San Luis Potosí faces significant air pollution challenges. 100% of districts exceed the WHO guideline for clean air. This is putting 2.9 million across 58 districts at risk.
The average PM2.5 over 2023 was 16.7µg/m³. That's 3.3 times the WHO guideline for clean air of 5µg/m³.
This is equivalent of everybody, including children, smoking about 277 cigarettes in a year.
If San Luis Potosí met the WHO guideline of 5 µg/m³, the average person would live 1.13 years longer.
That's 3.3M years of life stolen from 2.9 million people. Years of watching children grow up. Years of building a career. Years of quiet mornings and celebrations.
