Mortality from air pollution: WHO estimates 3.7 million deaths can be attributed to ambient (outdoor) air pollution in 2012. Approximately 88% of those deaths occur in low- and middle-income countries, with the greatest burden falling in the Western Pacific and South East Asian WHO regions. In 2012, 4.3 million deaths were triggered by household (indoor) air pollution. Almost all these deaths occurred in low- and middle-income countries. All together, air pollution is responsible for about 1 in 8 deaths worldwide.
