A unique index• Provides a complete set of 30 comparable indicators for all cities, with aggregated scores for each

• Based on transparent methodology

• Covers all main official or business capitals, rather than only on an opt-in basis

• Independently researched by Economist Intelligence Unit, with input from numerous sustainability experts

Page 6: Press Conference Green City Index: Agenda - Siemens · Press Conference Green City Index: Agenda ... The Economist Intelligence Unit (EIU) ... Slide 28 June 10,

The cities

Page 7: Press Conference Green City Index: Agenda - Siemens · Press Conference Green City Index: Agenda ... The Economist Intelligence Unit (EIU) ... Slide 28 June 10,

• Nearly all cities have lower CO2 emissions per head than the overall EU27 average of 8.46 tonnes. The 30-city average is also well below the average, at 5.21 tonnes.

• 23 out of 30 cities have a CO2 reduction target of some kind, separate from any national target. Of these, 15 have a concrete, city-specific action plan in place to support this. The average CO2 reduction target to 2020, across the 30 cities, is about 15%.

• Nearly all cities have signed up to participate in the Covenant of Mayors.

• More than half of all citizens in these cities (62.5%) either walk, cycle or take public transport to commute to work. Two thirds of all cities actively promote public awareness around green modes of transport.

• The average municipal waste per head generated each year across these cities is 511 kg, slightly better than the EU average of 522 kg. By contrast, the US average is 760 kg and Australia is 690 kg.

• 24 cities have implemented measures to reduce the amount of waste they produce.

Europe’s cities: by no means average

Page 8: Press Conference Green City Index: Agenda - Siemens · Press Conference Green City Index: Agenda ... The Economist Intelligence Unit (EIU) ... Slide 28 June 10,

• An average of slightly more than one in three residents drive to work across these 30 cities, contributing to increased CO2 emissions and general air pollution.

• The average proportion of renewable energy consumed is just 7.3%, a long way short of the EU’s stated goal of increasing the share of renewable energy usage to 20% by 2020.

• Just 14 of the 30 cities actively promote green energy usage through low or no taxes, subsidies or regulations.

• Nearly one in four litres of water consumed by cities is lost through leakage.

• Less than one fifth of overall waste is currently recycled.

But still work to be done

The overall rankings

Page 10: Press Conference Green City Index: Agenda - Siemens · Press Conference Green City Index: Agenda ... The Economist Intelligence Unit (EIU) ... Slide 28 June 10,

Big spenders• Index shows a strong positive correlation between wealth and environmental performance

• Nine of the top 10 cities in index are “wealthy” (ie, have GDP per head above €31,000)

• There are some worthy exceptions though: middle- income Berlin still manages to come joint first in the buildings category

Page 11: Press Conference Green City Index: Agenda - Siemens · Press Conference Green City Index: Agenda ... The Economist Intelligence Unit (EIU) ... Slide 28 June 10,

Examples from the West

• West European cities dominate the top half of the index, due in part to their longer history of environmental awareness

• Western cities also have the advantage in terms of the financial resources they can devote to green efforts

• Citizens are by and large kept fairly well-informed about environmental matters, and are very involved on a civic level

Page 12: Press Conference Green City Index: Agenda - Siemens · Press Conference Green City Index: Agenda ... The Economist Intelligence Unit (EIU) ... Slide 28 June 10,

Promise from the East

• All east European cities have incomes of less than €21,000 per head, putting them at the bottom half of the index in terms of wealth

• East European cities face challenges of historical legacy, from poorly insulated mass housing to highly polluting heavy industry

• Citizens, understandably, also have significant pent-up aspirations, some of which cause conflict with green goals

Page 13: Press Conference Green City Index: Agenda - Siemens · Press Conference Green City Index: Agenda ... The Economist Intelligence Unit (EIU) ... Slide 28 June 10,

Civic duties make for greener cities• Cities with an active civil society perform well in the index

• A comparison with other studies shows a strong correlation between voluntary civil participation and environmental performance

• Prior studies have confirmed this point (eg, installing insulation in old homes in London)

Siemens has been active in e-cars since 1882

The Elektromote was followed in 1905 by the Electric Victoria which rolled through Berlin as a taxi and delivery vehicle at a top speed of 24 kilometers per hour.

Werner Siemens drove the Elektromote – an electrically powered carriage – along a 540-meter test track in Halensee near Berlin.Siemens’ invention was not only the first electric vehicle, but also the world’s first trolley bus.

1905: “Electric Victoria”

1882: “Elektromote”

x2009: “Greenster”

The eRUF Greenster prototype, based on a Porsche, has a central motor with a capacity of 270 kilowatts (nearly 370 PS) and 950 Nm, and has an average range of around 200 kilometers.

Global change gives momentum for E- Mobility

1. Need for individual mobility is global

2. Energy needs are growing globally especially in developing countries.

3. Both requirements have been satisfied by fossil fuel like coal, gas and oil.

4. Climate change and shortage of fossil fuels motivates energy sector to invest more into renewable and CO2 technologies like sun and wind.

E – Mobility has three major advantages for the Eco- and Energy Systems:

1. Environmentally friendly production of electric energy for mobility and transport

2. E-Cars could serve as a intermediate buffer for peak energy of renewable

3. The overall efficiency of a EV is up to 90% where as ICE drive trains have up to 30%

2009 Siemens continues to apply and develop expertise on E-Drives, and V2G interfaces, e.g:

Porsche Greenster with RUF Automobiles and charging infrastructure - EDISON.

