Our vision for future cities.

Urban ReLeaf believes in empowering vulnerable communities to shape climate change mitigation and green infrastructure actions in their neighbourhoods. Citizens in six cities across Europe are taking part in data collection campaigns on heat stress, humidity and air quality to improve the quality of life in their districts.

Comprehensive and reliable urban data ecosystems will allow policy-makers to develop more effective, tailored, city-specific strategies in the fight against climate change. Together, these can strengthen our cities, making them more resilient, liveable, and accessible for all.
