India, Pakistan and Bangladesh were among the countries with the worst air pollution, exceeding the guidelines by at least 10 times. The Scandinavian countries, Australia, Canada, Japan and United Kingdom ranked among the best countries for air quality, with average levels that exceeded the guidelines by 1 to 2 times. In the United States, IQAir found air pollution exceeded WHO guidelines by 2 to 3 times in 2021. “This report underscores the need for governments around the world to help reduce global air pollution,” Glory Dolphin Hammes, CEO of IQAir North America, told . “(Fine particulate matter) kills far too many people every year and governments need to set more stringent air quality national standards and explore better foreign policies that promote better air quality.” Above: IQAir analyzed average annual air quality for more than 6,000 cities and categorized them from best air quality, in blue (Meets WHO PM2.5 guildline) to worst, in purple (Exceeds WHO PM2.5 guideline by over 10 times). An interactive map is available from IQAir. It’s the first major global air quality report based on WHO’s new annual air pollution guidelines, which were updated in September 2021. The new guidelines halved the acceptable concentration of fine particulate matter — or PM 2.5 — from 10 down to 5 micrograms per cubic meter. PM 2.5 is the tiniest pollutant yet also among the most dangerous. When inhaled, it travels deep into lung tissue where it can enter the bloodstream. It comes from sources like the burning of fossil fuels, dust storms and wildfires, and has been linked to a number of health threats including asthma, heart disease and other respiratory illnesses. Allergy season will start much earlier than normal and be far more intense because of climate crisis, study suggests Millions of people die each year from air quality issues. In 2016, around 4.2 million premature deaths were associated with fine particulate matter, according to WHO. If the 2021 guidelines had been applied that year, WHO found there could have been nearly 3.3
