The result from the study show that the introduction of district heating and cooling in combination with energy efficient buildings can decrease the overall green house gases with up to 18% in European cities until the year 2020. The model that the city of Linköping in Sweden uses today, with almost 100% district heating, results in a heating sector that is approximately 60% more energy efficient compared to the EU27-average, using a business as usual scenario until 2020. The overall outcome of the study is that action is needed both on the energy use and on the energy supply side. Neither one of the two perspectives is enough, if the cities' aspiration to achieve the 2020 target with 20% less green house gas emissions and energy use and 20% more renewable resources is to be reached in time................
