Frequently asked questions

Which is the most polluted city in the world right now?

Banjarmasin, Indonesia, at US AQI 277 (Very Unhealthy), measured by 1 monitoring station.

Which city has the cleanest air right now?

Sydney, Australia, at US AQI 6.

Why use the US AQI for a world ranking?

National scales differ. India's NAQI calls PM2.5 of 30 µg/m³ "Good" while the US scale already calls it "Moderate", so numbers from different scales cannot be compared. Converting every city's measurements with the same US EPA formula makes the ranking fair.

Are modelled estimates included?

No. Only cities with at least one monitoring station reporting are ranked. Countries need at least three such cities to appear in the country table.
