledge and understand the
variations between cities. The differing economies and political priorities in cities will
2
certainly play a role in a coordinated global effort against climate change. Challenges for a
city in a developing country will vary greatly from those a developed city. The true
opportunities will lie in the communication and dissemination between cities that is enabled
by our globalized networks.
This thesis presents three papers about global cities and their response to climate change.
Each paper highlights a different type of urban economy and a different developmental
priority. Through these papers, the thesis explores the response to climate change from the
perspective of a developed city, cities with transitional economies, and cities in developing
regions of the world. The variations also illustrate the progressive stages of local action on
global climate change. While responses undertaken by cities are diverse, when viewed
together they represent a holistic, global approach to one of our generation’s most pressing
issues.
The Response to Climate Change
Climate change is a complex problem. In many ways, it has the characteristics of what
Rittel and Webber (1973) coined a “wicked problem”; that is, climate change is a problem
that is not fully understood, there is not one correct solution, and attempts at solutions may
in fact cause further problems. The impacts of cities on global climate change, and, in turn,
the impacts of climate change on cities, are topics that have received significant attention in
the literature. The problems and the solutions are explored simultaneously: urban
infrastructure strategies for climate change mitigation and adaptation are developed and
piloted as the debate ensues about standardized methodologies for inventorying greenhouse
gas emissions. However, if the effectiveness of the action on climate change is to be
maximized, there is an increasing need for coordination and planning.
This thesis explores the response to climate change in cities as a process. The first step is
an understanding of the systems in a city; this includes, for example, knowledge of the level
of resource consumption, the amount of greenhouse gases produced by various sectors,
infrastructure vulnerabilities, and development priorities. Following a thorough assessment,
decision-makers are able to best target funds and resources into areas that will have the
largest impact. The mitigation and adaptation strategies presented are catered to the
circumstances of each city, but the most effective effort will require knowledge-sharing
between cities.

Understanding the Urban System
The phenomenon of urbanization has occurred throughout history, placing cities at the focal
point of nearly all civilizations. People have always followed their social instincts to group
together and rely on each other for survival, creating systems and processes to ease the
consistent demands of daily life. Similar to biological ecosystems, the services found in
cities are diverse and support the wide range of human requirements. Urban services meet
physiological and social needs while providing economic and civic opportunities that serve
the population. Resources are brought into the city for consumption and waste products are
expelled.
The different types of infrastructure in cities support the diverse aspects of urban life. The
physical infrastructure in cities provides the foundation for physiological survival: shelter
and mobility, as well as access to energy, water, and goods, allow time traditionally devoted
to life-sustaining activities, such as firewood or water collection, to be used for social and
economic pursuits. The social and economic infrastructures provided by individual urban
citizens are vital. Each urban participant has a role and contributes to the function of the
city; for example, the grocer brings in food, the bus driver enables mobility, the factory
worker manufactures goods, and the business professional supports economic growth and
monetary flow. The economic and civic infrastructures in cities support localized decision-
making and, in democratic states, provide a feedback mechanism that allows urban citizens
to influence the form and function of their cities.
Viewing the city as an ecosystem allows for the application of the concept of metabolism: a
representation of the inflows and outflows of the urban system. Numerous authors are
exploring urban metabolism as a method to understand the global impacts of cities (for
example: Kennedy et al. 2007; Zhang, et al. 2009.), including the resource and material
demands of the city, as well as the waste and by-products. For example, Figure 7 in Chapter
4 shows an urban metabolism diagram for the city of Amman. Energy and water resources
enter various sectors of the urban system, and solid waste and greenhouse gas (GHG)
emissions are produced. In a discussion of the climate change impacts of cities, urban
metabolism is particularly relevant: in viewing the city as an open system interacting with
the outside world, the GHG emissions that are attributed to cities become increasingly
apparent (Kennedy et al. 2009b; Kennedy et al. 2010).
Local-scale GHG emissions inventories have been pursued for nearly 20 years. One of the
first organizations to undertake city-level GHG emissions reporting was the International
4
Council for Local Environment Initiatives (ICLEI) – now known as ICLEI-Local Governments
for Sustainability. As part of the ‘Local Agenda 21’ efforts in 1992 (United Nations 1992),
ICLEI initiated a campaign to quantify and reduce GHG emissions in cities. At this time,
issues of boundary, emissions allocation, and methodological consistency across cities were
topics of discussion in the academic literature (see Harvey 1993, Kates et al. 1998). Over
the past ten years, the number of organizations producing GHG inventories for cities has
increased, and methodological issues continue to be discussed (see Bader and Bleischwitz
2009; Kennedy et al. 2009a).
Today, a prominent complication associated with conducting an urban greenhouse gas
inventory is still the issue of emissions attribution. The GHG emissions inventories for
nations assign any emissions that occur within the jurisdictional borders of a country as that
country’s responsibility (IPCC 2006). However, such an approach is not possible for cities
given their heavy reliance on resource and material flow from outside their boundaries. In
fact, the interconnected nature of the global economy makes this strategy debatable for
countries as well: calculations using IPCC methodology neglect cruising emissions from
international flights, and the majority of emissions produced to manufacture goods
consumed in rich countries do not take place within their borders (see Davis and Caldeira
2010).
The attribution of emissions may be classified as either “production” or “consumption” (see
Kennedy et al. 2009a): emissions are either directly produced within the jurisdictional
boundary or they are a result of consumption activities taking place within the boundary.
The IPCC (2006) inventory methodology for nations is strictly based on production. The
WRI/WBCSD GHG Protocol (WRI/WBCSD 2004) is designed for corporate and institutional
reporting and separates emissions attribution into “scopes” that cover production and
consumption (Table 1). Recently, a harmonized standard for urban emissions inventories
was proposed by UNEP, UN-HABITAT, and the World Bank: the International Standard for
Determining GHGs from Cities (UNEP et al. 2010; followed in Appendices A-F) is based on
the methodological discussion of Kennedy et al. (2009a).
The International Standard is an emissions reporting guideline, and it requires a hybrid of
production and consumption inventories. It includes emissions produced in the city, such as
those from fossil fuel combustion, industrial processes, and agriculture and land-use
(AFOLU). It also includes emissions that would not be produced if not for activity in the city;
for example, emissions from electricity generated outside the city boundaries but consumed
inside the city; emissions from the decomposition of waste produced in the city; and

emissions from aviation and marine vessels resulting from the economic activity of the city.
Though the overall inventory philosophy varies from that of nations, the methodology of the
IPCC (2006) is followed for calculations in each specific sector.
A city’s greenhouse gas inventory is particularly valuable as the first step in a city’s
response to climate change. The inventory serves as an indicator of particularly emissions-
intensive sectors, as well as providing verifiable metrics upon which to facilitate targeted
project financing. As further actions on climate change are taken, methodologically
consistent greenhouse gas inventories can indicate if the actions are reducing emissions as
expected, or if their impacts are negated by unforeseen circumstances. An inventory that
reveals few emissions may also point to areas of greater concern to the city, such as the
need for low-carbon development of services or adaptation to climate change.
Strategies for Mitigation
The technology exists for carbon-neutral cities; however, the capital costs are high, and the
way of life for some wealthy urban residents will be fundamentally challenged – especially in
North America. The infrastructure options that reduce greenhouse gas emissions are diverse
and cover a variety of sectors, including buildings, transportation, energy, waste, and other
municipal services (see Kennedy 2010; Lebel et al. 2007). Policy and governance also plays
6
an important role: Bai and colleagues have shown that vertical linkages are essential for the
down-scaling of policy and up-scaling of pilot projects (Bai et al. 2009; Bai et al. 2010).
Perhaps most importantly, the fundamental strategy for climate change mitigation in cities
is support from governments and citizens.
The greenhouse gas emissions saved by mitigation strategies require verification. Various
climate change scenarios will be simulated during the development of a city’s strategic
mitigation plans, often with models or software (for examples, see Lin et al. 2010; Li et al.
2010; Kennedy 2010). One of the benefits of approaching climate change quantitatively by
conducting an inventory and testing a strategic GHG reduction plan is that high impact
projects are favoured. It is important to assess whether the adopted mitigation strategies
will meet emissions targets and result in emissions reductions on a global scale.
Strategies for Adaptation
Cities are particularly at risk when it comes to the management of extreme events. To give
context, some authors point to the aftermath of Hurricane Katrina as an example of the ill-
preparedness of cities in coping with weather disasters (Susskind 2010; Simon 2010). The
comparison gives a dire image as to the realities of how climate change will impact cities
that are not equipped to cope.
The best strategies for how to adapt to climate change vary with each city. Similar to a
greenhouse gas inventory, adaptation planning is best preceded by an analysis: specifically,
an urban climate change risk assessment. While quantitative climate change risk
assessments are beyond the scope of this thesis, two models available include the UCCRN
(Urban Climate Change Research Network) “Framework for City Climate Risk Assessment”
(Mehrotra et al., 2009) and the PIEVC (Public Infrastructure Engineering Vulnerability
Committee) “Engineering Protocol for Climate Change Infrastructure Vulnerability
Assessment” (PIEVC, 2008). However, a quick overview of the geographic and social
circumstances of a city can usually point to areas of greatest concern. For example: a
coastal city may be at risk for sea-level rise; a city lacking water drainage infrastructure
may be risk for extreme flooding; and a city in a desert may face water shortages.
The most important adaptive approach for cities is that of resilience; that is, ensuring
infrastructure and urban systems are able to cope with extreme events. Redundancy and
elasticity are key components of resiliency. Implementing systems that can cope with
change, creating backup systems that can replace failed ones, and targeting infrastructure
7
and populations that are in harms way are characteristics of resilient urban planning.
Unfortunately, the lack of reliable infrastructure, limited access to resources, and saturated
social systems make cities in developing countries the least resilient in the world.
There are numerous adaptation strategies for cities that address vulnerabilities in a variety
of urban sectors. Strengthening sea-walls, rehabilitating mangroves, and improving storm
water drainage address vulnerabilities associated with sea-level rise and flooding. Enhancing
buildings, physical infrastructure, health services, and urban greenery help alleviate issues
with extreme precipitation and heat event. Diversification of energy and water resources
ensures availability during disruptions. The specific portfolio of adaptive strategies will
depend on the specific needs of the city.
The Mitigation-Adaptation Nexus
The key to an effective climate change response requires strategies that address both
mitigation and adaptation. Mitigation and adaptation are complementary: they address
climate change from complementary geographic and temporal scales (Figure 2). The
benefits of mitigation are global, while the benefits of adaptation are local; the impacts of
mitigation action are long-term, while impacts of adaptation are immediate. Therefore, if
properly executed, mitigation strategies will keep climate change at a level that is
manageable by adaptive strategies.
Themes and Organization
The three papers presented in this thesis each highlight a different type of economy, a
different development priority, and a different stage in the climate change response
process.
The first paper illustrates the perspective of urban China: one of the fastest urbanizing
countries in the world. As the economy transitions, top priorities are economic growth,
improved quality of life, and, more recently, environmental preservation. The paper
presents detailed greenhouse gas emission inventories for Shanghai, Beijing, and Tianjin
using the new International Standard, and it highlights actions local and national
governments are taking to reduce emissions. The paper represents the first stage in the
climate change response: thorough and standardized emissions inventorying. It points to
the importance of standardized calculation, global perspectives, communication, and
governance to climate change action.

The second paper focuses on Canada; specifically, it presents a strategic low-carbon
infrastructure plan for Toronto. In Toronto’s developed economy and mature urban context,
greenhouse gas mitigation is the top development priority. Three scenarios are quantified
using the Getting to Carbon Neutral model (Kennedy 2010): a 2004 baseline; a projection
to 2031 based on currently planned government policies; and a projection to 2031 based on
a more aggressive action plan. By quantifying an aggressive mitigation response to climate
change, the paper highlights that current policies will be ineffective at producing the
emissions reductions needed for global-scale impacts.
Finally, the third paper explores the climate change response in three diverse cities:
Amman, Jakarta, and Dar es Salaam. Though an exploration of the emissions inventories
and urban systems, it becomes apparent that adaptation and resiliency are the most
necessary responses to climate change in these cities. Their economies are still developing,
and the basic provision of services is the top development priority. The paper emphasizes
that the developing regions’ responses to climate change are complex: data is scarce, the
poor are most vulnerable to impacts of climate change (though they did not cause it), and
there are few resources for strategic planning. In these cities, the truly global nature of
climate change is revealed.
9
Building up these three papers, the thesis concludes with an overall discussion of some of
the broad issues raised, including: how to facilitate dissemination and mutual learning
between globally diverse cities; the scales of strategic response; and the importance of
funding mechanisms. Concluding thoughts and suggestions for further work are also
presented.

