Gansu faces significant air pollution challenges. 100% of districts exceed the WHO guideline for clean air. This is putting 27.1 million across 14 districts at risk.
The average PM2.5 over 2023 was 19.1µg/m³. That's 3.8 times the WHO guideline for clean air of 5µg/m³.
This is equivalent of everybody, including children, smoking about 317 cigarettes in a year.
If Gansu met the WHO guideline of 5 µg/m³, the average person would live 1.39 years longer.
That's 37.7M years of life stolen from 27.1 million people. Years of watching children grow up. Years of building a career. Years of quiet mornings and celebrations.
