One-third of world population exposed to harmful air pollution: Monitor
Confirmed
In Short: The Copernicus Atmosphere Monitoring Service reports dangerous ozone levels affecting nearly 40% of the world's population due to extreme heat and human-caused pollution.
The Copernicus Atmosphere Monitoring Service (CAMS) has reported that nearly 40% of the global population has been exposed to dangerous levels of ground-level ozone this year, according to a new analysis of data from the first eight months of 2026.
This alarming statistic is a result of the combination of widespread extreme heat and human-caused air pollution, as detailed in a report by CAMS.
CAMS, which provides one of the most comprehensive assessments of Earth’s atmosphere, uses satellite data and advanced atmospheric modeling to monitor air pollution and wildfires globally.
The organization's analysis shows that 34% of the global population experienced ozone concentrations well above the World Health Organization’s recommended exposure levels between January 1 and September 15.
The Jharkhand High Court in India recently directed its state pollution control board to conduct surprise inspections and continuously monitor pollution data of two factories in Ramgarh to ensure compliance with air and water pollution limits.
In the Philippines, seven air monitoring stations across Manila recorded unhealthy levels of PM2.5 pollutants, following forecasts from the Copernicus Atmosphere Monitoring Service.
Meanwhile, Kuching, the capital of Malaysia’s Sarawak state, was named the world’s most polluted major city with air quality reaching hazardous levels.
The findings highlight the close link between climate change and air pollution, emphasizing the need for continuous monitoring and regulatory measures to address these issues.
What this adds
The report adds to the growing body of evidence linking climate change and air pollution, underscoring the importance of global monitoring and regulatory measures.
The sources have not established the exact geographical distribution of the affected population or the specific sources contributing to the ozone pollution.
