One Third Of World Population Exposed To High Ozone Pollution: Report

A report from the EU's Copernicus Climate Atmosphere Monitoring Service indicates that one-third of the global population was exposed to high ozone pollution in 2026. The rise in pollution is attributed to the intersection of climate change, record heatwaves, and increased wildfire activity.
Why it matters
It underscores the growing public health crisis caused by climate-driven air quality degradation, which transcends national borders.
Heatwaves and wildfires combined with human-caused emissions this year combined to expose one third of the world's population to extremely high levels of ozone pollution, a European Union report said on Wednesday.In a new analysis covering the first eight months of 2026, the European Union's Copernicus Climate Atmosphere Monitoring Service (CAMS) highlighted the close relationship between climate change and air pollution.When heat and sunlight react with airborne emissions from wildfires, vehicles and industry, they create ground-level ozone pollution, which can damage lung tissue, cause breathing problems, trigger asthma attacks and lead to other health issues.Despite progress in cutting the most harmful air pollutants in recent decades, ozone has proved more difficult to tackle as climate change fuels the conditions that favour its formation.This year's ozone pollution was driven in part by record-breaking heatwaves and wildfires that seared Europe and North America and sent smoke well beyond their borders.Indonesia has experienced…
