Nan faces significant air pollution challenges. 100% of districts exceed the WHO guideline for clean air. This is putting 449 thousand across 15 districts at risk.
The average PM2.5 over 2023 was 35.4Āµg/mĀ³. That's 7.1 times the WHO guideline for clean air of 5Āµg/mĀ³.
This is equivalent of everybody, including children, smoking about 587 cigarettes in a year.
If Nan met the WHO guideline of 5 Āµg/mĀ³, the average person would live 2.98 years longer.
That's 1.3M years of life stolen from 449 thousand people. Years of watching children grow up. Years of building a career. Years of quiet mornings and celebrations.
