Air pollution is cutting short the lives of billions of people by up to six years, according to a new report, making it a far greater killer than smoking, car crashes or HIV/Aids.

Coal burning is the principal culprit, the researchers said, and India is worst affected, with the average citizen dying six years early. China has slashed air pollution in the last seven years, but dirty air is still cutting 2.6 years from its people’s lifespan.

Fossil fuel burning is causing air pollution and the climate crisis, but nations have much greater power to cut dirty air within their own borders. The climate crisis is now also adding to air pollution by driving wildfires, completing a vicious circle, the scientists said.

The team said recent events had illustrated the different futures possible depending on whether governments act or not. Coronavirus lockdowns cut pollution, revealing the Himalayas to some Indian city dwellers, while wildfires in the western US caused serious pollution on the other side of the continent in New York City.

“Air pollution is the greatest external threat to human health on the planet, and that is not widely recognised, or not recognised with the force and vigour that one might expect,” said Prof Michael Greenstone at the University of Chicago. Greenstone and colleagues developed the Air Quality Life Index (AQLI), which converts air pollution levels into their impact on life expectancy.

The average global citizen loses 2.2 years of life with today’s levels of air pollution and, if nothing changes, that adds up to 17bn lost years, Greenstone said. “What else on the planet is causing people to lose 17bn years of life?”

“Furthermore, we’re not just letting it happen, we’re actually causing it,” he said. “The most striking thing is that there are big countries where, effectively, a combination of the government and [societal] norms are choosing to allow people to live really dramatically shorter and sicker lives.” He said switching to cleaner energy and enforcing air quality measures on existing power plants have cut pollution in many countries.

The report estimated the number of additional years of life people would gain if air pollution levels in their country were reduced to World Health Organization guidelines. In India, the figure is 5.9 years – in the north of the country 480 million people breathe pollution that is 10 times higher than anywhere else in the world, the scientists said. Cutting pollution would add 5.4 years in Bangladesh and Nepal, and 3.9 years in Pakistan.
