Air Pollution in Northern

Northern faces significant air pollution challenges. 100% of districts exceed the WHO guideline for clean air. This is putting 3.1 million across 5 districts at risk.

The average PM2.5 over 2023 was 9.8µg/m³. That's 2.0 times the WHO guideline for clean air of 5µg/m³.

This is equivalent of everybody, including children, smoking about 163 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 Northern met the WHO guideline of 5 µg/m³, the average person would live 0.48 years longer.

That's 1.5M years of life stolen from 3.1 million people. Years of watching children grow up. Years of building a career. Years of quiet mornings and celebrations.

Lives cut short. Breathing kills.
