Air Pollution in Kerala

Kerala faces significant air pollution challenges. 100% of districts exceed the WHO guideline for clean air. This is putting 34.8 million across 14 districts at risk.

The average PM2.5 over 2023 was 18.5µg/m³. That's 3.7 times the WHO guideline for clean air of 5µg/m³.

This is equivalent of everybody, including children, smoking about 307 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 Kerala met the WHO guideline of 5 µg/m³, the average person would live 1.32 years longer.

That's 46.0M years of life stolen from 34.8 million people. Years of watching children grow up. Years of building a career. Years of quiet mornings and celebrations.

Lives cut short. Breathing kills.