Chapter 2 Greenhouse Gas Emissions from Chinese Cities
Introduction
The world is becoming increasingly urbanized, and the trend of urban migration is most
pronounced in countries with transitional economies. China, in particular, has experienced
rapid urbanization, with its urban population increasing from 34% to 43% in just 10 years
(World Development Indicators 2009). The environmental consequences of China’s rapidly
growing urban economy are significant, particularly related to greenhouse gas (GHG)
emissions and climate change. Cities are at the epicenter of the country’s economic growth,
and, consequently, they are responsible for the majority of emissions.
The patterns of urban growth in China are unique and highly resource intensive. The shift
from a legacy of central planning to growth driven by the private sector and foreign
investment has resulted in multiple satellite cities and rapidly expanding urban centres that
envelop hinterlands (Seto and Fragkias 2005). Not only are farmlands disappearing, the
resource burden associated with the construction of buildings and infrastructure is high.
Annually for the past ten years, China has built nearly half of all new buildings in the world
by volume, the majority of which are residential and commercial buildings that require the
highest quantity of material resources (Fernandez 2007).
The energy intensity, and therefore carbon intensity, of economic growth varies from city to
city in China. Dhakal (2009) observed varying energy-economy pathways. Highly energy-
intensive cities are found mostly in the central and western parts of China. They are home
to energy-intensive industries and many of these inland cities require more space-heating
due to a colder climate. In contrast, lower energy-intensive cities are on the climatically
moderate east coast with a stronger service industry. While there is a difference in both
cases of energy-economy, it is important to note that the energy systems, urban activity
and infrastructure in both cases are conducive to high GHG emissions.
Research to date exploring GHG emissions from Chinese cities has focused primarily on
energy-related emissions. Dhakal (2009) has explored the energy intensity of urban areas
in China, particularly the policy implications of rapid economic growth and energy-related
GHG emissions. In addition to estimating annual energy-related GHG emissions in Shanghai,
13
Li et al. (2010) quantified future projections of GHG emissions to 2020 under business-as-
usual and basic-policy scenarios. At the household scale, the energy consumption and GHG
emissions of residential homes in Chinese cities have been investigated (Zheng et al. 2009).
The importance of this research is significant to policy development: given the energy-
intensity of the growing Chinese economy, as well as the reliance on fossil fuels, emissions
from energy consumption are highly relevant to development.
Intensive energy consumption is not however the only by-product of a rapidly developing
economy: emissions from waste and industrial processes are also important to consider.
The existing literature on GHG emissions from Chinese cities has not fully explored these
additional emissions sources. Accordingly, the objective of this work is to provide a more
comprehensive and explicitly detailed emissions inventory methodology for three Chinese
cities, including previously unconsidered sources of emissions, that is in line with new
international GHG inventory standards and practices.
This paper explores multiple aspects of the urban GHG inventory for the Chinese cities of
Shanghai, Beijing, and Tianjin (city characteristics shown in Table 2). An inventory
methodology for Chinese cities is presented that is consistent with both the format of
Chinese statistical data and the recently released International Standard for Determining
Greenhouse Gas Emissions from Cities (UNEP et al. 2010). The GHG inventory results for
the three Chinese cities are then compared with other global cities and their significance on
a global scale is discussed.
Calculating GHG Emissions from Chinese Cities
The first step towards reduction of GHG emissions is transparent and robust quantification.
GHG inventories should be conducted regularly, so as to track progress and indicate areas
for improvement. Regular reporting of emissions requires two important components: a
standard inventory methodology and up-to-date activity data. In the case of Chinese cities,
the latter is readily available and robust due to China’s thorough statistical collection.
However, as is the case with many global cities, the methodology for estimating and
attributing emissions has varied in past research.
The International Standard for Determining Greenhouse Gas Emissions from Cities (UNEP et
al. 2010) was released jointly by UNEP, UN-HABITAT, and the World Bank at the 2010
World Urban Forum in Rio de Janeiro in response to the increasing need for a harmonized
GHG standard for cities. Harmonization of GHG inventory methodologies have been

successfully adopted at the national, institutional, and project levels. For city-level
emissions, the number of organizations producing GHG inventories has increased in recent
years, and methodological issues are continually discussed in the literature (summarized by
Kennedy et al. 2009a). A recent study comparing six local-scale inventory tools (Bader and
Bleischwitz 2009) concluded that interoperability requires the adoption of a reporting
standard that rectifies issues such as emissions sources, sector definitions, and
measurement scope.
The GHG Standard is characterized by standard reporting tables, displaying emissions by
both sector and fuel or activity type. In-boundary emissions are reported from energy
(stationary and mobile combustion), industrial processes and product use, waste, and
agriculture, forestry, and other land use (AFOLU; however, they are not included in this
study). Out-of-boundary emissions are also reported from the generation of electricity and
district heating consumed in the city (including transmission and distribution losses),
aviation and marine vessels carrying passengers and freight away from the city, and waste
generated in the city. Emissions embodied in food, water, fuels, and building materials are
encouraged to be reported as additional information items. Consistency with sector-level
calculation methodology developed by the Intergovernmental Panel on Climate Change
(IPCC) is required.
There are several benefits of standardized reporting of emissions from cities. The GHG
Standard supports urban policy and improves access to finances for city projects.
Standardized reporting allows cities to create a GHG baseline from which to evaluate
subsequent emissions inventories. The opportunity for cities to learn from one another and
disseminate best practices is enhanced by a harmonized reporting standard.
Greenhouse gas emissions are generally calculated as follows:
15
FactorEmissionDataActivityEmissionsGHG ×= (1)
Activity data varies with each of the inventory components; for example, it may refer to the
consumption of energy or production of waste. In calculations for cities, activity data is
specific to the city while emission factors are often based on national values or IPCC
defaults. For the Chinese cities presented, the data was available to determine city-specific
emission factors for electricity and district heating, while IPCC defaults were used for other
emission factors, similar to Dhakal (2009).
Emissions from Energy
Every year, the Chinese Energy Statistical Yearbook (CESY) reports the energy
consumption, production, import, and export for all the provinces, including energy balance
tables reported in the style of the International Energy Agency (IEA). Shanghai, Beijing, and
Tianjin are provincial-level municipalities in China, whereby they are governed by a local
municipal authority reporting directly to the State Council. Energy statistics, and IEA-style
energy balance tables, are available annually for all three municipalities, providing essential
data for GHG emissions calculations.
Interesting patterns emerge when the energy balance tables are viewed through the lens of
urban metabolism (Kennedy et al. 2007; Zhang et al. 2009). Fuels can be tracked from
their entry into the provincial energy system through to their consumption. For example,
Table 3 shows part of the 2006 energy balance table for Shanghai (CESY 2007), highlighting
three fuels: “coal cleaned”, “coke”, and “coke oven gas”. The entry of the fuel into the
province, its transformation into other fuels or electricity, and its consumption by sector can
be tracked in the table. In the case of “coal cleaned”, the fuel enters the province via
interprovincial import, a portion is consumed by industry for energy and the majority is
transformed into “coke” and “coke oven gas”. The “coke oven gas” is used primarily for
industrial energy, with a portion transformed into electricity in thermal power processes.
Following on in the energy balance table (beyond what is shown in Table 3), the
consumption of the electricity can be tracked further by sector.
The energy balance tables explicitly provide the quantities of fuels entering the
transformation processes “thermal power” and “heating supply”, which were used to
determine the GHG intensities of electricity and steam heating respectively. For additional
emissions from stationary combustion, the total consumption of each fuel type was

Emissions from mobile combustion were taken to consist of all emissions from gasoline
consumption, diesel consumption, and kerosene and fuel oil consumed by the transportation
sector (with jet kerosene and marine fuel oil emission factors). To capture jet fuel and
marine fuel oil loaded onto vessels carrying passengers and freight away from the city, as
indicated in the GHG standard, fuel imported from “Chinese vessels refueling abroad” was

subtracted from consumption totals and fuel exported from “foreign vessels refueling in
China” was re-added.
Emissions from Industrial Processes
Industrial process emissions are non-combustion emissions released as a consequence of a
chemical process. Therefore, the amount of GHG emissions released can be determined by
multiplying the quantity of product by the production-based emission factor, as follows:
processproductindustry EFMGHG ×= (2)
where Mproduct is the mass the product and EFprocess is the emission factor of the process.
Chinese cities have heavy industrial activity, with emissions resulting from the mineral,
metal, chemical, and electronics industries. Emissions from the cement and steel industries
were quantified in this study, as China is the leading producer of cement and crude steel
globally (Fernandez 2007). The cement and steel industries located in the three cities were
found to produce significantly high amounts of GHG emissions, which were on par with
18
emissions from other sectors in the cities. The masses of cement and steel produced
annually are recorded as industry statistics (CSY 2007). These values were multiplied by
IPCC (2006) default production-based emission factors for cement (based on 60% clinker
content) and steel.
Emissions from Waste
The IPCC (2006) recommends the use of the First Order Decay methodology for calculating
waste emissions; however, it requires time-series data spanning 20 or more years, which is
usually not available for cities. As an alternative, Kennedy et al. (2010) used a pragmatic
adaptation of the IPCC (1996) Total Yield Gas approach. The Total Yield Gas method
estimates the GHG emissions that will be released over many years from the waste
produced in the inventory year, as opposed to the emissions released from waste
decomposition during the inventory year alone.
The mass of waste produced is combined with the emission factor specific to the disposal
method (landfill, incineration, etc.). The emission factor depends on the composition, and
degradable organic carbon content, of the waste. For example, the calculations for GHG
emissions from landfills are made as follows:
)1(21 0 reclandfilllandfill fLMGHG −⋅⋅= (3)
where Mlandfill is the mass of waste sent to landfill in the inventory year, L0 is the methane
generation potential, 21 represents the 100-year global warming potential for methane, and
frec is the fraction of methane recovered. The methane generation potential, L0, is calculated
as follows:
FDOCDOCMCFL F ⋅⋅⋅⋅=12
160 (4)
where MCF is the methane correction factor (1.0 for managed landfills), DOC is the
degradable organic carbon (calculated as ∑ ⋅i
ii fW , with Wi representing IPCC default waste
weightings associated with each waste category fraction, fi), DOCF is the fraction DOC
dissimilated (assumed to be 0.6), F is the fraction of methane in landfill gas (assumed to be
0.5), and 16/12 is the stoichiometric ratio between methane and carbon.
19
Chinese waste statistics are available for all provinces, and therefore they are available for
Shanghai, Beijing, and Tianjin (CSY 2007). The mass of waste is reported by disposal
method, including landfill, compost, and incineration. The IPCC (2006) default waste
composition values for East Asia were used to estimate the emission factor, and it was
assumed that equipment for methane capture was not installed at landfill sites.
Results of Chinese Cities
A summary of the GHG emissions for Shanghai, Beijing, and Tianjin are shown in Table 5
(full standard reporting tables are shown in Appendices A-C). All three cities are all heavy
GHG emitters: in total, Shanghai, Beijing, and Tianjin emitted 12.9 tCO2e per capita, 10.8
tCO2e per capita, and 12.2 tCO2e per capita respectively in 2006. The distribution of
emissions by sector is similar for all cities; as an example, the emissions distribution for
Shanghai is shown in Figure 2. Emissions were primarily due to electricity consumption and
heating and industrial energy use, followed by the transportation sector. The GHG
inventories reveal some important physical and socioeconomic characteristics of the three
cities studied.
Like many Chinese cities, Shanghai, Beijing, and Tianjin rely primarily on coal for power
production. The share of coal in thermal power generation is exceptionally high (87% in
Shanghai, 86% in Beijing, and 98% in Tianjin), making the GHG intensity of power
production higher than other global cities (see Figure 6). As illustrated by the local
electricity production mixes and emission factors shown in Table 6, a switch from coal-
power would have a significant impact on reducing GHG emissions.
A closer look at emissions produced from residential heating and industrial activity reveal
some interesting differences between the three cities. In general, coal combustion is
prevalent: a portion of stationary combustion in the cities is from steam produced in district
heating facilities. The largest production share of the steam heat is from coal, and the
majority of it is used by industry. However, the partitioning of other energy by stationary
combustion varies. Industrial energy emissions per capita are highest in Shanghai and
Tianjin, while residential energy emissions per capita are highest in Beijing. Differences in
climate, quality of life, and type and scale of industrial activities can explain these patterns.
Non-energy emissions from industrial processes also provide insight into the variation in
industrial activity. Shanghai is the largest producer of steel (~19 Mt) and Beijing is the
largest producer of cement (~12 Mt); accordingly, Shanghai has the highest industrial

