Three Decades of Air Pollution
With data going back to 1990, we analyze exposure to three types of air pollution — outdoor fine particulate matter (PM2.5), ozone, and household air pollution (HAP).
Exposure to fine-particle outdoor pollution remains persistently high in most places. More than half of the world's population lives in areas that do not even meet WHO's least-stringent air quality target.
