50% deaths due to air pollution in 2017 from China, India: Report

Date: 04 April 2019 Tags: Miscellaneous

According to recent published State of Global Air report 2019, world’s two most populous countries -China and India together were responsible for half the total global attributable deaths from air pollution in 2017. The report was published by Boston-based Health Effects Institute (HEI).

Highlights of report

  • Long-term exposure to indoor and outdoor air pollution is estimated to have contributed to 4.9 million deaths across the world in 2017. China and India accounted for 1.2 million deaths each.
  • Ten countries with the highest mortality burden attributable to air pollution in 2017 were China (1.2 million), India (1.2 million), Pakistan (128,000), Indonesia (124,000), Bangladesh (123,000), Nigeria (114,000), US (108,000), Russia (99,000), Brazil (66,000) and Philippines (64,000).
  • Air pollution is responsible for more deaths across the world than any other risk factor including malnutrition, alcohol use and physical inactivity.
  • Air pollution collectively reduced life expectancy by 1 year, 8 months (20 months) on average worldwide. This means child born today will die 20 months sooner, on average, than would be expected in the absence of air pollution.
  • Long-term exposure to PM2.5 contributed to 2.9 million deaths in 2017, making PM2.5 exposure responsible for 5.2% of all global deaths.
  • The highest death burden was concentrated in China (8.52 lakh deaths) and India (6.73 lakh deaths), together accounted for 52% of total global PM2.5-attributable deaths.
  • Annual PM2.5 exposures were highest in South Asia, where Nepal, India, Bangladesh and Pakistan had the highest exposures. Bhutan was having lowest exposure level.
  • In South Asia, household air pollution contributes to additional life expectancy loss of about 1 year and 3 months, bringing total life expectancy loss from air pollution to 2 years and 6 months.
  • In sub-Saharan Africa, where more than 80% of people cook with solid fuels. Due to this household air pollution impacts life expectancy. It accounted for 1 year and 4 months of nearly 2 years in life expectancy loss from air pollution overall.
