Air Pollution in Thimphu

Thimphu faces significant air pollution challenges. 100% of districts exceed the WHO guideline for clean air. This is putting 166 thousand across 8 districts at risk.

The average PM2.5 over 2023 was 22.4µg/m³. That's 4.5 times the WHO guideline for clean air of 5µg/m³.

This is equivalent of everybody, including children, smoking about 372 cigarettes in a year.

Air Quality Trend

Annual PM2.5 levels from 2014 to 2023. The WHO guideline for safe air is 5 µg/m³.

Life Expectancy Impact

If Thimphu met the WHO guideline of 5 µg/m³, the average person would live 1.74 years longer.

That's 289K years of life stolen from 166 thousand people. Years of watching children grow up. Years of building a career. Years of quiet mornings and celebrations.

Lives cut short. Breathing kills.
