The European Environmental Agency (EEA) published the European city air viewer.

This allows people in the EU to check how the air quality was in their cities over the past two years and to compare it with air quality in other cities across Europe.

Cities are ranked from the cleanest city to the most polluted, on the basis of average levels of fine particulate matter, or PM2.5, over the past two calendar years.

Fine particulate matter is the air pollutant with the highest impact on health in terms of premature death and disease. This tool is focused on long term air quality, with long term exposure to air pollution causing serious health effects.

The database and the visualization can be accessed on this link.

According to the ‘City air viewer’ 6 out of the 10 most polluted cities are in the Central European region.

  • 5 in Poland (including Kraków)
  • 1 in Croatia (Slavonski Brod)
