WHO says 99% of world’s population breathes poor-quality air

The UN health agency says nearly everybody in the world breathes air that doesn’t meet its standards for air quality, calling for more action to reduce fossil-fuel use, which generates pollutants that cause respiratory and blood-flow problems and lead to millions of preventable deaths each year.

The World Health Organization, about six months after tightening its guidelines on air quality, on Monday issued an update to its database on air quality that draws on information from a growing number of cities, towns, and villages across the globe — now totalling over 6,000 municipalities.

WHO said 99% of the global population breathes air that exceeds its air-quality limits and is often rife with particles that can penetrate deep into the lungs, enter the veins and arteries, and cause disease. Air quality is poorest in WHO’s Eastern Mediterranean and Southeast Asia regions, followed by Africa, it said.

“After surviving a pandemic, it is unacceptable to still have 7 million preventable deaths and countless preventable lost years of good health due to air pollution,” said Dr Maria Neira, head of WHO’s department of environment, climate change and health. “Yet too many investments are still being sunk into a polluted environment rather than in clean, healthy air.”
