Switzerland faces significant air pollution challenges. 100% of states exceed the WHO guideline for clean air. This is putting 8.8 million across 26 states at risk.
The average PM2.5 over 2023 was 7.3µg/m³. That's 1.5 times the WHO guideline for clean air of 5µg/m³.
This is equivalent of everybody, including children, smoking about 121 cigarettes in a year.
Every person in Switzerland is losing 0.23 years of their life to air pollution. This isn't just a statistic—it's grandparents who won't see their grandchildren graduate. Parents missing birthdays. Lives cut short. Breathing kills.
These stolen years come from diseases you know—COPD that makes every breath a struggle, lung cancer that turns healthy tissue deadly, heart attacks that strike without warning, strokes that change everything in an instant. Air pollution doesn't just kill. It damages your body from the inside, every single day.
Across Switzerland, 2.0M years of life hang in the balance. That's the collective future being taken from 8.8 million people—simply by breathing.
