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.

Latest from the Toolbox
The combination of district heating and heat pumps are foreseen to have a key role in the future district heating systems. This article looks at the integration of large-scale heat pumps in district heating, which can help balancing the power grid when the production of electricity from intermittent renewable energy sources fluctuates.
This study is investigating how Swedish energy prices are influenced by the owner of the energy network – a private or a municipal company.
Alexandroupolis, a seaside municipality in Greece’s northeast coast is going to have cost-effective geothermal energy and heating soon. As...

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.
