Tehran faces significant air pollution challenges. 100% of districts exceed the WHO guideline for clean air. This is putting 13.3 million across 9 districts at risk.
The average PM2.5 over 2023 was 21.8Āµg/mĀ³. That's 4.4 times the WHO guideline for clean air of 5Āµg/mĀ³.
This is equivalent of everybody, including children, smoking about 362 cigarettes in a year.
If Tehran met the WHO guideline of 5 Āµg/mĀ³, the average person would live 1.64 years longer.
That's 21.8M years of life stolen from 13.3 million people. Years of watching children grow up. Years of building a career. Years of quiet mornings and celebrations.
