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.