emissions per capita from the metal industry and Beijing from the mineral industry. Tianjin
has significant steel production as well, putting its industrial emissions per capita from the
metal industry close behind those of Shanghai.
Emissions from the transportation sector are high for all cities, particularly the amount of
emissions from road transportation. In this sector, the cities are distinguished by the level
of emissions from aviation and marine activity. Shanghai’s per capita emissions from
aviation and marine are highest of the three cities, indicating that it is the most active hub
of international economic activity and trade. Beijing’s busy international airport is reflected
in its high level of aviation emissions, while Tianjin’s marine activity is more GHG intensive
than its aviation activity.
Lastly, the waste management practices in the three cities impact their GHG emissions. The
method of waste treatment varies by city: the majority of Shanghai’s waste is incinerated,
while waste in Beijing and Tianjin is primarily sent to landfill. Beijing’s waste emissions are
significantly higher than the other cities, reflecting a higher amount of waste disposed.
Waste that is incinerated or composted produces fewer emissions, contributing to the low
waste emissions per capita for Shanghai.
Comparison to Global Cities
GHG baselines are interesting indicators of physical and economic urban structure.
Greenhouse gases are, in essence, waste products. The level of economic and social
activity, as well as the systems and structures that enable the activities, inform the amount
of greenhouse gases produced. For example, a city with heavy industry, high car usage, and
coal-generated electricity will have higher per-capita emissions than a city with a
knowledge-based industry, expansive public transit, and nuclear power production. These
differences between cities, as well as changes through time as a city develops, are captured
by comparing GHG baselines.
Compared to the ten global cities studied by Kennedy et al. (2009b), Shanghai, Beijing, and
Tianjin are among the highest per-capita emitters (Figure 3). The bulk of the emissions are
produced by the electricity, heating and industrial sectors, largely due to the predominately
coal-based energy structure. The level of ground transportation emissions is comparable to
developed cities with extensive public transit networks, such as London or Barcelona. The
heavy manufacturing and industrial base of the economy in Chinese cities is reflected in the
large portion of industrial process emissions.

As shown in Figure 4, heating and industrial energy consumption for all global cities is
closely related to climate; however, some cities have energy consumption exceeding that
expected from the correlation to heating degree-days. This is likely representative of an
active industrial sector. Shanghai, in particular, falls well above the correlation trendline due
to its extensive industrial energy consumption.
The emissions from transportation are indicative of urban form: Figure 5 shows an inversely
proportional relationship between transportation emissions and population density. As
described in Kennedy et al. (2009b), North American cities tend to be spread out, resulting
in heavy reliance on the automobile and, hence, high transport-related emissions. In
contrast, the three Chinese cities are densely populated with low transport emissions. The
Chinese cities have transportation emissions comparable to European cities with extensive
public transport networks. This is potentially good news for Chinese cities: if they can
maintain density as they grow, per-capita transport emissions will likely remain constant.

One of the biggest areas of variability among the cities is the GHG intensity of electricity
production. Figure 6 shows the electricity consumption, electricity emissions, and electricity
emissions factor for the Chinese cities and 10 global cities. While they may not have the
most electricity emissions or the highest level of electricity consumption, the Chinese cities,
along with Cape Town, have the most GHG-intensive methods of electricity production. The
high emission factors reflect the heavy reliance on coal for electricity production, and it
raises concerns about how Chinese cities will mitigate the GHG impacts of future heightened
electricity demands.
In addition to a comparison to other global cities, the total amount of GHG emissions
attributed to Chinese cities is so high that it is comparable to nations. When compared to
the GHG emissions (excluding forestry and land use changes) reported to the United

Nations Framework Convention on Climate Change (UNFCCC) by countries, Shanghai ranks
25th (Hoornweg et al. 2010). Shanghai is producing more emissions than many countries,
including Thailand, the Netherlands, Venezuela, and Saudi Arabia. This reality makes it
important to consider that action to reduce GHG emissions is just as necessary at a city-
level as it is at a national level.
Discussion
The results of this study, as well as recent research in the area, point to some important
issues arising in China. There is great potential in Chinese cities for sustainable change and
27
progressive policy, and cities are already showing leadership in this area. This study
indicates that the primary sector to target for reducing emissions in Chinese cities is energy,
which is supported by resource potential and government support. However, this is not
without certain barriers to take into consideration.
The GHG emissions inventories for Shanghai, Beijing, and Tianjin highlight specific areas to
be addressed in mitigation plans; the most significant of which is the reliance on coal for
energy. The GHG intensities of electricity production in Chinese cities are among the highest
in the world. Therefore, emissions will increase with increasing electricity consumption at a
steeper rate than other cities. A shift away from coal to renewable technologies will be a
powerful step in GHG reduction.
The opportunities for renewable energy in China are strong. There exists a tremendous
potential capacity for hydro, wind, and solar power, as well as strong policies that will
increase the share of renewables and drive technological development (Cherni and Kentish
2007; Feller 2006). Li et al. (2010) describe how Shanghai, in particular, has concrete plans
to spur the development of wind and solar energy sources and reduce the share of coal
used for electricity generation. Aggressive policy actions, such as adoption of solar
integrated building construction, biogas power generation, and improved urban waste
disposal, are on the agenda for many cities in China.
A significant factor contributing to the move towards sustainability in China is buy-in by the
national and local governments. China has recognized the need for reducing the GHG
intensity of their economic growth, and they have set specific goals to do so in the 11th 5-
year plan. The target is to reduce the energy consumption per unit GDP by 20%, which will
have significant impacts on emissions reduction (Li et al. 2010). In an analysis of 30 best
sustainable urban practices in Asia, Bai et al. (2010) have demonstrated that political will is
essential for the success and scaling of pilot projects. The political will demonstrated in
China will prove to be a driving factor towards action on climate change.
However, there are important barriers to consider that may jeopardize the adoption of
sustainable practices in China. Issues of governance and emissions relocation are
particularly relevant. At the local level, issues with down-scaled governance and the central
government’s control over the enforcement of local environmental policy are issues in
Chinese cities (Bai et al. 2009). From the perspective of city officials, unprecedented
environmental actions, such as aggressive reduction targets, are also undesirable as they
may undermine national level policy (Bai 2007). Given the demonstrated governance
28
barriers, it becomes increasingly necessary for communication and dissemination to take
place between local and national governments.
If urban emissions are considered in isolation, the issue of emissions relocation becomes
prevalent. Frequently, urban air quality is preserved by moving emissions-producing
factories and enterprises out of the city: to other cities, suburbs, or rural areas. This has
been observed in China, as some environmental improvements in Chinese cities are due to
the relocation of pollutant sources (Bai et al. 2009). While this may improve local air quality
and emissions inventories, it results in consistent, or worsened, levels of emissions on larger
scales.
The issue of emissions relocation may also be considered on a global level. When comparing
emissions from the global cities in Figure 3, it is interesting to reflect on the nature of the
global economy. Many of the products consumed in the low-emitting European cities are
produced in the high-emitting Chinese cities. It becomes relevant to question who should be
allocated responsibility for the emissions released during the production of exported goods
(see Dodman 2009). A recent study by Davis and Caldeira (2010) found that 22.5% of
emissions produced in China were “exported” to consumers abroad. Developed countries
have, in essence, relocated the emissions associated with the production of their goods to
China. While many of the emissions resulting from manufacturing and industrial activity are
“exported” abroad, China receives the economic benefit. Chinese cities have the highest
GHG emissions per unit GDP of all cities in the world (Hoornweg et al. 2010). There is an
enormous need, and potential economic opportunity, for Chinese cities to mitigate their
emissions while continuing to maintain their GDP growth.
The level of China’s urban greenhouse gas emissions is changing rapidly over time. The
urban population is increasing at unprecedented rates, and the economy is flourishing. As
China grows, urbanizes, and secures its position as a powerful player on the global stage, it
is important for the country to adopt the global standard for reporting GHG emissions from
its cities. Chinese cities are global participants in the urban drive for emissions reduction,
which requires accurate, up-to-date GHG inventories. With the increasing collaboration
between city mayors and officials, new leadership has emerged in the arena of climate
change mitigation, and China will undoubtedly play an important role.

Chapter 3 A Low-Carbon Infrastructure Plan for Toronto, Canada
Getting to Carbon Neutral: A Guide for Canadian
Municipalities
Together with the Toronto and Region Conservation Authority, the Sustainable
Infrastructure Group at the University of Toronto has developed a strategic planning tool for
Canadian municipalities. Getting to Carbon Neutral (Kennedy 2010) outlines best practices
in sustainable infrastructure throughout the world, and it offers policy and technology
strategies to apply in Canadian municipalities. To assist with the decision-making process,
the guide gives an overview of how to conduct a greenhouse gas (GHG) emissions inventory
for a municipality, as well as quick ‘Estimation Guidelines’ of resultant GHG emissions
savings for each strategy. The strategies focus on four sectors: buildings, transportation,
energy supply, and municipal services (Table 7).
The potential for carbon savings in the building sector is very large, given that the operation
of buildings account for up to 40% of GHG emissions in cities (UNEP and UNEP SBCI 2009).
Efficient electricity use and advanced building envelopes can be combined with renewable
energy technologies to make a building operationally carbon neutral, even in Canada.
Strong incentives for building retrofits and sustainable building design are needed to make
this possible on a city scale.
In the transportation sector, a focus on public and active transportation is needed. Use of
private automobiles needs to be reduced and replaced with alternative fuels and vehicle
technologies. Behaviour change will require strong financial incentives, as well as
appropriate infrastructure to make the change conductive to a high quality of life.
Reducing the carbon intensity of the energy sector requires collaboration at all levels of
government. Renewable electricity generation lowers the greenhouse gas intensity of the
regional electricity grid. For heating and cooling of buildings, community-based energy
technologies, such as district heating and underground thermal energy storage, reduce or
replace the need for fossil fuel combustion. While some technologies are capital intensive,
energy savings are significant and have proven effective in cities throughout the world.

