Earth Day reminds us that the energy we use every day shapes the future of our planet.

Heating and cooling account for around half of Europe’s total energy consumption—yet many systems still rely heavily on fossil fuels.

That’s where the HEAT 35 project comes in.

By supporting cities and regions across Central Europe, HEAT 35 is driving the transition towards sustainable district heating systems—aiming for at least 50% renewable energy and waste heat by 2035. ()

Through collaboration with energy providers, public authorities, and experts, the project is developing practical tools, strategies, and a comprehensive HEAT 35 Kit to help modernise heating systems, improve energy efficiency, and reduce emissions. ()

This Earth Day, we highlight the importance of:
• decarbonising heating and cooling systems
• integrating renewable energy and waste heat
• strengthening energy resilience and security
• enabling a just and sustainable energy transition

Because transforming how we heat our homes and cities is essential for protecting our planet.

 

Happy Earth Day!
