Siemréab faces significant air pollution challenges. 100% of districts exceed the WHO guideline for clean air. This is putting 1.1 million across 13 districts at risk.
The average PM2.5 over 2023 was 18µg/m³. That's 3.6 times the WHO guideline for clean air of 5µg/m³.
This is equivalent of everybody, including children, smoking about 299 cigarettes in a year.
If Siemréab met the WHO guideline of 5 µg/m³, the average person would live 1.28 years longer.
That's 1.4M years of life stolen from 1.1 million people. Years of watching children grow up. Years of building a career. Years of quiet mornings and celebrations.
