Phnom Penh faces significant air pollution challenges. 100% of districts exceed the WHO guideline for clean air. This is putting 2.5 million across 12 districts at risk.
The average PM2.5 over 2023 was 23.4Āµg/mĀ³. That's 4.7 times the WHO guideline for clean air of 5Āµg/mĀ³.
This is equivalent of everybody, including children, smoking about 388 cigarettes in a year.
If Phnom Penh met the WHO guideline of 5 Āµg/mĀ³, the average person would live 1.79 years longer.
That's 4.6M years of life stolen from 2.5 million people. Years of watching children grow up. Years of building a career. Years of quiet mornings and celebrations.
