Pwani faces significant air pollution challenges. 100% of districts exceed the WHO guideline for clean air. This is putting 2.1 million across 7 districts at risk.
The average PM2.5 over 2023 was 9.9µg/m³. That's 2.0 times the WHO guideline for clean air of 5µg/m³.
This is equivalent of everybody, including children, smoking about 164 cigarettes in a year.
If Pwani met the WHO guideline of 5 µg/m³, the average person would live 0.5 years longer.
That's 1.1M years of life stolen from 2.1 million people. Years of watching children grow up. Years of building a career. Years of quiet mornings and celebrations.
