Connecticut faces significant air pollution challenges. 100% of districts exceed the WHO guideline for clean air. This is putting 3.7 million across 8 districts at risk.
The average PM2.5 over 2023 was 7.8µg/m³. That's 1.6 times the WHO guideline for clean air of 5µg/m³.
This is equivalent of everybody, including children, smoking about 129 cigarettes in a year.
If Connecticut met the WHO guideline of 5 µg/m³, the average person would live 0.28 years longer.
That's 1.0M years of life stolen from 3.7 million people. Years of watching children grow up. Years of building a career. Years of quiet mornings and celebrations.
Lives cut short. Breathing kills.
