Current Focus Areas

Green Space

Urban Canopy Programme

Increasing tree cover in dense urban areas by 15% before 2030. Working with municipal planners to identify heat islands and prioritise planting.

Mobility

Safe Cycling Network

Designing protected cycling infrastructure for mid-sized European cities. Focus on school routes, commuter corridors, and last-mile connections to public transport.

Air Quality

Low-Emission Zones

Technical support for cities implementing LEZ policies. Sensor deployment, data analysis, and citizen communication strategies.

Impact in Numbers

Trees Planted

Over 28,000 trees planted across 12 cities since 2020. Each site selected using satellite heat-mapping data to maximise cooling effect.

Cycling Infrastructure

142km of new protected cycle lanes designed and built. Measured 23% increase in cycling commuters in participating districts.

Air Quality

PM2.5 levels reduced by an average of 18% in LEZ pilot areas. 340 real-time air quality sensors deployed across partner cities.

"Clean City's approach is what makes them effective — they combine rigorous data analysis with practical, community-centred implementation. Their cycling network study changed how we plan transport infrastructure."

— Dr. Elena Vogt, City of Freiburg Urban Planning Department