Cities have direct control over municipal sector operations, including waste treatment and
urban forestry. Advanced waste sorting is cost effective and easy to implement, and
methane capture at landfill sites can reduce GHG emissions and improve air quality.
Enhancing the urban canopy not only sequesters carbon dioxide, but also helps moderate
the urban climate and reduces air conditioning requirements.
Community Scale Low-Carbon Developments
Best practices in sustainable infrastructure design have reduced GHG emissions for cities in
Canada and abroad. While specific projects have demonstrated success, achieving carbon
neutrality, or near-neutrality, requires a synergetic approach where a variety of GHG
reduction strategies are employed. This is currently demonstrated at the community scale in
three notable projects: Dockside Green in Victoria, B.C. (Box 1); Beddington Zero-Energy
Development (BedZED) in London, U.K. (Box 2); and Vauban District in Freiberg, Germany
(Box 3). All three have advanced energy efficient homes and combined heat and power
facilities. Dockside Green has online smart-metering and energy controls, BedZED homes
are heated and ventilated using passive solar techniques, and Vauban is parking-free and
pedestrian focused. The combination of numerous GHG reduction strategies has brought
these developments close to carbon neutral.
Moreover, the potential for carbon neutrality extends beyond the community scale to the
city scale, demonstrated by the planned development of Dongtan Eco-City near Shanghai,
China (Box 4). The proposed city is designed to be carbon neutral (at least with respect to
direct emissions) with advanced energy efficient homes, emission-free transportation
technology, renewable electrical generation, and combined heat and power facilities.
The GHG reduction strategies described in Getting to Carbon Neutral have already proved to
be effective in new community and city developments throughout the world. The strategies
will also make significant impacts when applied to existing cities in Canada. In this paper,
example calculations are conducted for the City of Toronto, highlighting the potential of
various combinations of reduction strategies.
Integration of Strategies: Toronto Case Study
The Toronto Case Study is divided into three scenarios: a 2004 Base-Case Scenario; a 2031
Planned-Policies Scenario; and a 2031 Aggressive-Alternatives Scenario. The 2004 Base-
Case Scenario based on current municipal infrastructure and demographics, and it is verified
with respect to values presented in the City of Toronto’s 2004 GHG Inventory (ICF

Box 1: Dockside Green, Victoria, British Columbia
Dockside Green is a 15-acre mixed-use community developed on a brownfield site near
downtown Victoria, BC, featuring a range of low carbon strategies. Buildings are designed to
be LEED® Platinum certified and 45-55% more efficient than buildings designed to current
national codes. This is achieved by heavy insulation, double-glazed low-e windows, heat
recovery ventilators, and external shading on south and west windows to minimize heat
gains. Electricity demands are reduced through use of Energy-Star appliances, low-energy
lighting with occupancy sensors, and day-lighting techniques. Energy use will be smart-
metered with digital controls accessible over the internet. Heat and some electricity will be
provided by a biomass energy cogeneration facility with peak heating needs met with
backup natural gas boilers. The community is designed to be pedestrian friendly with
abundant green spaces and walkways, as well as reduce transport emissions with a mini-
transit system and car share program. Compared to a traditional development, 5,215 tCO2e
per year are avoided through biomass use, space heating efficiency, and electricity
efficiency.

Box 2: Beddington Zero-Energy Development (BedZED), London, UK
BedZED, short for Beddington Zero-Energy Development, is a high density, mixed use,
carbon-neutral community developed on an urban brownfield site in Southwest London
completed in 2002. The community is designed to maximize social amenity and
environmental sustainability while maintaining financial effectiveness. All buildings have
advanced envelope insulation and air-tightness, and all heating, cooling, and ventilation is
achieved using passive techniques (including terraced blocks, building orientation that best
utilizes solar gains, and heat recovery wind cowls). The absence of mechanical systems
reduces electricity demand, as do smart meters, low energy appliances and light bulbs.
Electricity and additional heat is supplied from a bio-fuelled combined heat and power plant
(CHP), which runs on wood chips from local urban tree trimmings. Photovoltaic cells on
southern facades also generate electricity.

Box 3: Vauban District of Freiberg, Germany
Vauban is a city district of Freiberg, Germany developed using co-operative and
participatory planning strategies. All buildings comply with low energy standards, some of
which are passive houses or plus energy houses. A co-generation facility and over 450m2 of
solar collectors provide 45% of the community’s electricity requirements as well as district
heating. The community is “parking-free”, and close to half of the households are car-free.
Doorstep parking is replaced by a peripheral community car park, which also stores
community car sharing vehicles. Cars are permitted on residential streets for pick-up and
delivery purposes only, where they must travel at “walking speed” (5 km/h). Businesses,
schools, shopping and recreation facilities are all located within walking or cycling distance.
Public buses and tram lines connect Vauban to the Freiberg city centre. The community
design is estimated to save 28 GJ of energy and 2100 tCO2e per year.

Box 4: Dongtan Eco-City, Chongming Dao, China
Dongtan Eco-City is planned for development of the south-east end of Chongming Island
near Shanghai. Forty percent of the land area will be urbanized, leaving space for organic
agriculture and existing wetlands. All housing will be within walking distance to social
infrastructure, reducing demands for transportation. Public transportation will use emission-
free technologies, and visitors will leave vehicles that expel tail pipe emissions outside the
city. Green roofs and advanced building technologies, including natural ventilation, will
reduce building energy demands. Electricity will be produced from renewable sources,
including photovoltaic cells, wind turbines, and biogas from municipal waste and sewage. In
addition, a combined heat and power plant running on biomass waste from agriculture will
provide district heating. Energy will also be managed through resident education, smart
metering, and financial incentives. The development is planned to have near-zero carbon
emissions.

International 2007). The 2031 scenarios are future projections of GHG emissions for the
City. These scenarios consider reductions due to currently planned municipal and provincial
policies (Planned-Policies) and alternative actions that could be considered aggressive
(Aggressive-Alternatives). The GHG emissions and potential savings in all scenarios focus
on the sectors responsible for the largest amounts of emissions: Buildings (including
building relevant Energy Supply) and Transport.
Base-Case Scenario for 2004
In 2004, the population of the City of Toronto was about 2.65 million, and the city’s gross
domestic product was about 101.7 billion dollars (based on provincial GDP weighted by
employment data). The total land area for the City, kept constant in all scenarios, is about
63,000 hectares.
Buildings
The gross-floor-area (GFA) of Toronto’s building stock in 2004 was estimated using roof
areas and building heights provided by the City for the following building categories: Low-
Rise Residential; Apartments; and Commercial-Institutional. The GFA was estimated based
on assumptions of floor height. For Low-Rise Residential buildings and Apartments, the
estimated GFA was taken to be the average of the two total GFA values calculated assuming
both 10ft and 12ft ceilings. For Commercial buildings, 12 ft and 14 ft ceilings were assumed.
The total GFA of the Toronto building stock in square kilometres for each building type is
shown in Table 8.
The total energy consumption (in GJ) of each building type was calculated as the product of
building stock (in m2) and energy intensity (in GJ/m2), using the energy intensity values for
Ontario, shown in Table 9. The total energy consumption was further divided according to
end use: a portion of the total energy represents heat, and a portion represents electricity.
In Toronto, heat is generally fuelled by natural gas. Heating energy end uses are space
heating and water heating, and electrical energy end uses are lighting, appliances, and
space cooling. Toronto’s split between natural gas and electricity, as well as the Canadian
average split in end use consumption of natural gas and electricity, is also shown in Table 9.
The total energy consumption of the 2004 Toronto building stock, as well as the energy
associated with each end use, is shown in Table 8. GHG emissions (tCO2e) from heating

fuels were calculated as follows:
fuelfuelfuel ICGHG ⋅= (5)
where Cfuel (TJ) is the amount of fuel consumed, and Ifuel (tCO2e/TJ) is the GHG emissions
intensity. For natural gas, the principle heating fuel in Toronto, the GHG emissions intensity
38
is 56.1 tCO2e/TJ (IPCC 2006). GHG emissions (tCO2e) attributable to total electricity
consumption were determined by:
yelectricityelectricityelectricit ICGHG ⋅= (6)
where Celectricty (GWh) is the total electricity consumption. The GHG emissions intensity,
Ielectricity (tCO2e/TJ), for the Province of Ontario including line losses is 246 gCO2e/kWh (68.3
tCO2e/TJ). Overall, the building sector was responsible for about 14 megatonnes of GHG
emissions in Toronto in 2004.
Transport
GHG emissions associated with transport were calculated using the MUNTAG model (Derrible
et al. 2010) with inputs such as Toronto’s 2004 population, land area, GDP, and information
about the transit and bicycle infrastructure. The 2007 transit infrastructure for Toronto was
available from the Toronto Transit Commission (Toronto Transit Commission 2008), and
given there were no major infrastructure changes, it was assumed to be similar to the 2004
infrastructure:
• 1545 Buses
• 248 Streetcars, 69.2 km of Streetcar tracks
• 706 Subway cars, 68.3 km of Subway tracks
The resultant vehicle-kilometres traveled, VKT (km), of each motorized mode – private
automobiles, bus, streetcar, and subway – is shown in Table 10. The total length of
Toronto’s bicycle facilities was 403 km (City of Toronto 2009a), resulting in an estimated
bicycle mode share of 0.88%. This mode share fraction was subsequently subtracted from
the GHG emissions of each motorized mode.
GHG emissions (gCO2e) from transport were determined by:
fueleee INVKTGHG ⋅⋅= modmodmod (7)
The total vehicle-kilometres traveled, VKTtransport mode (km), for each mode was provided by
the MUNTAG model. The emissions factor for each mode (gCO2e/km), shown in Table 10, is
the product of the mode’s energy intensity, Ntransport mode (MJ/km), and the fuel GHG
emissions intensity, Ifuel (gCO2e/MJ). The energy intensity for each mode was taken as the

North American average from the Millennium Cities Database (UITP 2001). IPCC defaults
were used for the GHG emissions intensity of diesel and gasoline (75.2 tCO2e/TJ and 72.2
tCO2e/TJ respectively; IPCC 2006). For electric modes, including streetcars, LRTs, and
subways, the GHG emissions intensity was taken to be that of the provincial electricity
supply (68.3 tCO2e/TJ).
The final results of the MUNTAG model, including the GHG savings due to the bicycle mode
share, are shown in Table 10. The results indicate that in 2004 passenger transport
contributed about 3.2 megatonnes to Toronto’s GHG footprint.
Comparison to City of Toronto Inventory
Emissions calculated using the Getting to Carbon Neutral guide were comparable to values
presented in the 2004 Toronto GHG Inventory (ICF International 2007), as shown in Table
11. For the sources of emissions that were common to both methods – including low-rise
residential homes, apartments, and commercial buildings, as well as private automobiles
and transit buses – there was only a 2% to 17% difference in numerical values. The current
version of Getting to Carbon Neutral excludes emissions from industrial buildings, trucks,
and waste; however, the calculations for other sources were shown to be verifiable.

Planned-Policy Scenario for 2031
The Province of Ontario and the City of Toronto are implementing numerous plans and
initiatives to reduce GHG emissions. Using the Estimation Guidelines provided in the Getting
to Carbon Neutral guide, the GHG impacts of a few of the policies are quantified in this
scenario for the year 2031.
Following the linear population growth trend described in Ontario’s Growth Plan for the
Greater Golden Horseshoe (Ministry of Public Infrastructure and Renewal 2006), the
population of Toronto in the year 2031 will be about 3.08 million. The city’s GDP is projected
to be 178 billion dollars, and the land area will remain the same at 63,000 hectares.
Buildings
To extrapolate the building stock into the year 2031, the Growth Plan’s population trends,
employment trends, and residential housing construction trends were followed. The total
residential GFA (the sum of Low-Rise Residential and Apartments) was assumed to grow at
the same rate as population, which will increase 16% by 2031. Ten percent of the increase
in residential GFA was assigned to Low-Rise Residential housing and the remaining 90% was
41
assigned to Apartments. Commercial GFA was assumed to grow at the same rate as
employment, which is projected to increase 10% by 2031. The extrapolated building stock
values are shown in Table 12.
Following the same method used in the 2004 Base-Case Scenario, the total energy used by
each building type was calculated according to the intensity and energy breakdown schemes
in Table 9. The total emissions were also calculated according to Equations (5) and (6). The
emissions intensity of natural gas remained at 56.1 tCO2e/TJ, and the projected Integrated
Systems Plan electrical emissions intensity (including line losses) was taken to be 37.8
gCO2e/kWh (10.5 tCO2e/TJ) (Ontario Power Authority 2006). The total energy and
emissions before savings is shown in Table 12.
In addition to using the electricity emissions intensity of the Province’s Integrated Systems
Plan, which will promote small-scale urban renewable generation, five initiatives were
quantified in this scenario: banning incandescent bulbs; requiring ENERGY STAR appliances;
implementing the 2012 Ontario Building Code; completing the Mayor’s Tower Renewal
project; and promoting commercial green roofs.
Banning incandescent bulbs
The ‘Energy Efficient Appliances’ Estimation Guideline indicates a 75% energy savings for
CFL bulbs over incandescent bulbs. Assuming 70% of residential lighting energy and 10% of
commercial lighting energy is currently from incandescent bulbs, the energy savings to
lighting electricity is 52.5% and 7.5% respectively. This will result in a total GHG savings of
about 40.1 kilotonnes (Table 12).
Requiring ENERGY STAR Appliances
The ‘Energy Efficient Appliances’ Estimation Guideline offers a range of potential savings
based on different ENERGY STAR appliances. The average savings were taken as 30% for
these calculations, and it was assumed 60% of residential appliances and 30% of
commercial appliances were not already ENERGY STAR rated. The energy savings to
appliance electricity was therefore 18% for residential buildings and 9% for commercial
buildings, which will result in a total GHG savings of about 61.5 kilotonnes.
Implementing the 2012 Ontario Building Code
The planned 2012 Ontario Building Code will require that all new homes are built to a higher

