95% of the world's population or over 7 billion live in areas that exceed the WHO Guideline for PM2.5, says the State of Global Air 2018 report by the Health Effect Institute (HEI)

6.1 million people worldwide died in 2016 due to stroke, heart attack, lung cancer, and chronic lung disease, triggered by long-term exposure to outdoor and indoor air pollution. Of these, 4.1 million deaths occurred due to diseases linked to PM2.5 pollution while 2.6 million due to household pollution-related diseases

51% of the total global PM2.5-attributable deaths take place in India (25%) and China (26%)

1/3rd of the world's population living in the developing world faces a double burden of indoor and outdoor air pollution where exposures to both are high
