Overview

Air Pollution in Sichuan

Sichuan faces significant air pollution challenges. 100% of districts exceed the WHO guideline for clean air. This is putting 85.5 million across 22 districts at risk.

The average PM2.5 over 2023 was 31.1Āµg/mĀ³. That's 6.2 times the WHO guideline for clean air of 5Āµg/mĀ³.

This is equivalent of everybody, including children, smoking about 516 cigarettes in a year.

Annual PM2.5 levels from 2014 to 2023. The WHO guideline for safe air is 5 Āµg/mĀ³.

Health Impact

Life Expectancy Impact

If Sichuan met the WHO guideline of 5 Āµg/mĀ³, the average person would live 2.55 years longer.

That's 218.0M years of life stolen from 85.5 million people. Years of watching children grow up. Years of building a career. Years of quiet mornings and celebrations.

Lives cut short. Breathing kills.