Buildings’ Estimation Guideline states that R2000 homes use 30% less energy than
conventional homes. Implementing this standard for low-rise residential buildings would
reduce the increase in space heating energy between 2012 and 2031 by 30%. This energy
savings will correspond to a reduction of 14.8 kilotonnes of GHG emissions.
Completing the Mayor’s Tower Renewal Project
The Mayor’s Tower Renewal Project will aggressively retrofit existing 1960’s-era high-rise
towers, as well as promote neighbourhood revitalization initiatives (Kesik et al. 2008). To
simulate the effects of this, a 30% savings on space heating energy was applied to all
Toronto Community Housing Corporation buildings, as per the ‘Building Retrofits’ Estimation
Guideline. It is important to note that this was a conservative estimate; Kesik et al. (2008)
have simulated much larger savings for some buildings. ICF International (2007) showed
that Community Housing Corporation buildings currently require about 2.9 million GJ of
space heating energy a year. Reducing space heating needs by 30% will save 49.4
kilotonnes of GHG emissions.
Promoting commercial green roofs
The ‘Vegetation’ Estimation Guideline describes green roofs as reducing peak summer
cooling loads by 25% in roofs immediately below the green roof. The green roof initiative
43
targets to cover 10% of commercial buildings with green roofs (City of Toronto 2009b).
Assuming the savings would apply to 10% of the cooling energy used by commercial
buildings, the total percentage savings to space cooling electricity would be 0.25%. This
would result in a GHG savings of 0.3 kilotonnes.
Based on the values presented in Table 12, the initiatives that will have the greatest impact
to GHG emissions are the Mayor’s Tower Renewal Project, requiring ENERGY STAR
appliances, and banning incandescent bulbs. All five initiatives have a combined GHG
savings of about 166 kilotonnes. These initiatives, combined with the lower electrical
emissions intensity resulting from Ontario’s Integrated Systems Plan, will cause Toronto’s
buildings to be responsible for 10.6 megatonnes of GHG emissions in 2031.
Transport
The most significant transport-related government initiative currently planned for Toronto is
the Greater Toronto Area’s Metrolinx Plan (Metrolinx 2008), which will increase availability
of public transport. The three other initiatives that were quantified in this scenario include:
an increased adoption of electric vehicles; an increase to the length of bicycle facility; and a
10% increase in parking price to deter auto use.
Subway and LRT
The Metrolinx Plan will result in numerous upgrades to the current TTC infrastructure. The
Plan will increase subway routes and construct new LRT lines. Assuming the same number
of buses as in 2008, as well as a maintained ratio of transit carriages to track length, the
new Metrolinx infrastructure in 2031 will consist of:
• 1737 Buses
• 248 Streetcars, 65.6 km of Streetcar tracks
• 1063 Subway cars, 102.85 km of Subway tracks
• 452 LRT cars, 126 km of LRT tracks
The calculated VKT of each motorized mode in 2031 is shown in Table 13.
The emissions factor (gCO2e/km) in 2031 of electrically operated motorized modes (shown in
Table 13) will be different from the 2004 Base-Case due to the Province’s Integrated
Systems Plan for electricity supply. The emissions factors for diesel buses remain the same;

however, the emissions factor of streetcars, LRTs, and subways changes with a lower GHG
intensity of electricity (10.5 tCO2e/TJ).
Increasing adoption of personal electric vehicles
Current provincial government initiatives aim to increase the market share of electric
vehicles to 5% by 2020 (Office of the Premier 2009). Assuming an exponential increase in
years following, the percentage of private automobile vehicle-kilometres traveled by electric
vehicles was projected to be 20% in 2031. Electric engines operate more efficiently than
internal combustion engines, and their energy will be supplied by electricity generated
according to the Province’s Integrated Systems Plan. Therefore, the emissions factor for
electric vehicles is quite lower than other modes, estimated at 93.55 gCO2e/km.
45
Increasing length of bicycle facility to promote active transport
The bicycle facility in Toronto is planned to increase from 403 km to 1004 km by 2012 (City
of Toronto 2009a). Assuming this length of facility stays constant through to 2031, it will
result in an active-transport mode share of 1.31%. This mode share, applied across all
modes, will result in a total GHG savings of about 25.1 kilotonnes.
Increasing parking price to deter auto use
While official plans to increase parking prices are not known, a conservative estimate of
10% was made. According to the ‘Parking Price Increase’ Estimation Guideline, this will
result in a mode share decrease of 0.70% for private automobiles and a mode share
increase of 0.10% for public transit. The combined effects of these mode share changes will
result in a savings of about 11.7 kilotonnes of GHG emissions.
The final results of the MUNTAG model for the Metrolinx infrastructure, including the GHG
emissions savings from each government initiative, are shown in Table 13. The most
significant savings are associated with changing 20% of personal vehicles to electric
vehicles. When combined, the planned initiatives will reduce transport related GHG
emissions to about 3.1 megatonnes in 2031.
Alternative-Aggressive Scenario for 2031
The Alternative-Aggressive Scenario explores the GHG emissions in 2031 associated with
making aggressive changes to Toronto’s buildings and transport infrastructure. The changes
were drawn from some of the most innovative case studies in Getting to Carbon Neutral
guide, and their impacts were quantified using the corresponding Estimation Guidelines.
This scenario represents one aggressive plan that could help Toronto get closer to carbon
neutral.
Buildings
The 2031 building stock and associated emissions before savings are the same as in the
Planned-Policy Scenario; however, the savings in this scenario are more aggressive. In
addition to expansion of the initiatives described above, changes involving buildings retrofits
and innovative energy systems were applied. Overall, several energy-saving measures were
used to reduce emissions: replacing all light bulbs with LEDs and all appliances with ENERGY
STAR rated appliances; retrofitting all buildings built before 2012; designing all buildings
after 2012 to low-energy standards; implementing Borehole Thermal Energy Storage
46
(BTES) systems, solar water heating, and ground-source heat pumps in low-rise residential
homes; outfitting half of all apartment buildings with Aquifer Thermal Energy Storage
(ATES) systems; and outfitting commercial buildings with solar air heating and 25% green
roof coverage.
LED light bulbs and ENERGY STAR appliances
LED bulbs use less electricity than both incandescent and CFL bulbs. They are approximately
90% more efficient than incandescent bulbs and 60% more efficient than CFL bulbs.
Assuming the same percentages of incandescent lighting as in the Planned-Policy Scenario
(70% of residential lighting energy and 10% of commercial lighting energy), and assuming
the remaining lighting energy is currently met with CFL bulbs, implementing CFL bulbs
would save 81% of lighting electricity in residential buildings and 63% of lighting electricity
in commercial buildings. This would correspond to savings of about 150 kilotonnes of GHG
emissions. Following the previous method for ENERGY STAR appliances, they would again
save about 61.5 kilotonnes of GHG emissions.
Retrofitting pre-2012 buildings
The ‘Building Retrofits’ Estimation Guideline states that retrofitting can reduce energy
demand by 30% for apartments and commercial buildings and can save up to 50% for low-
rise residential homes. Taking the average energy savings to be 30% for all building types,
the potential GHG emissions savings associated with retrofitting all buildings constructed
before 2012 was calculated to be about 2.7 megatonnes.
Designing post-2012 apartments and commercial buildings to low-energy standards
The emergence of accreditation for sustainable buildings has increased the popularity of
low-energy apartments and commercial buildings. According to the ‘New Energy Efficient
Buildings’ Estimation Guideline, these buildings can be designed to consume 60% less
energy than standard. When applied to all apartments and commercial buildings constructed
after 2012, there would be a savings of about 425 kilotonnes.
Designing post-2012 low-rise residential homes to low-energy standards with BTES systems
As demonstrated by the Drake Landing Solar Community in Alberta (Box 5), R2000 homes
combined with a Borehole Thermal Energy Storage system use 90% less space heating
energy than a typical community. If all new low-rise homes in Toronto built after 2012 were
designed with the same specifications – R2000 energy standards combined with a BTES
system – they would save 61.3 kilotonnes of GHG emissions in 2031.
47
Box 5: Drake Landing Solar Community, Okotoks, Alberta
The Drake Landing Solar Community is comprised of 52 single family R-2000 homes. The
homes are connected to a district heating system that includes solar collectors and a
borehole energy storage system. The borehole field consists of 144 boreholes, each 35 m
deep, 150 mm diameter, 2.25 m spacing. The system contains 24 parallel circuits, each
having 6 boreholes in series. During the winter the homes are heated using solar energy
captured during the summer and stored in the boreholes. This system saves more than 110
GJ of energy and 5 tCO2e per home each year. Overall, 90% of the space heating needs are
met by solar thermal energy.
Source: Adapted from Kennedy (2010).
Solar water heating and ground-source heat pumps in pre-2012 low-rise homes
Outfitting low-rise residential homes built before 2012 with solar water heating and ground-
source heat pumps would also decrease fossil-fuel based energy consumption. The ‘Solar
Water Heating’ Estimation Guideline assigns 45% savings to water heating energy needs
with the addition of solar heaters in Toronto. If these savings were applied to all pre-2012
low-rise residential homes in the city, 445 kilotonnes of GHG emissions would be avoided.
Taking an average of the savings described in the ‘Ground Source Heat Pumps’ Estimation
Guideline, outfitting all pre-2012 low-rise residential homes with ground source heat pumps
would save 30% on both space heating and space cooling needs – equivalent to a GHG
emissions savings of 791 kilotonnes.
ATES systems in half of all apartment buildings
The geology in many areas of Toronto is well-suited for Aquifer Thermal Energy Storage
systems, which can provide 25% savings to heating energy and 70% savings to cooling
energy needs. If half of all apartment buildings in Toronto were serviced with an ATES
system, this would result in a total GHG emissions savings of about 223 kilotonnes.
Solar air heating and green roofs on commercial buildings
The Canadair Facility Solarwall (Box 6) is an example of an effective solar air heating
strategy reducing emissions associated with space heating of commercial buildings.
According to the ‘Solar Air Heating’ Estimation Guideline, there is the potential for 25-47%
saving to space heating energy. Using the conservative estimate that 30% energy savings is
48
Box 6: Canadair Facility Solarwall, Dorval, Quebec
Bombardier's Canadair facility in Dorval is home to the world's largest solarwall. The wall is
covered with millions of tiny holes about 1 mm in diameter which allow outside air to pass
through. It is approximately 30 cm away from the main structure of the building which
creates a cavity for air flow. As outside air is drawn into the cavity, it flows upwards and
picks up the solar heat that the wall absorbs. When the heated air reaches the top of the
structure, it is either mixed with recirculated air and used to condition the space, or sent to
the gas fired make up unit if more heat is required. Monitoring results show the combined
effects from the solarwall, reduced heat loss, and destratification of indoor air results in a
savings 720,400 m3 of natural gas per year, reducing annual GHG emissions by 1,342
tCO2e.
Source: Adapted from Kennedy (2010).
possible for commercial buildings in Toronto, solar air heating applied to all commercial
buildings would save about 966 kilotonnes of GHG emissions. The green roof initiative
described previously could be aggressively extended to target to cover 25% of commercial
buildings with green roofs. Assuming the ‘Vegetation’ Estimation Guideline’s 25% savings to
peak cooling needs would again apply to 10% of the cooling energy consumed, this would
result in a savings of 0.7 kilotonnes of GHG emissions.
When combined, all the aggressive savings strategies would result in a reduction of about
5.8 megatonnes of GHG emissions from buildings, as shown in Table 14. The strategies with
the most significant reductions are building retrofits, commercial solar air heating, and low-
rise residential ground source heat pumps. With the aggressive savings, buildings would
account for about 4.9 megatonnes of emissions in 2031 Toronto.
Transport
The transport-related emissions quantified in this scenario involve aggressive changes to
transit infrastructure, vehicle technology, and bicycle infrastructure. In addition, aggressive
auto-use deterrents, such as increased parking fees, taxes, and tolls, would provide further
emissions savings.

