In 2022, only 5% of countries met the annual air pollution thresholds set by the World Health Organization, according to estimates by the Swiss company IQAir. So which countries are breathing the most polluted air?

Around 90% of the world’s population is affected by air pollution, according to the World Health Organization (WHO). Exposure to fine particles (PM2.5) remains one of the greatest health threats to humanity, “with the impact on life expectancy comparable to that of smoking, more than three times that of alcohol use and unsafe water, and more than five times that of transport injuries like car crashes,” according to research conducted by the Energy Policy Institute at the University of Chicago and published in August.
