Why Covenant of Mayors? The cities have been working with the issues for a long time. A will to show what they do Not only members sign the covenant, 49 signatories in total.
First of all: Klimatkommuenrna = the Climate Municipalities = il clima Comuni An organisation of local governmenst in Sweden since 2003. High ambition in local climate action.
Green highway from coast to coast – 450 km (Napoli – Firenze) It's not just electricity but also about other renewable fuels. It is possible to fill biogas in Östersund and Sundsvall, E85 at about 20 places along the road, RME can you fill in Sundsvall and Trondheim. A total of nine charging stations was put up before the end of 2010, ie it should be possible to charge the electric car evergy 120 km.
Biogas as vehicle fuel Primarily as a treatment plant for waste from the food industry in Kristianstad. The Karpalund plant was the first in Sweden to co-digest municipal solid waste from households (sorted into paper bags) and food industry together with manure for production of useful energy and fertilizer. The project is a result of co-operation between the municipality, farmers, industry and consumers. The digestate from Karpalund is recycled as a bio-fertilizer and replaces chemical fertilizers. 40 000 MWh/year, which means that approx. 3,500 m3 oil or gasoline could be replaced and 9,500 tons of carbon dioxide could be saved. 30 buses are presently in operation, The total number of vehicles running on biogas in Kristianstad is about 250 2010.
District heating: Construction started in the fifties Today it’s over 1 000 km long. Enclosed tunnel and buried pipeline system Provides heating and hot water to more than 90 % of all apartment buildings and commercial premises. For the production of hot water in the district heating system, Göteborg Energi primarily uses waste heat from industries, power production and the incineration of waste. 80 % of the fuel mix for district heat production is waste heat. During the summer months no additional fuel is needed. More background Göteborg Energi produces most of the remaining heat in its own power plants. The fuel mainly used consists of different forms of bio-fuel and natural gas. The long term goal is to only use fully renewable energy sources. Over the past four decades CO2 emissions decreased by over 90 % (per unit of district heating produced). Overall, Göteborg Energi’s district heating system supplies over 60% of the Gothenburg residents with heat and hot water. Picture The picture is not of district heating pipes, but of the similar looking district cooling pipes. In the mid-1990s we started selling district cooling to our customers. Cooling was initially supplied to customers from several small refrigeration plants. For the past few years, cooling has been produced by the Rosenlund plant using free cooling, collected from the cold water of Göta river, supplemented by absorption cooling. Absorption is a process which uses waste heat from inter alia waste incineration and refineries during the summer months to convert heat to cooling. The method is extremely reliable and environmentally correct, since it saves electricity and minimizes noise.
An energy analysis of 240 properties in stock was made in order to identify needs and potential savings. 101 buildings with an area of 300 000 square meters were selectedfor the energy project. An action plan for each building was made. Examples of actions: Upgrading the heating and ventilationsystems and change of control, monitoring and measuring equipment. Oil boilers have been replaced with heat pumps and pellet or biofuel plants. Energy-saving lighting, showers and potable water have been installed.
Malmö is in the fore front when it comes to serving organic food in schools. In 2008 43 % of everything served was organic. The target for 2012 is 100 %, some schools are already there.
