The Aporia · One third of world population exposed to harmful air pollution: Monitor

A European Union report released on September 30 reveals that one-third of the world's population was exposed to extremely high levels of ozone pollution due to heatwaves and wildfires exacerbated by human-caused emissions in 2026. The Copernicus Climate Atmosphere Monitoring Service (CAMS) reported that 34% of the global population experienced “extremely poor” air quality, with concentrations well above the World Health Organization’s recommended levels of 100 micrograms per cubic meter over eight hours. Asia had the highest exposure rate, with 53% of its population breathing "extremely poor" air.

Story summary

PARIS - According to a report released on September 30 by the European Union’s Copernicus Climate Atmosphere Monitoring Service (CAMS), one third of the world's population was exposed to extremely high levels of ozone pollution in the first eight months of 2026. This exposure was exacerbated by heatwaves and wildfires, leading to human-caused emissions reacting with sunlight to form ground-level ozone, which can cause severe health issues like lung damage and asthma attacks.

While significant progress has been made in reducing harmful air pollutants over recent decades, tackling ozone pollution remains challenging due to its formation being favored by climate change. Major heatwaves and wildfires affected Europe and North America, sending smoke across borders, while Indonesia experienced substantial wildfires and a warming El Niño pattern was expected to peak later in 2026, potentially driving more fires in Southeast Asia.

Despite the widespread pollution issues, Oceania, including Australia and New Zealand, saw 66 percent of its population enjoying "good" ozone levels, with another 34 percent experiencing "fair" conditions. Overall, air quality was considered "good" or "fair" for 81% of South America's population during this period.
