Welcome to the Celsius Initiative!
We are a demand driven collaboration hub for efficient, integrated heating and cooling solutions supporting cities in their energy transition to carbon-neutral systems. Focusing on cities’ needs, through the forerunner groups, it connects its members to exchange on climate and environmental policies, foster innovation, leading to solutions that accelerate sustainable development in Europe and across the world.
The initiative also provides continuous knowledge sharing through a monthly newsletter, webinars, participatory workshops and the Celsius Toolbox. The later gathers and shares technical, economic, social and policy expertise.

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.
