Cleaner Air = Longer Lives


You can use this interactive map to find out how many extra years you could expect to live if your country met the World Health Organization's recommended safe levels of air quality. The Energy Policy Institute at the University of Chicago's Air Quality-Life Index map shows how many life years could be saved in countries around the world if they met WHO standards for safe levels of airborne particulate matter pollution.

The darker the color on the map then the more years could be saved. In other words the darkest areas have the worst records of air pollution. You can actually view particulate pollution concentrations on the map by switching to the 'Pollution' layer.


Air pollution causes 1 in 8 deaths worldwide. The World Health Organization's own interactive map, Global Ambient Air Pollution, also shows the levels of pollution across the globe. The map displays the average annual atmospheric particulate matter levels throughout most of the world. The data used is from the WHO Global Urban Ambient Air Pollution Database, which covers 3000 cities in 103 different countries.

The Global Ambient Air Pollution map helps highlight the fact that air pollution most effects those living in low and middle income countries. However 56% of cities in high-income countries also don't meet the WHO air quality guidelines. Even in high-income countries urban air pollution levels tend to be higher in low and middle-income cities and in the poorest neighborhoods of high-income cities.
