Castilla y León faces significant air pollution challenges. 89% of districts exceed the WHO guideline for clean air. This is putting 2.4 million across 9 districts at risk.
The average PM2.5 over 2023 was 5.6µg/m³. That's 1.1 times the WHO guideline for clean air of 5µg/m³.
This is equivalent of everybody, including children, smoking about 93 cigarettes in a year.
If Castilla y León met the WHO guideline of 5 µg/m³, the average person would live 0.06 years longer.
That's 143K years of life stolen from 2.4 million people. Years of watching children grow up. Years of building a career. Years of quiet mornings and celebrations.
