Overview

Air Pollution in Nuevo León

Nuevo León faces significant air pollution challenges. 100% of districts exceed the WHO guideline for clean air. This is putting 6.0 million across 51 districts at risk.

The average PM2.5 over 2023 was 18.7µg/m³. That's 3.7 times the WHO guideline for clean air of 5µg/m³.

This is equivalent of everybody, including children, smoking about 310 cigarettes in a year.

Annual PM2.5 levels from 2014 to 2023. The WHO guideline for safe air is 5 µg/m³.

Health Impact

Life Expectancy Impact

If Nuevo León met the WHO guideline of 5 µg/m³, the average person would live 1.34 years longer.

That's 8.0M years of life stolen from 6.0 million people. Years of watching children grow up. Years of building a career. Years of quiet mornings and celebrations.

Lives cut short. Breathing kills.