2020 Siemens estimates up 4 Million EV on German roads.

Siemens Belgium-Luxembourg

Major cities’ authorities face enormous infrastructure challenges

Population

Since 2007, more than 50% of the world's population live in urban areas.

Economy 20% of the world‘s GDP is generated in 10 economically most important cities.

Energy consumption

Cities account for ~75% of the world's energy consumption. Buildings account for :~40% of energy consumption

: 21% of CO2 emissions in Europe.

Environment

Cities account for ~ 80% of greenhouse gas emissions.

Page 46: Press Conference Green City Index: Agenda - Siemens · Press Conference Green City Index: Agenda ... The Economist Intelligence Unit (EIU) ... Slide 28 June 10,

Brussels will not escape the Megacities’ challengesThe population grows by more than 1% each year on average, more than twice the growth rate of the national Belgian population.

Economy

Brussels accounts for 20% of the national GDP.

Transport

60% of Brussels’ inhabitants travel mainly by car, on short distances, with an average 1,2 passenger per car.

Which are the consequences for the environment and the quality of

living of Brussels’ inhabitants?

Page 47: Press Conference Green City Index: Agenda - Siemens · Press Conference Green City Index: Agenda ... The Economist Intelligence Unit (EIU) ... Slide 28 June 10,

Siemens Belgium-Luxembourg

The Region and City of Brussels have well-established policies to tackle these challenges…

The Air Climate plan aims at cutting CO2 emissions by 15% between 1999 and 2010, through initiatives in the areas of transport, energy, enterprises and private households such as :

Increase in the offer of public transportation

Car parking policy

Transport plans for companies

Encourage clean vehicles

Traffic management

Better information of citizens on energy consumption.

Better insulation of buildings.

Better efficiency of heating installations.

Page 47

In particular :

Page 48: Press Conference Green City Index: Agenda - Siemens · Press Conference Green City Index: Agenda ... The Economist Intelligence Unit (EIU) ... Slide 28 June 10,

Siemens Belgium-Luxembourg

…and this delivers results

• Brussels ranked 9th among 30 EU cities surveyed by the EU Green City Index*.

But air quality, transport and energy consumption remain central issues

Air quality “Brussels ranks 16th for air quality. Transport accounts for 80% of carbon monoxide emissions and 77% of nitrogen oxide emissions. The heating of buildings accounts for 25% of sulphur dioxide emissions.”*

Energy“Brussels ranks 8th (among 30) for energy, and is set back primarily by its relatively poor performance on energy consumption and use of renewables. Brussels ranks 12th for buildings. Its score is pulled down by the high energy consumption of its residential buildings.”*

02 How to reduce city energy consumption? Reuse tram or metro breaking energy

Up to 40% of the energy provided to a tramway or a metro can be regenerated.

In Cologne, the energy produced when a tram breaks is stored and reused when another tram starts. This Siemens installation allows energy savings of 340,000 kWh (equivalent to a reduction in CO2 emissions of 370 tons / year)

> ULB and VUB are currently studying the conditions in which such a system could be deployed in Brussels’ city center.

03 How to make public service vehicles friendlier? Hybrid Drives reduces noise and energy consumption

The ELFA Hybrid Drive system answers the increasing demand for electrically powered city buses. It is a universal solution that can be applied to many different vehicles (buses, dustcarts…).

The fuel cell generates the basic energy supply while the batteries make it possible to recover the energy that is released during braking or to give that extra energy boost required when the vehicle needs to accelerate.

This results in less noisy and more energy-efficient public service vehicles.

04 How to reduce Brussels’ buildings energy consumption?

The most efficient levers are not always the most obviousEfficient heating, appliances and lighting can save more CO2 at a lower cost than pure insulation.

04 Siemens’ energy audits help identify the right levers before deciding on investment

> Siemens carries out energy audits which identify the most efficient levers to reduce energy consumption and their feasibility.

Based on these studies, projects can be launched with contractual targets in energy consumption reduction.

For example, Siemens energy management solutions allowed the Aalst General Hospital to save more than 30% on its energy bills.

Overall, Siemens updated more than 7,500 buildings with the latest energy saving technologies, achieving €2 bn savings for customers and saving 1,2 million tons of CO2 (equivalent to the emissions of 6,000,000,000 km of car use).

06 How to prepare our electric infrastructure to more solar electricity…

Solar electricity generation is booming, including in city areas. • But the sun does not always shine when electricity is most needed. • And today’s electrical networks are built for unidirectional flow from one

producer to various consumers, and not for a network of various intertwined producers and consumers.

Page 61

> On the medium term, a new electrical infrastructure (‘Smart Grid’) capable of managing bidirectional energy flows and of storing excess energy will be needed.

06 …and prepare our electric infrastructure to the arrival of electric cars?

Charging stations for low noise and low emissions electric cars would need massive adaptations of the grid.

And the batteries of e-cars could be part of the Smart Grid as a solution to store excess energy during high production hours and to release it in peak consumption times.

Page 62

> Siemens can help make the distribution grid smarter thanks to solutions that help distribution grid operators better integrate decentralized energy sources.
