Île-de-France faces significant air pollution challenges. 100% of districts exceed the WHO guideline for clean air. This is putting 12.5 million across 8 districts at risk.
The average PM2.5 over 2023 was 8.4µg/m³. That's 1.7 times the WHO guideline for clean air of 5µg/m³.
This is equivalent of everybody, including children, smoking about 139 cigarettes in a year.
If Île-de-France met the WHO guideline of 5 µg/m³, the average person would live 0.34 years longer.
That's 4.2M years of life stolen from 12.5 million people. Years of watching children grow up. Years of building a career. Years of quiet mornings and celebrations.
Lives cut short. Breathing kills.
The top 8 most polluted districts in Île-de-France. These areas face the greatest health burden from air pollution.
Distribution of population across different PM2.5 pollution levels. The WHO guideline is 5 µg/m³—only populations below this threshold are breathing safe air.
