Air pollution is the world’s fourth leading cause of disease and death. The World Health Organization (WHO) estimates that 91% of the world’s population resides in places where annual mean air-pollution levels exceed the WHO guideline level of 10 μg per cubic millimeter.The GBD study estimated that air pollution was responsible for 6.7 million deaths (95% confidence interval [CI], 5.9 to 7.5 million) worldwide in 2019.1,2 Of these deaths, 4.1 million (95% CI, 3.5 to 4.8 million) were due to ambient air pollution and 2.3 million (95% CI, 1.6 to 3.1 million) to household air pollution. Other estimates, which are based on alternative exposure measures and newer exposure–response functions, suggest that air pollution may be responsible for as many as 9 to 12 million deaths annually.
