Hunan faces significant air pollution challenges. 100% of districts exceed the WHO guideline for clean air. This is putting 69.7 million across 14 districts at risk.
The average PM2.5 over 2023 was 28.4µg/m³. That's 5.7 times the WHO guideline for clean air of 5µg/m³.
This is equivalent of everybody, including children, smoking about 471 cigarettes in a year.
If Hunan met the WHO guideline of 5 µg/m³, the average person would live 2.3 years longer.
That's 160.2M years of life stolen from 69.7 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 10 most polluted districts in Hunan. 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.
