Air Pollution in Brunei
Brunei faces significant air pollution challenges. 100% of states exceed the WHO guideline for clean air. This is putting 477 thousand across 4 states at risk.
The average PM2.5 over 2023 was 8.9µg/m³. That's 1.8 times the WHO guideline for clean air of 5µg/m³.
This is equivalent of everybody, including children, smoking about 148 cigarettes in a year.