Improved transit infrastructure
The current Metrolinx plan will promote significant improvements to public transit by 2031.
To examine an aggressive alternative to the current plan, GHG savings were quantified
assuming all planned LRT lines would instead be constructed as subway lines. This would
cause a significant shift away from automobile use to public transit, resulting in a total
emissions savings of about 686 kilotonnes.
50
Complete shift to electric vehicles
Aggressive actions to completely shift vehicle technology from internal combustion engines
using gasoline to electrically powered engines would cause a dramatic reduction in the
overall GHG emissions intensity of automobiles. An advanced electric vehicle infrastructure
network, such as Better Place’s Electric Vehicle Network in Israel (Box 7), would promote
this shift. Replacing all automobiles with electric vehicles in 2031 would save 1.7
megatonnes of GHG emissions.
Improved bicycle infrastructure
The current plan for the bicycle infrastructure in Toronto is to increase the length of the
bicycle facility to 1004 km by 2012. Continuing to increase linearly through to 2031 would
result in a bicycle facility 2431 km in length. With this aggressive increase, the active
transport mode share would be 2.33% applied across all modes, resulting in potentially 26.7
kilotonnes of emissions saved.
Increased parking price
As in the Planned-Policies Scenario, the conservative parking price increase of 10% would
result in a mode share decrease of 0.70% for private automobiles and a mode share
increase of 0.10% for public transit. When applied to the alternative transit infrastructure
proposed in this scenario, this would result in GHG savings of about 6.2 kilotonnes.
Introducing taxes and tolls
When ‘Tolls, Taxes, and Area Pricing’ strategies are applied to Toronto in 2031, the mode
share changes resulting from a VMT tax and a Freeway toll would save 133.6 and 19.2
kilotonnes of GHG emissions respectively. Toronto could also effectively implement a
Beltway Cordon along the city limits and charge vehicles entering the city to further deter
auto use; however, this is not quantified in this scenario, as it would mostly impact
commuters from surrounding areas.
The aggressive methods in this scenario would result in a total of 2.6 megatonnes of
emissions saved (Table 15), with the most significant measures including shifting from
internal combustion to electric vehicles and switching LRT to subway lines. With all
aggressive savings employed, transport would contribute 0.96 megatonnes to Toronto’s
2031 GHG footprint.

Summary and Conclusions
The three scenarios presented in this paper represent potential greenhouse gas emissions
situations for the City of Toronto under different levels of climate action. The Base-Case
Scenario acts as a baseline, illustrating the current level of emissions from which emissions
Box 7: Better Place Electric Vehicle Network, all cities in Israel
In addition to future projects in Australia and Denmark, sustainable transportation company
Better Place is developing an electric vehicle network in Israel. The electric car
infrastructure will consist of electric vehicles and innovative battery technology, as well as
battery exchange stations and charging spots powered by renewable energy. Charging spots
will be located around a community, so that batteries are automatically charged as vehicles
are parked. For longer trips (greater than 100 miles), roadside battery switching stations
will replace depleted a battery with a fully charged one. The experience will be automated,
never requiring the driver to leave the vehicle. The business model is similar to that of a
mobile phone carrier whereby users pay for use of the network and the vehicles cost is low.
If electricity is obtained from renewable sources, the electric vehicle network will result in
zero transportation emissions.

will grow significantly if a business-as-usual approach is taken. However, the municipal and
provincial governments have recognized the importance of action on climate change, and
they have proposed a variety of policies intended to reduce GHG emissions. The GHG
emissions resulting from these policies are projected to 2031 in the Planned-Policies
Scenario.
Assuming the currently planned policies and initiatives will be implemented by 2031,
buildings and passenger transportation will account for 13.7 megatonnes of GHG emissions,
53
or 4.44 tonnes per capita (Table 16). Compared to the 2004 Base-Case Scenario, this
represents a 31% savings in GHG emissions per capita. A large portion of this is due to the
reduced electrical emissions intensity associated with the Province’s Integrated Systems
Plan, as well as reduction in internal combustion automobile use. The other initiatives
outlined in this scenario provide relatively modest GHG savings, which opens potential
opportunities for significant savings to be achieved through more aggressive actions.
The third scenario presented in this paper, the Aggressive-Actions Scenario, offers a bold
infrastructure plan for Toronto that would reduce GHG emissions significantly. The plan goes
far beyond the current climate action proposed by the provincial and municipal
governments, but it is not out of line with global best practices in sustainable infrastructure.
With these aggressive actions taken, Toronto’s buildings and transport related GHG
emissions in 2031 could be reduced to 5.9 megatonnes, or 1.91 tonnes per capita (Table
16). In addition to the Province’s Integrated Systems Plan, the most significant contributors
to savings involve retrofitting all existing buildings, utilizing renewable heating and cooling
systems, and the complete proliferation of electric automobiles. Compared to the 2004
Base-Case Scenario, the aggressive actions suggested in this scenario could reduce GHG
emissions per capita by 71%.
The bold infrastructure plan for Toronto presented in this paper demonstrates that equally
as aggressive plans could be successfully conducted for any municipality in Canada.
Individually, projects invoking these strategies are demonstrating success in cities
throughout the world. When treated as systems working together, these strategies have
allowed for the creation near carbon neutral communities, such as Dockside Green and
BedZED, and even planned carbon neutral cities, such as Dongtan. Implementing bold,
innovative actions that challenge and renew existing infrastructure is a critical component of
an effective climate action plan, and the only way for our cities to get to carbon neutral.

Chapter 4 Synergies Between Adaptation and Mitigation in
Development: Case Studies from Amman, Jakarta, and
Dar es Salaam
Introduction
The majority of the world’s population now lives in cities and, for many of those urban
residents, poverty is widespread. Inadequate access to water, energy, food, and
employment are all realities of daily life. A changing climate will exacerbate the issues faced
by the urban poor: climate change is a problem primarily caused by the rich will affect poor
most severely (Bartlett et al. 2009; Hoornweg et al. 2010). Urban development must
improve the quality of life for the urban poor, now and as the climate changes, without
contributing greenhouse gas (GHG) emissions.
The potential to combine strategies for mitigation and adaptation is of great interest in the
literature – especially in the urban context. Experts contend that mitigation and adaptation
need not compete for development resources, for they are complementary pursuits
(Wilbanks and Sathaye 2007). Wilbanks et al. (2003) describe how mitigation and
adaptation target different geographical and temporal scales: mitigation is global with long-
term impacts, and adaptation is local with short-term impacts. Therefore, if mitigation can
keep climate change moderate, adaptation can take case of the rest. Such a synergetic
approach is essential to incorporate into urban planning practices (Susskind 2010). Venema
and Rehman (2007) and Simon (2010) bring up challenges unique to Africa: energy is a
sector to target. Energy poverty, if left unaddressed, contributes to climate change with
deforestation and biomass burning, while making poor populations even more vulnerable to
climate impacts. It becomes clear that in developing regions, strategies that can address
both mitigation and adaptation simultaneously will be the most efficient use of limited
resources.
This paper presents case studies of three cities: Amman, Jakarta, and Dar es Salaam. The
objective of the case studies is to address the dual problem of mitigation and adaptation,
providing insight into the climate vulnerabilities, greenhouse gas impacts, and low-carbon,
adaptive development opportunities of urbanizing regions in developing countries. The
58
challenges of sustainable development today are immense; each city is at a different stage
in the development process and faces unique everyday circumstances.
Amman is the largest city in Jordan: home to 2.8 million people. The population growth in
the city accelerated in the later half of the last century, as Amman has been a place of
refuge for those escaping from neighbouring conflict zones. The majority of the population
in Jordan is under the age of 25 (WDI 2008). The climate is moderate with seasonal
variations and cool winter months. The annual per-capita income in Jordan is about
US$3,600 on average (WDI 2008), and the economy in Amman is primarily service-based.
Jakarta is on the northwest coast of Java, Indonesia; with a population of nine million, it is
the archipelago’s largest city. The climate is tropical, with warm temperatures and an eight-
month long rainy season. Economic activity centres on services, finance, and
manufacturing. The average income per capita in Indonesia is about US$2,250, growing at a
rate of 6.1% per year (WDI 2008).
Dar es Salaam is the largest city in Tanzania, and although not the capital of the country, it
is considered a hub for business, government, and transportation. The population is
approaching three million, growing recently at a rate of 6% per year (Kimbisa 2010). The
climate is tropical, and the average income per capita of Tanzania is about US$500 per year
(WDI 2008). The local job market centres on manufacturing and natural resources, such as
fishing, and many people support themselves with entrepreneurial enterprises.
The amount and severity of urban poverty in each city varies. In all three cities, the poor
live primarily in unplanned areas that are not connected to basic municipal services. In
Amman, while the economy is flourishing, there are still portions of the population that live
in unsafe squatter settlements without access to reliable services. The poor in Amman are
primarily refugees from conflicts in neighbouring regions (Tavernise 2007), and the
government has made housing upgrade projects and infrastructure access for poor
communities a development priority (Gerlach and Franceys 2009; Bisharat and Tewfik
1985). Unplanned settlements in Jakarta are known as kampungs. The kampungs are not
equipped with reliable water or energy infrastructure, some are located in flood-prone
areas, and they are not exclusive to the urban poor: some kampung residents have low- to
mid-range incomes (Argo and Laquian 2007; Rustamadji 1992).
In Dar es Salaam, the contrast between the rich and the poor is most extreme. The rich live
in comfortable, planned developments with access to water, electricity, and cars. The poor
59
majority (nearly 70%) inhabits over populated, unplanned slum settlements without basic
municipal infrastructure, including roads, water, and sewerage (Government of Tanzania
2000; Tweehuysen and Hayes 2006). The conditions in the slums are worsened by everyday
behaviour caused by desperation. Biomass is burned in the home for cooking, which
produces soot that deteriorates interior air quality (Sanderson 2000). Solid waste, human
waste, and wastewater are dumped in the streets to decompose, where they contaminate
the meagre water supply and spread dysentery and disease (Victor et al. 2008). While the
problems in Dar es Salaam are seemingly overwhelming, city officials have successfully
taken steps to upgrade some areas.
The three case studies demonstrate different interactions with the issue of climate change.
This paper will first outline the chief issues associated with climate change for each city.
Next, greenhouse gas inventories for each city are presented, as well as associated data
and methodological issues. Finally, the cities’ current plans to address climate change are
presented, along with some further suggestions of synergetic opportunities for mitigation,
adaptation, and development.
The Vulnerabilities of Cities to Climate Change
The Intergovernmental Panel on Climate Change (IPCC) has given some dire predictions of
the consequences of climate change (IPCC 2007). Some consequences include: a decrease
of water availability in dry areas by up to 30%; sea-level rise; and increased ocean
temperatures that disrupt ecosystems and intensify storms. For cities, these consequences
take on a life of their own. The infrastructure in cities, or lack thereof, has profound impacts
on how severely the consequences of climate change are experienced. In cities with strong
emergency systems, diverse power sources, and well-coordinated drainage and water
systems, climate change may be more easily managed. However, the majority of cities in
developing regions of the world do not even have the infrastructure to provide for all of their
citizens on a daily basis, let alone adjust to disruptions caused by climate change. It is in
these cities that the impacts of climate change will be most severe.
In Amman, the most climate-sensitive municipal service is water. Jordan is exceptionally
dry, and nearly 15% of all electricity consumption is by the Water Authority of Jordan (GTZ
2004). Accordingly, Amman uses approximately 825 GWh of electricity to pump water each
year (see the urban metabolism diagram for Amman, Figure 7). With climate change, water
scarcity will become more severe. While Amman has nearly a one-hundred percent

