More than half of the world’s population lives in cities today. Over 99 per cent of large cities in low-income regions have air pollution levels that exceed World Health Organization (WHO) guidelines. Without concerted effort, air pollution in many cities will continue to worsen and the climate crisis will accelerate.

Our Campaign

Around the world, cities are committing to achieve WHO Air Quality Guidelines by 2030. Cities can play a key role in the fight against air pollution and the climate crisis by instituting policies and programmes to curb emissions and promote the use of clean energy.

Cities are joining forces with us through the BreatheLife Network, committing to act through the UN Clean Air Initiative and using networks like C40, ICLEI, World Resources Institute, World Wildlife Fund, Global Covenant of Mayors , Clean Air Asia, Clean Air Institute to drive action on practical solutions.

This year on 7 September – the fifth International Day of Clean Air for blue skies – find out about the air quality in your city and what actions your city can take to reduce air pollution.
