Guide to European district heating projects

Get inspired and collect knowledge from innovative new projects financed by the European Commission. More then 60 innovation projects are being highlighted and presented with a focus on the replication potential in cities in this  overview.

​Give cities a voice in Brussels

No energy transition without sustainable cities; no sustainable cities without sustainable heating and cooling. As the 2016 European Commission’s Heating & Cooling Strategy made clear, district energy systems will have to play a significant role to make Europe’s broader climate and energy ambitions a reality. And cities will be in the driver’s seat to make a successful energy transition happen.
