Air Pollution in Laos
Laos faces significant air pollution challenges. 100% of states exceed the WHO guideline for clean air. This is putting 7.9 million across 18 states at risk.
The average PM2.5 over 2023 was 28.9µg/m³. That's 5.8 times the WHO guideline for clean air of 5µg/m³.
This is equivalent of everybody, including children, smoking about 479 cigarettes in a year.
