Air Pollution in Maryland

Maryland faces significant air pollution challenges. 100% of districts exceed the WHO guideline for clean air. This is putting 199 thousand across 2 districts at risk.

The average PM2.5 over 2023 was 8.9µg/m³. That's 1.8 times the WHO guideline for clean air of 5µg/m³.

This is equivalent of everybody, including children, smoking about 148 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 Maryland met the WHO guideline of 5 µg/m³, the average person would live 0.4 years longer.

That's 80K years of life stolen from 199 thousand people. Years of watching children grow up. Years of building a career. Years of quiet mornings and celebrations.

Lives cut short. Breathing kills.
