Reducing energy consumption and CO2 emissions in cities across Central Europe
Whilst cities cover only three percentage of Europe's surface, they account for eighty percent of the buildings and seventy five percent of carbon dioxide emissions. Therefore one of the major challenges faced by European countries today is the reduction of CO2 emissions that contribute to climate change. This is particularly true for cities as they account for eighty percent of the buildings and seventy five percent of carbon dioxide emissions. 
Buildings, whether commercial, residential, private or social housing, account for almost fifty per cent of energy use, with consequent impact on climate change and&nbsp; CO2 emissions. 

They are therefore an obvious area where efforts have to be concentrated as improvements in their energy efficiency can deliver substantial gains in the fight against climate change.&nbsp; All European countries are facing the same challenge to improve energy efficiency and reducing CO2 emissions, therefore a coordinated and transnational approach is needed in order to introduce coherent policies and achievable targets that can be met by all countries. 

The implementation of strategies in EnerCity for the reduction of energy consumption and the consequent increase of energy efficiency in buildings stocks and urban agglomerates will therefore contribute in an effective and direct way to the achievement of the fight against climate change.
