The State of Global Air 2025 report provides a comprehensive analysis of data for air quality and health impacts for countries around the world.
The analysis finds that:
- 36% of the world’s population is exposed to levels of PM2.5 pollution above the least stringent interim target of 35 μg/m3.
- About 1/3 – almost 2.6 billion people – are exposed to pollution from burning solid fuels for cooking at home.
- 95% of air pollution attributable deaths in adults over the age of 60 are due to noncommunicable diseases like COPD, dementia, diabetes, heart disease, and lung disease.
As in previous years, the State of Global Air 2025 report and accompanying website provides comprehensive data on the levels and trends in air quality and health for every country in the world.
This State of Global Air report was produced in partnership with IHME & NCD Alliance. In the State of Global Air 2025 interactive app, you can explore, compare, and download data and graphics reflecting the latest air pollution levels and associated burden of disease for over 200 individual countries, territories, and regions, as well as track trends from 1990 to 2023.
