Research finds shows only seven countries meet WHO air quality standard

A new report has found that only seven countries are meeting an international air quality standard, with deadly air pollution worsening in places due to a rebound in economic activity and the toxic impact of wildfire smoke.

Out of the 134 countries and regions surveyed in the report, only seven – Australia, Estonia, Finland, Grenada, Iceland, Mauritius and New Zealand – are meeting a World Health Organization (WHO) guideline limit for tiny airborne particles expelled by cars, trucks and industrial processes.

According to the report by IQAir, a Swiss air quality organization that draws data from more than 30,000 monitoring stations around the world, the vast majority of countries are failing to meet this standard for PM2.5, a type of microscopic speck of soot less than the width of a human hair that when inhaled can cause a myriad of health problems and deaths, risking serious implications for people.

While the world’s air is generally much cleaner than it was in much of the past century, there are still places where the pollution levels are particularly dangerous. The most polluted country, Pakistan, has PM2.5 levels more than 14 times higher than the WHO standard, the IQAir report found, with India, Tajikistan and Burkina Faso the next most polluted countries.

But even in wealthy and fast-developing countries, progress in cutting air pollution is under threat. Canada, long considered as having some of the cleanest air in the western world, became the worst for PM2.5 last year due to record wildfires that ravaged the country, sending toxic smoke spewing across the country and into the US.

Meanwhile, In China, improvements in air quality were complicated last year by a rebound in economic activity in the wake of the Covid-19 pandemic, with the report finding a 6.5% increase in PM2.5 levels.

“Unfortunately things have gone backwards,” said Glory Dolphin Hammes, North America chief executive of IQAir. “The science is pretty clear about the impacts of air pollution and yet we are so accustomed to having a background level of pollution that’s too high to be healthy. We are not making adjustments fast enough.”

Air pollution kills an estimated 7 million people a year worldwide – more than Aids and malaria combined – and this burden is most heavily felt in developing countries that rely upon particularly dirty fuels for heating, light and indoor cooking.
