Only 13 countries and territories had ‘healthy’ air quality in 2022

Only 13 of the world’s countries and territories had “healthy” air quality last year, according to a new report, as air pollution surged to alarming levels in 2022.

The report by IQAir, a company that tracks air quality worldwide, found that average annual air pollution in roughly 90% of the countries and territories analyzed exceeded the World Health Organization’s air quality guidelines, which are designed to help governments craft regulations to protect public health. 

IQAir analyzed average air quality from 131 countries and territories, and found that just six countries — Australia, Estonia, Finland, Grenada, Iceland and New Zealand — and seven territories in the Pacific and Caribbean, including Guam and Puerto Rico, met the WHO air quality guidelines, which call for an average air pollution level of 5 micrograms per cubic meter or less.

Seven countries – Chad, Iraq, Pakistan, Bahrain, Bangladesh, Burkina Faso, Kuwait and India – had poor air quality that far exceeded the WHO guidelines with average air pollution over 50 micrograms per cubic meter.

The study looked specifically at fine particulate matter, or PM2.5, which is the tiniest pollutant but also the most dangerous. When inhaled, the PM2.5 travels deep into lung tissue where it can enter the bloodstream. It comes from sources like the combustion of fossil fuels, dust storms and wildfires, and has been linked to a number of health problems including asthma, heart disease and other respiratory illnesses.