connection rate to the municipal water supply, providing a consistent water flow is
something authorities are already struggling with (Gerlach and Franceys 2009).
The projected sea-level rise and flooding are risks in Jakarta. The city has already
experienced extreme flooding, with flooding being most severe in low-elevation kampungs
(Texier 2008). Floods, landslides, and sea-level rise are all risks for Jakarta (Bowo 2010).
The climate vulnerabilities associated with sea-level rise are intensified by local actions:
parts of Jakarta are already subsiding because of an over-exploitation of ground water and
soil compression from heavy construction (van Sluis and van Aalst 2006).
In Dar es Salaam, alternating floods and droughts are climate impacts already experienced.
The city is witnessing an unprecedented influx of climate refugees from rural areas (Kimbisa
2010), which puts increased pressure on already strained services. Flooding in Dar es
Salaam is intensified by the poor drainage infrastructure (Mwandosya et al. 1998), causing
roads to be washed out and economic activity to be put on hold. The droughts are also
impacting Tanzania’s electricity infrastructure: a low water level disrupts hydroelectricity
production, requiring new natural gas infrastructure to maintain power. Not only is this
response expensive, it also increases greenhouse gas emissions that further the climate
problem.
The climate vulnerabilities of the three cities point to a common theme: infrastructure that
is resilient to extreme circumstances will be the best response to climate change. As
demonstrated by the example of electricity in Tanzania, development responses should not
exacerbate the climate change problem by producing greenhouse gas emissions. Similarly,
the water situation in Amman shows that infrastructure access and supply need to be
considered in concert. A big picture perspective is needed that address impacts as well as
contributions to climate change.
Determining Greenhouse Gas Emissions from Cities
Greenhouse gas emissions from developing cities, though sometimes challenging to
quantify, can give insight into urban activities that are contributing to the climate change
problem. Cities in developing economies to not generally emit as many emissions per capita
as cities in developed regions, simply because the quality of life and consumption practices
are lower on average. However, conducting an inventory of emissions by sector is the first
step towards targeting the most effective low-carbon development strategies for a given
city.
62
Methodology and Data Sources
The greenhouse gas inventories for Amman, Jakarta, and Dar es Salaam were conducted
following the methodology of Kennedy et al. (2010) and the Standard for Determining
Greenhouse Gas Emissions from Cities (UNEP et al. 2010), which is a city-scaled version of
the Intergovernmental Panel on Climate Change (IPCC) methodology for nations (IPCC
2006). The urban GHG inventory is a hybrid of a consumption and production inventory;
that is, it includes GHG emissions produced within the city boundary, as well as emissions
that are a direct result of urban activity. For example, the inventory includes emissions from
heating, industrial, and transportation fuels, as well as electricity consumption (though
electricity production often takes place outside the urban boundary).
The IPCC defines four categories of emissions: Energy (stationary and mobile combustion of
fossil fuels); Industrial Processes and Product Use (non-energy related emissions);
Agriculture, Forestry, and Other Land Uses (AFOLU); and Waste. In cities, the most
significant categories of emissions are Energy (fossil fuel combustion and electricity
consumption) and Waste. Some cities have high Industrial Process emissions (e.g. Chinese
cities, see Chapter 2), but these emissions are not considered for the three cities studied in
this paper. Amman and Dar es Salaam do not have significant industrial activity, and the
industrial data for Jakarta is currently unavailable. Similarly, AFOLU emissions are not
included for lack of available data; however, they are estimated to be insignificant for the
three cities based on previous studies conducted in other cities (Kennedy et al. 2009).
In general, GHG emissions are calculated as follows:
FactorEmissionDataActivityEmissionsGHG ×= (8)
Activity data varies with inventory component; for example, the amount of energy
consumed and the amount of waste produced are both forms of activity data for their
respective sectors. Both the activity data and GHG intensity are required to complete
calculations. For the three cities studied, GHG intensities are either based on national
averages or IPCC default values.
The greenhouse gas inventories for Amman, Jakarta, and Dar es Salaam were conducted in
collaboration with city officials and local consultants to give an ‘on-the-ground’ advantage to
data collection. Officials were able to access statistical data and engage local experts to
provide reasonable estimations. For Amman, city officials from the Greater Amman
Municipality were able to provide data for all necessary sectors; when needed, national data
63
was scaled to values appropriate to the local context and confirmed with city officials. Data
for Jakarta was readily available, as local consultants had recently conducted a thorough air
quality report outlining sources of carbon dioxide, methane, and nitrous oxide (Suhadi
2009). The inventory data for Dar es Salaam was the most difficult of the three cities to
acquire, for it is where the conditions of poverty are most extreme. Local officials,
academics, and development agencies were able to provide some data, and the remaining
data was scaled from national statistics to the urban context. It is important to note that the
three urban GHG inventories presented in this paper are an important first step; future
inventories will improve as urban data collection becomes more thorough and the practice of
inventorying becomes a higher priority to cities.
Results
The urban characteristics of the cities are well represented in their GHG inventories. In the
study year, Amman, Jakarta, and Dar es Salaam produced 10.3 megatonnes, 44.6
megatonnes, and 1.6 megatonnes of carbon dioxide equivalent emissions respectively
(Figure 8; Table 17; full standard tables for Amman, Jakarta, and Dar es Salaam are shown
in Appendices D-F). The major contributors of emissions are highly dependent on the
amount and type of urban infrastructure in each city.
Emissions from road transportation were quite high in all three cities, accounting for 28%,
27%, and 49% of the total emissions from Amman, Jakarta, and Dar es Salaam
respectively. In all cities, there is little in terms of a public transportation infrastructure: the
public transportation networks are still growing, and privately owned automobiles are still
the mode of choice for those who can afford them. In all the cities, mass transit takes the
form of buses or mini-buses, which give mobility access to more people but do not
necessarily take private cars off the road.
Electricity consumed in the cities had varying impacts on the greenhouse gas inventories,
primarily due to differing levels and methods of generation (Table 18). Emissions from
electricity for Amman and Jakarta were quite high: 37% and 59% respectively. This can be
attributed to high levels of electricity generated using fossil fuels. Dar es Salaam, however,
had the lowest percentage of emissions from electricity (7%), chiefly because electricity is
generated primarily from hydropower and service is inconsistent.
Waste in all three cities is managed at landfill sites, with a small portion composted in
Jakarta. The percentages of emissions from waste are quite low in Amman and Jakarta:

10% and 7% respectively. However, waste in Dar es Salaam produced 32% of total
emissions. It is important to note that waste emissions only account for waste that is
collected and managed by the cities; in reality, waste in unplanned settlements is collected
rarely and may not be collected at all.
Given that these inventories are the first for all three cities, there are some emissions that
are left unaccounted for. Emissions from fossil fuel combustion in the industrial, commercial,
and residential sectors were available for Amman and Jakarta (15% and 7% respectively),
but not for Dar es Salaam as the data was not available. Similarly, emissions from the
aviation and marine sectors were not calculated for Jakarta because the ports lie outside the
66
city boundary, and assigning emissions based on city-related port use was not possible due
to lack of available data. However, given their statuses as regional business and commercial
hubs, aviation in Amman and Dar es Salaam were significant, accounting for 10% and 12%
of total emissions respectively.
In examining the greenhouse gas inventories of the three cities, it is important to revisit the
living conditions of the urban poor. Those living in poverty do not have access to the same
energy, water, or waste management infrastructure as other urban residents. Therefore, it
becomes important to question to what degree the inventories reflect the consumption
habits of the entire city. One may argue that the inventories focus primarily on residents
living in well-connected areas of the city, though this is a topic requiring further research.
An understanding of the attribution of emissions within the city will help inform sectors best
suited for either mitigation measures or low-carbon development.
Development Opportunities
As demonstrated in previous sections, the level of service access, climate change
vulnerabilities, and greenhouse gas emissions in the study cities are all different, which
demands unique and innovative solutions. The most efficient use of development resources
will address all three issues simultaneously. For some examples: decentralized renewable
energy addresses energy poverty, reduces greenhouse gas emissions, and enhances
resilience of poor communities (Venema and Rehman 2007); improved water and waste
management services improve resilience while avoiding emissions from untreated
decomposition; and slum upgrading from dangerous areas to safe, energy efficient homes
reduces emissions and vulnerabilities to extreme events. Current development plans in each
city begin to address these issues. Further recommendations of specific strategies that will
address mitigation, adaptation, and development are provided for each city.
Officials in Amman have been working to improve urban life for a number of decades. In the
1980s, the city introduced housing upgrading programs that legalized land tenure in
squatter settlements and built household connections to water, sewage, and electricity
infrastructure (Bisharat and Tewfik 1985). The upgrades made the settlements less prone to
washout and lessened safety and health risks. Today, authorities are continually addressing
the problem of water scarcity, approaching the issue from multiple angles including water
management infrastructure projects (GTZ 2004) and public-private partnerships (Gerlach
and Franceys 2009). Recently, some of the most significant projects have focused on the
city’s social fabric: sidewalks, park benches, and pedestrian walkways with trees are
67
improving infrastructure resiliency and quality of life while “tearing down walls between rich
and poor” (Stockman 2010). Mobility is increasingly important for the young population, and
creating connectivity and curbing sprawl are top priorities.
The greatest contributor to the GHG inventory in Amman is the electricity sector, and the
greatest climate vulnerability is the water supply. The latter issue exacerbates the former:
the electricity consumption for water pumping is already high, and it will grow with climate
change. Therefore, a recommendation strategy for climate change mitigation, adaptation,
and service provision in Amman is an increased share of photovoltaic electricity production,
especially for energy needs surrounding water supply. Amman receives a high amount of
solar radiation each year (20.4 MJ/m2; see Figure 7), making photovoltaic electricity a
viable renewable energy option. Water technologies, such as deep groundwater pumping or
desalination, are very energy intensive, and meeting those energy needs in a resilient,
carbon neutral manner is essential.
In Jakarta, the tradition of community-based development is also applied in response to
climate change (see Karamoy and Dias 1986). The municipal government is working with
communities on disaster preparedness and budget management programs, as well as water
treatment, waste management, and waste-to-energy programs that are currently in
progress (Bowo 2010). Some major successes in Jakarta have been the conversion of users
of kerosene to LPG, car free days, emissions testing for cars, expansion of green spaces,
and plans to shift public transportation to alternate fuels (Bowo 2010). Not only do these
efforts reduce emissions, they also improve the resilience of Jakarta’s communities:
diversity in energy sources reduces vulnerability to energy infrastructure disruption and
shortages, and increases in vegetation provide adaptive ecosystem services that improve
community life.
Jakarta’s highest emitting sectors are electricity and road transportation. The government’s
current work to enhance public transportation and reduce vehicle use targets greenhouse
gas emissions as well as local air pollution. However, one of the greatest areas of
vulnerability in Jakarta is flooding and sea-level rise, specifically for the urban poor living in
unsafe, flood-prone areas. A synergetic recommendation for Jakarta addressing mitigation,
adaptation, and development is advanced slum upgrading: relocation of the at-risk poor to
safe areas with energy efficient homes connected to public transit and decentralized,
community-based electricity generation. There are a variety of vernacular, Southeast Asian
architecture techniques that take advantage of passive day-lighting and ventilation
strategies. Combined with electricity produced nearby using renewable resources, the
68
resultant community would be more resilient to climate change with a minimal carbon
footprint.
The municipal government of Dar es Salaam has a number of programs that address
development and climate change mitigation. For example, the government has programs in
place to encourage waste-to-energy briquettes and cooking stoves (as an energy alternative
to charcoal), tree planting, methane flaring at the local dumpsite, as well as a planned Bus
Rapid Transit project (Kimbisa 2010). International development banks also have projects in
Dar es Salaam, such as the World Bank’s Community Infrastructure Upgrading Program
(CIUP) that has built roads with drainage systems, street lights, water kiosks, and solid
waste containers (World Bank 2002). These programs improve resiliency to flooding and
landslides, diversify energy resources, promote economic activity, and encourage waste
management.
The World Bank’s CIUP projects in Dar es Salaam are excellent ways to improve the
resiliency of poor communities to flooding. Building on this strategy, a recommendation for
Dar es Salaam focuses on community habits of waste disposal. Waste emissions are highest
in the city’s inventory, which only represents waste collected and disposed in landfills. The
waste left to decompose in the streets not only produces emissions, it also causes
contamination of the water supply and disease during floods. A synergetic way to address
this issue is to implement waste dumping practices combined with community-based waste-
to-energy facilities. This would reduce climate change impacts and vulnerabilities while
addressing energy poverty in poor communities.
Summary and Conclusions
The need to address climate change mitigation and adaptation simultaneously is quite
pronounced in developing cities. The strategies to manage and mitigate risks are
complementary: reducing emissions now will ensure climate change does not surpass a
level manageable by adaptation in the future. This is especially relevant for the urban poor,
for they will experience the effects of climate change most severely. Cities in developing
regions are faced with the tasks of carbon neutral development, climate change protection,
and increased service access for their citizens.
The cities presented in this paper are examples of three unique urban circumstances.
Amman has a young population with a primarily service-based economy; Jakarta is the
most population city in Indonesia with economic activity focusing on services, finance, and
69
manufacturing; and Dar es Salaam has a rapidly growing population and many support
themselves with small-scale entrepreneurship. The severity of the living conditions of the
urban poor varies, but an important commonality remains: the poor live in unplanned
developments with little access to municipal infrastructure, putting them highly at risk to
the extreme events associated with climate change.
On a global scale, climate change is considered to cause a variety of extreme events,
including flooding, droughts, sea-level rise, and intense storms. The population density and
prevalence of physical infrastructure makes cities particularly vulnerable. The climate
change vulnerabilities in the three study cities have the potential to drastically impact the
way of life of urban residents. In Amman, water scarcity is a problem that worsens each
year, and it will continue to as the region experiences a reduction in precipitation and an
increase in population. In Jakarta, flooding and sea-level rise have the potential to alter the
normal way of life. Alternating droughts and floods in Dar es Salaam challenge the resilience
of already fragile infrastructure. In all cases, the unplanned developments are at a
particularly high risk of experiencing the most devastating consequences.
A greenhouse gas inventory is the first step to effective emissions reduction strategies. The
GHG inventories for the three study cities were conducted according to a city-scaled version
of IPCC methodology, revealing the following: Amman was responsible for 10.3 megatonnes
of greenhouse gases, Jakarta for 44.6 megatonnes, and Dar es Salaam for 1.6 megatonnes.
The sectors responsible for the highest percentage of emissions in the three cities were
generally road transportation, electricity generation, and waste. This pattern raises an issue
that warrants further investigation: the highest emissions result from services and
infrastructure that are typically inaccessible to the urban poor. The local distribution of
emissions sources could be a useful element in future development planning.
In all three cities studied, an aggressive reduction in greenhouse gas emissions will need to
target the lifestyles of the rich; nevertheless, climate change adaptation and access to basic
services remain priorities for the poor. Strategies that address mitigation, adaptation, and
development together will be the most effective in cities in developing regions. Officials in
Amman, Jakarta, and Dar es Salaam have recognized the importance of including climate
change in their development strategies, and they are implementing projects that address
both climate change and the development needs of their residents. A recommendation of a
synergetic climate change strategy was made for each city. For Amman, solar energy has
the potential to meet many electricity needs, particularly those related to water pumping.
The relocation of the poor from unsafe areas is a top priority in Jakarta, and alternative
70
housing could be met with energy efficient homes connected to transit and community-
generated electricity. In Dar es Salaam, upgrading the waste collection in unplanned
settlements and using the waste to produce energy locally is a potential solution to both
waste dumping and energy poverty. In all three recommendations, key adaptive
requirements have been addressed along with heavy emitting sectors. Similar synergic
approaches could be developed for other cities as well.
In developed and developing regions of the world, it is increasingly important for cities to
address climate change mitigation and adaptation as part of their strategic development
plans. All cities are unique in their infrastructure, municipal priorities, and social fabric;
therefore, local involvement in research and assessment is crucial. Sustainable development
requires not only an understanding of climate change science, but also leadership that
encourages creativity and innovation in project implementation. Perhaps most importantly,
it will be essential for cities to disseminate their experiences, allowing cities to learn from
each other and explore new ideas.

