10 community champions cleaning their cities’ air

Across the world, city residents are powering action to tackle air pollution. Our 2025 Urban Clean Air Champions embody the creativity, courage, and persistence it takes to clean our air and create healthier cities for all.

Air pollution is the biggest environmental threat to human health, and a major driver of climate change, especially in cities. With 68% of the world’s population expected to live in cities by 2050, urban air quality is a growing problem that requires local solutions.

Despite the scale of the challenge, inspiring individuals are stepping up to improve air quality in cities around the world. These changemakers are already shaping healthier lives and more sustainable cities for communities.

Clean Air Fund supports diverse organisations and people tackling urban air pollution. Ahead of International Day of Clean Air for Blue Skies, we are proud to celebrate 10 Urban Clean Air Champions. By harnessing data and evidence, mobilising communities, influencing decision-makers, and fighting for inclusive measures, they prove that local leadership is at the heart of the movement for clean air.
