Nowy Sacz in Poland has the most polluted air of any city in Europe, according to the latest report on air pollution from the European Environment Agency (EEA). The EEA's Air Quality in Europe 2020 has been released, and while the report shows some improvement to the quality of air across the continent it also reveals that more than half the cities in Europe analyzed for the report recorded "bad" or "poor" air quality during 2020.
The Air Quality in Europe report provides an annual assessment of the status and impact of air quality in Europe. Air quality in Italy and Poland is particularly bad. Both Poland and Italy have two cities each in the top five most polluted cities in Europe. The three cities with the cleanest air are Umeå, Sweden, Tampere, Finland and Funchal, Portugal. The EEA report only analyzed cities with a population over 50,000 and which have air quality records for at least 75% of the year.
You can explore the results recorded for individual cities across Europe on an interactive map showing each city's air pollution data. How Clean is the Air in my City? is an interactive visualization of the Air Quality in Europe 2020 report. Individual cities on the map are colored by the recorded annual mean concentration of PM2.5 (with green being the cleanest and dark red the most polluted). The map is accompanied by an interactive table, which ranks all the 323 cities with air quality data from the cleanest to the most polluted.
