Warsaw, Poland Air Quality & Smog

Dominant pollutants, when pollution and smog are worst, a notable historical episode, and the official monitoring agencies for Warsaw, Poland — plus how to check the current reading. Warsaw reports air quality on the European Air Quality Index — our full guide explains how that scale works and how it compares to the US AQI.

Dominant pollutants

PM2.5 / PM10 and benzo(a)pyrene (winter solid-fuel heating).

Seasonal pattern: when smog is worst

Poland has some of the worst particulate and benzo(a)pyrene levels in the EU, driven by "low emission" — pollution from coal- and wood-burning home stoves — layered onto traffic and winter inversions. Warsaw's smog is sharply seasonal, peaking on cold, still winter days.

A notable air-quality episode

Persistent winter smog drove Poland's regions to adopt "anti-smog resolutions" restricting the dirtiest solid fuels, and Warsaw routinely issues smog alerts when PM levels spike in winter.

The local index and who runs it

Warsaw reports air quality using the European Air Quality Index, not the US AQI — so the same air can read as a different number than you may be used to. Poland's GIOŚ publishes station readings and a national index; the EEA aggregates Poland into the common European Air Quality Index.

• GIOŚ (Chief Inspectorate of Environmental Protection)
• European Environment Agency (EEA)