Chapter 5 Moving Forward
Each of the three papers in this thesis provides a unique urban perspective on the response
to climate change. “Greenhouse Gas Emissions from Chinese Cities” illustrates the situation
in China, where urbanization is rapid and the economy is extremely carbon intensive. The
case in an established, developed city that is starting to take steps to reduce emissions is
shown in “A Low-Carbon Infrastructure Plan for Toronto, Canada.” Finally, the challenges
experienced in developing cities, where poverty is a chief concern, are depicted in
“Synergies between Adaptation and Mitigation in Development: Case Studies of Amman,
Jakarta, and Dar es Salaam.”
While the perspectives in the papers are unique, three commonalities tie them together.
They illustrate three important and interconnected processes: economic growth,
infrastructure development, and the response to climate change. The early stages of
economic growth are shown in Amman, Jakarta, and Dar es Salaam, followed by an
economy in transition illustrated by Chinese cities, then finally an established economy
shown in Toronto. The infrastructure development priorities vary accordingly: basic access
to services is paramount in Amman, Jakarta, and Dar es Salaam; rapid infrastructure
construction corresponding to accelerated urbanization is the case in Chinese cities; and in
Toronto the priority is strategic infrastructure enhancement. The climate change response
process, from conducting assessment of climate change impacts (i.e. a greenhouse gas
inventory) or vulnerabilities to strategic planning for mitigation or adaptation, can be
followed through the papers.
The overall picture presented by the three papers is one of diversity. The cities presented
face unique challenges when it comes to climate change, as do cities throughout the world.
However, if responses to climate change are to be efficient and effective, cities around the
world must learn from the unique circumstances and best practices of other cities. Cities
must respond to climate change at various scales and adopt different financial mechanisms
to do so. As the response process to climate change moves forward, these issues will
become increasingly important targets of innovation.
74
Comparison and Dissemination
Disseminating experiences and enabling cities to learn from each other requires a certain
amount of city to city comparison, which is not always favoured by city officials. Officials
often worry that comparison of their city to another may result in a competition of
“goodness”. While a certain amount of competition may drive change, when comparing
metrics from cities, such as per capita greenhouse gas emissions, it is important to
acknowledge the inherent differences captured in those values. Differing levels of
development, gross domestic products, physical geographies, political systems, economic
sectors, and population demographics will impact the level of emissions and the success of
strategic mitigation and adaptation projects in a city. Successful dissemination will come
from finding commonalities among these differences.
Interesting work addressing the issue of comparison and dissemination is that of Xuemei Bai
and colleagues (Bai et al. 2010). By comparing 30 innovative best practices in urban
sustainability in Asia, the authors were able to pinpoint the successes, barriers, and
necessary circumstances to maximize project success and transferability. In finding
commonalities among projects, issues of varying economic, social, and political
circumstances were able to be resolved. On-going analysis in Asia and other global regions
would be of great benefit to strategic planning, enabling prediction and promoting
successful project management.
Progress in the dissemination and comparison of urban responses to climate change will also
be manifested in terms of learning platform. Workshops, conferences, and publications are
the traditional methods of communication; however, the networking capabilities of the
internet are promoting new possibilities. Currently in progress, the Carbon Neutral City
Planner tool based on Getting to Carbon Neutral (Kennedy 2010) will be accessible as a
piece of online software, allowing planners and citizens to conduct various scenarios for low-
carbon development for Canadian cities. The strategies are based on the best practices of
others, but applied to the unique geographic circumstances of each city. A suggestion for
further work is a similar online platform for global cities (perhaps through the C40 or
another international group), where an analysis similar to that of Bai et al. (2010) is
conducted for numerous projects. This would provide urban planners and developers with
searchable listings of key commonalities for the success of different types of climate change
mitigation and adaptation projects.
75
Scale of Strategic Response
The strategic mitigation and adaptation responses to climate change presented in this thesis
highlight infrastructure and policy development, and these may occur at various spatial
scales. Strategies may target change at the level of the individual, the community or
neighbourhood, or the city as a whole. Strategies should be catered to the scale they
address, and multiple scales may be addressed at once to maximize the success of a
strategic response.
At the level of the individual, personal choice and lifestyle can impact greenhouse gas
emissions as well as vulnerability to climate change. People may choose to live energy-
intensive lifestyles, or they may be in a situation of poverty where they live in dangerous
squatter settlements. For example, in the developed city context the choices of the
individual play a very important role in climate change mitigation. An organization currently
addressing this is the Zerofootprint Foundation. (Zerofootprint 2010). Through social
networking and an online carbon calculator, Zerofootprint is creating software that brings
awareness to individuals of their greenhouse gas impact, and encourages them to work as
members of an online community to reduce emissions. As difficult as it is to mobilize
individuals, in democratic systems they have immense political and consumer power to
drive change.
The need to understand the climate change response on a neighbourhood level is another
area for further work, previously mentioned in the Chapter 4. The type and availability of
infrastructure varies most on the neighbourhood scale, resulting in varying levels of
greenhouse gas emissions and climate change vulnerabilities. The attribution of emissions
varies greatly by neighbourhood; for example, per-capita emissions in a high-rise complex
close to transit in Toronto are one tenth that of an isolated neighbourhood of single-family
homes in the suburbs (Hoornweg et al. 2011). Further research is needed, especially in
developing cities, to understand these neighbourhood differences and to encourage climate
change responses to be tailored appropriately.
Financial Mechanisms
One essential aspect of the climate change response that was not addressed in this thesis is
the costs and sources of funding for mitigation and adaptation strategies. While this topic is
beyond the scope of this thesis, it is important to mention in a holistic look at the responses
to climate change. Technology costs will vary over time, indicating that some strategies that
76
are not feasible now will be in the very near future. Financial mechanisms are an essential
area where future research is needed; financing will be a continuous source of innovation in
the response to climate change.
The development of carbon markets has supported the development of innovative financial
mechanisms for climate change mitigation strategies. Putting a price on carbon creates
costs associating with emitting greenhouse gas emissions. Therefore, in addition to savings
associated with reducing energy consumption, there are now monetary savings associated
with reducing emissions. Carbon finance and the Clean Development Mechanism have
enabled projects throughout developing countries. While the costs of technology will change
over time, a study of the capital costs and greenhouse gas reductions of various CDM
projects revealed that waste projects are currently the most efficient (Kennedy et al. 2010).
Additional innovative financial mechanisms are emerging in developing regions, such as the
work of Grameen Shakti (Grameen Shakti 2009) on the microfinance of decentralized
renewable energy projects.
The financial mechanisms associated with mitigation are enabled by one very important
characteristic: the amount of greenhouse gas emissions avoided by a project is a metric
that can be quantified. However, for adaptation no such metric exists yet. This is one area
where future research is desperately needed: for some cities, adaptation is a far more
pressing issue than mitigation. The development of a financial mechanism for adaptation,
similar to that of carbon markets for mitigation, will enable a more rapid uptake of the
adaptation strategies and projects that will save countless lives in some of the poorest
regions of the world.
Conclusions
The process of responding to climate change is dynamic, and it will continue to change over
time. The papers presented in this thesis provide a snapshot of the process, as it exists at
the time of publication, in different cities throughout the world. Topics covered include:
issues of assessing climate change impacts and responsibilities, including greenhouse gas
emissions inventories; strategic development scenarios that addressing climate change
mitigation; and the need to consider synergic development strategies for mitigation and
adaptation. The three papers point to one important conclusion: there is more work to be
done. We need to better understand how to enable cities to learn from each other, how to
target efforts at the appropriate scale, and how to finance necessary infrastructure
developments. The single most important driver of the future responses to climate change
77
will be innovation. Climate change will require us all to think differently about our
consumption habits and the nature of our economies; accordingly, we must think differently
about our cities. The fight against climate change will be won or lost in cities, and now is the
time for innovative action.

Notes on Table 2
i Electricity GHG intensity is based on the national electricity supply mix, including transmission and distribution losses.
Consumption is based on national per-capita urban electricity consumption.
ii All gasoline and diesel fuel was considered to be for road transportation, a 60-40 gasoline-diesel split by volume was taken;
emissions factors for mobile combustion were used.
iii All avgas and jet kerosene loaded onto planes at the airport were used, assumed to include domestic and international air travel;
emissions factors for mobile combustion were used.
iv Emissions factors were determined using IPCC defaults for waste composition.
