Overview

Air Pollution in Saitama

Saitama faces significant air pollution challenges. 100% of districts exceed the WHO guideline for clean air. This is putting 7.3 million across 70 districts at risk.

The average PM2.5 over 2023 was 11.3µg/m³. That's 2.3 times the WHO guideline for clean air of 5µg/m³.

This is equivalent of everybody, including children, smoking about 187 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.

Health Impact

Life Expectancy Impact

If Saitama met the WHO guideline of 5 µg/m³, the average person would live 0.63 years longer.

That's 4.6M years of life stolen from 7.3 million people. Years of watching children grow up. Years of building a career. Years of quiet mornings and celebrations.

Lives cut short. Breathing kills.
