All life forms on earth are carbon based. We are carbon based organisms too!
But… there are many of us and the world population is still growing.
Low-carbon cities: Investments in the transition process
- 50% of world population lives in cities.- Small and medium cities in developing countries are
growing fastest.- By 2050, two thirds of world population — 6.2 billion
people — may live urban lives.
Low-carbon cities: Investments in the transition process
Numbers
- 1 bln. of people lives presently in slums.- 100 mil. people are homeless.- By 2040 3 bln. of people (40% of the present
population) would be needing home.
The cities are going to GROW!

Numbers
Hence, we need to take action …. and we are doing that.

Definitions
Eco-cities
Cities built on the principle of living within environmental limits. Many eco-cities aim to eliminate all carbon emissions, produce energy entirely from renewable sources and generally to incorporate ‘green’ principles into city design. Cities with slightly less stringent aims may be described as ‘green’ cities.
Low-carbon cities
Cities focused on reducing their carbon footprint and keeping emissions as low as possible.
(Net) Zero-energy cities
Cities focused on producing the energy they need in a given year, resulting in net-zero energy use. Zero-energy cities have three main characteristics: incorporating maximum energy efficiency into the design of the entire city, generating energy on-site, and purchasing renewable energy produced off-site to meet any remaining energy needs.
Megacities: 10 million or moreLarge Cities: 5 to 10 millionMedium Cities: 1 to 5 millionSmall Cities: 500,000 to 1 million

Concepts and solutions (terms)
Existing strategies in Croatia that are either directly or in-directly related to mitigating climate change.
Low-carbon cities: Investments in the transition process
Croatia – Low emissions energy strategy (LEDS)
Implementation timeline: four defined periods
Low-carbon cities: Investments in the transition process
Croatia – Low emissions energy strategy (LEDS)
Towards the vision: Identified main measures > focus on Energy
Low-carbon cities: Investments in the transition process
Croatia – Low emissions energy strategy (LEDS)
- Increase in energy efficiency.- Increase of Renewable energy sources in Energy
mix.- Further use of fossil fuels in energy production with
CO2 caption and storage.- Building of energy storage facilities (i.e. RHPP).- Building and development of distributed energy
grids („Smart grids“).- Use of biofuels and electricity in transport and
traffic.

On the sideline: Energy
Global energy mix today:- Fossil fuels 82 % - same as it was 25 years ago
despite growing investments in renewables- Solar energy only 3% of global el. Energy
- 80% reduction of CO2 by 2020 to decrease the risk of irreversible changes to the climate.
- To reach „red line“ of 20 C global temperature increase we need only to emit new 565 gigatones of carbon into atmosphere.
- Global energy corporations presently „control“ reserves of 2795 gigatones worth 20.000 bln. $US!!!

Towards the low-carbon development vision
- The goal in essence is to establish zero balance between the emissions and imissions of GHG in order to avoid climate changes.
- Measures and actions have its reach and zero balance is for now very distant goal!
- Hence, direct carbon emissions offsetting concept was developed during the Kyoto period.

CASE 2. Passive house building
EPBD EU Directive on energy characteristics of buildings (2010/31/EU, EPBD)
nZEB = nearly Zero Energy Building = energetically highly efficient building that
uses renewable energy resources

CASE 2. Passive house building
INPUT: CEPH EU project 2008-2011
OUTPUT: SEEDpass project
South East Europe strategic partnership in vocational education and training in Passivhaus design for nearly zero energy buildings development.

CASE 3. Direct carbon emissions offsetting
- Global importance and impact- Two principal markets: compulsory (ETS) and voluntary (non-ETS)

In Croatia compulsory market is still not functioning yet but voluntary market is due to activities of one company only: CO2cut Ltd.

CASE 4. „Climate proofing” of projects in Cohesion funding in the Operational Program for the2014-2020 period
New for everybody in EU!
“It means that in the Feasability Study and Application it should be elaborated and explained how climate change related risks and adaptation considerations have been taken into account.”
