PM2.5 air pollution

Tier A· Official

Population-weighted average exposure to fine particulate matter (PM2.5) — the air pollutant most linked to health harm.

100 = cleanest air (lowest PM2.5), 0 = most polluted

How this score is built

Mean annual population-weighted exposure to fine particulate matter (PM2.5) — World Bank indicator EN.ATM.PM25.MC.M3 (from satellite + ground data, van Donkelaar et al. / WHO). Direction is higher_worse. The distribution is skewed (a few countries far exceed the WHO 5 µg/m³ guideline), so we normalize with percentile rank and invert: 100 = cleanest air. The raw µg/m³ is shown. Most recent available year per country.
