Air Quality Index (AQI) Calculation The Air Quality Index is based on measurement of particulate matter (PM 2.5 and PM 10 ), Ozone (O 3 ), Nitrogen Dioxide (NO 2 ), Sulfur Dioxide (SO 2 ) and Carbon Monoxide (CO) emissions.

Air pollution is a health and environmental issue across all countries of the world but with large differences in severity. In the interactive map, we show death rates from air pollution across the world, measured as the number of deaths per 100,000 people in a given country or region.
The 2022 update (Fifth Version) database was released in April 2022 and hosts data on air quality for over 600 human settlements in more than 100 countries. The data compiled in this database is used as input to derive the Sustainable Development Goal Indicator 11.6.2, Air quality in cities, for which WHO is custodial agency.
This article published in the WHO bulletin in 2023, presents an overview of close to 50 years of WHO's activities in gathering air quality data and their use in global assessments and efforts to reduce health risks caused by air pollution.
WHO monitors the exposure levels and health impacts (i.e. deaths, DALYs) of air pollution at the national, regional and global level from ambient (outdoor) and household air pollution. Such estimates are used for official reporting like the world health statistics, and the Sustainable Development Goals.
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
Air pollution data of countries, regions and territories in the world. Compare real-time worldwide air quality levels with AirVisual's interactive air quality and pollution map. Learn from PM2.5 trends and our ranking of most polluted cities in the world.
