HEI’s Global Health program has released two new special reports that provide detailed data on air quality for every country in the world, as measured against the WHO’s new Air Quality Guidelines, released in September 2021. Currently, no country in the world meets the new annual guideline of 5µg/m3 for ambient PM2.5. Further, fewer than half of the world’s countries meet the least stringent interim target of 35µg/m3. One report details that life expectancy impacts from exposure to air pollution can be profound, cutting average global life expectancy by nearly two years. Global regions and countries with the highest levels of air pollution would benefit the most from pollution reductions, with even small reductions in air pollution providing health benefits and improved life expectancy.
Read the reports, How Does Your Air Measure Up Against the WHO Air Quality Guidelines? And How Does Air Pollution Affect Life Expectancy Around the World? Comprehensive interactive maps and data are available at HEI’s State of Global Air website.
