Air Pollution in Kisii

Kisii faces significant air pollution challenges. 100% of districts exceed the WHO guideline for clean air. This is putting 1.2 million across 9 districts at risk.

The average PM2.5 over 2023 was 22.6µg/m³. That's 4.5 times the WHO guideline for clean air of 5µg/m³.

This is equivalent of everybody, including children, smoking about 375 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 Kisii met the WHO guideline of 5 µg/m³, the average person would live 1.73 years longer.

That's 2.1M years of life stolen from 1.2 million people. Years of watching children grow up. Years of building a career. Years of quiet mornings and celebrations.

Lives cut short. Breathing kills.
