Air quality indexes and pollution alerts: country by country

Of 62 countries, 37 run their own air quality index and 9 use the European one; official pollution alerts were confirmed in 32.

Updated 2026-10-27· 138 official sources

Short answer. Of the 62 countries compared, 37 publish a national air quality index of their own, such as the US AQI 1 or India's NAQI 2; 9 rely on the European Air Quality Index 3; 16 have no national index confirmed in official sources. Official pollution or smoke alerts or advisories were confirmed in 32 countries, three of them only in one region, such as Delhi-NCR 2.

How do the 62 countries compare?

Each country links to its page. "Not found in official sources" means the official sources reviewed show no such index or alert; "unconfirmed" means one may exist but no verified official source confirmed it. A regional or city source is named as such. To learn what the numbers mean for your health, see how to read an air quality index and the air section.

Countries with a national index of their own

Thirty-seven countries name an index of their own. Most share one of three designs:

  • 0-500, built like the US AQI: the United States 1, India 2, South Korea 119, Taiwan 123, Turkey 75, Colombia 90, Kuwait 132 and the United Arab Emirates 136. Malaysia 113 and Singapore 118 also run 0-500 style scales, from Good at 0-50 to Hazardous above 300.
  • 1-10 health scales: Canada's AQHI 85, Ireland's AQIH 38 and Belgium's BelAQI 6.
  • Named classes: France's six ATMO classes 23, Germany's five 30, Norway's four 51, Spain's six aligned with the European index 69 and Slovakia's three 64.

The same word can mean different air. Norway's top class starts above 150 µg/m³ of PM2.5 51, while Georgia's top PM2.5 class starts at 50 µg/m³ 28. Compare the band, not the label; the air quality index guide explains when to act.

In six of these countries the scale itself is unconfirmed or only partly confirmed: Brazil, Estonia, Iceland, Indonesia, Israel and the Philippines. Brazil's categories, for example, could not be checked against the official text 81.

Countries using the European Air Quality Index

Nine European countries rely on the European Environment Agency's six-class index, Good to Extremely poor 3: Bulgaria 8, Croatia 10, Cyprus, Denmark, Greece, Latvia, Malta, Slovenia and Italy, where regional agencies also publish their own indices 40. In Denmark the Aarhus University centre publishes concentrations and a smog alarm but no Danish index was found 15.

Countries without a confirmed national index

Sixteen countries have no national index confirmed. Some have none by design: New Zealand sets concentration standards instead 114 and Japan sets per-pollutant thresholds such as the PM2.5 caution level 109. Chile declares PM2.5 episodes in zones with decontamination plans 89. Australia has none nationally; New South Wales uses its own categories 103. Austria's networks are run by each Land 4. For Argentina, Moldova and Ukraine no regulatory index was found; Ukraine's ministry map borrows the US EPA PM2.5 NowCast 76. In Switzerland, Chile, Costa Rica, Kazakhstan, Lithuania, Luxembourg, Peru, South Africa and the United Kingdom an index may exist but was not confirmed in a verified source on 27 Oct 2026.

Countries without an official alert found

Nine countries show no official pollution or smoke alert in the sources reviewed: Argentina, Brazil, Bulgaria, Georgia, Latvia, Moldova, New Zealand, the Philippines and Ukraine. In several, the national weather service warns of storms or humidity but not of polluted air: Argentina 79, Brazil 82 and Latvia 41.

In twenty-one more an alert may exist but no verified source confirmed it: Austria, Costa Rica, Croatia, Cyprus, Estonia, Greece, Hungary, Indonesia, Israel, Italy, Kuwait, Lithuania, Malta, Mexico, Peru, Qatar, Serbia, South Africa, Spain, Switzerland and Turkey.

Where no alert reaches you, the index is your warning. Learn the signs of an ozone day and wildfire smoke, and prepare a clean-air room.

Frequently asked questions

Can I get air pollution alerts by text or e-mail?

In some countries, yes. The United States offers EnviroFlash by e-mail or text 101, the United Kingdom's Check air quality service sends e-mail or SMS alerts 77, and Northern Ireland runs Air Aware by SMS 78. Portugal's notices appear in the QualAr app 58, and Luxembourg's in the Meng Loft app 45.

Are wildfire smoke warnings part of air quality alerts?

Sometimes. Canada's special air quality statements cover smoke 86, the US National Weather Service issues Dense Smoke Advisories 99, Germany sends smoke warnings through NINA 32 and Sweden through its public warnings (VMA) 72. Victoria's EPA covers smoke in its notices 105. See masks for smoke.

Is a "moderate" day the same everywhere?

No. Each index sets its own limits. Ireland's "Poor" band runs from 7 to 9 out of 10 38, while India's "Poor" covers 201-300 on a 0-500 scale 2. Read the advice attached to your own country's bands; see polluted air for sensitive people.

Who issues pollution alerts: the country or the city?

It varies. Japan sets the PM2.5 guideline nationally but prefectures issue the alerts 109. Norway's municipalities issue warnings 52, and Finland's episodes are announced by cities 21. In India the GRAP stages apply to Delhi-NCR 2, and in Colombia to Bogotá and the Valle de Aburrá 91.

Making air alerts part of your plan

Note your country's index, the band at which you change plans, and where you check it. When an episode is declared, follow what to do during a pollution episode. If your country sends no alerts, set a daily habit of checking the live page listed above. The Phaenyx plan lets you record these steps with the rest of your household's preparations.
