World’s worst polluted cities are in Asia - and 83 of them are in just one country

March 20, 2024

“We see that in every part of our lives that air pollution has an impact,” said IQAir Global CEO Frank Hammes. “And it typically, in some of the most polluted countries, is likely shaving off anywhere between three to six years of people’s lives. Central and South Asia were the worst performing regions globally, home to all four of the most polluted countries last year: Bangladesh, Pakistan, India and Tajikistan. South Asia is of particular concern, with 29 of the 30 most polluted cities in India, Pakistan or Bangladesh. One bright spot is increasing pressure and civic engagement from communities, NGOs, companies, and scientists to monitor air quality.
