Climate Strategy 2012-2015 Mitigation

Climate strategy 2012-2015 Mitigation This part of the Climate Strategy 2012-15 is about Climate Mitigation and how the Muni- cipality of Aalborg through ambitious climate targets works towards being free of fossil fuels by 2050. This vision requires a broad approach on energy savings and renewable energy in the energy supply, in transport , industry and agriculture. 2 Aalborg Municipality Climate Strategy - Mitigation Introduction.............................................................................................................. 3 The global climate is changing 4 International and national climate goals 5 Greenhouse gas invetory 5 Aalborg Municipality and climate............................................................................. 6 Previous CO2 reduction efforts in Aalborg 6 CO2-Account for Aalborg 7 Towards a fossil free Aalborg 7 Vision and strategy for climate change mitigation.................................................. 8 Future targets for reducing greenhouse gases 8 How you read the climate strategy 9 Energy Vision 2050 10 Energy Strategy 2030 11 Energy conservation.............................................................................................. 12 Buildings 13 Businesses 14 Private households 14 The municipality as a company 15 Energy supply.......................................................................................................... 22 District heating 23 Biofuels 24 Geothermal heat 25 Wind turbines 26 Solar cells 27 Solar heat 27 Heath pumps 28 Cooling 29 Transport................................................................................................................ 30 Public transport 31 Cyclism/ cycling 32 Road transport 33 Environmentally friendly vehicles 34 Forestry.................................................................................................................. 36 Afforestation 36 Agriculture............................................................................................................. 37 Partnerships.......................................................................................................... 38 Climate education....................................................................................................39 Local Green Growth............................................................................................... 40 Implementating the strategy................................................................................. 41 Guidelines 42 New Initiatives 46 Inquiries 52 Aalborg Municipality Climate Strategy - Mitigation 3 The global climate is changing Climate change has always been a part of the earth’s natural development. “However, a broad scientific consensus has emerged that some of the observed climate changes are not a natural part of Earth’s development, but are man-made and partly due to emissions resulting from the use of fossil fuels such as coal, oil, and natural gas to produce heat and electricity and for transportation. ” However, a broad scientific consensus has degrees C, in the more pessimistic scenarios emerged that some of the observed climate temperatures are projected to rise by 4-6 changes are not a natural part of Earth’s de- degrees C. velopment, but are manmade and partly due to emissions resulting from the use of fossil Over 70% of global CO2 emissions come from fuels such as coal, oil, and natural gas to pro- cities because of population concentrati- duce heat and electricity and for transpor- ons and thus aggregate energy and material tation.

Climate researchers employ various scenarios of how the concentration of greenhouse gases in the atmosphere could develop over the next 100 years and thus how strong climate change will likely be. The scenarios are based on parameters such as global econo- mic development, population growth, and changes in technology. In the most favou- rable scenarios, average atmospheric global temperature increases will be around 2 4 Aalborg Municipality Climate Strategy - Mitigation International and national climate goals 37 countries have signed the UN Kyoto Pro- Denmark has ratified the Kyoto Protocol and tocol, which is a continuation of the United is obliged to reduce greenhouse gas emissi- Nations Frame-work on Climate Change (UN- ons by 21% on average over the period 2008 FCCC).
