Ljubljana at the bottom of the European cities ranking for cleanest air
Copenhagen – While Stockholm, Reykjavik, and Helsinki are the cleanest cities in Europe in terms of air quality, the Slovenian capital Ljubljana has found itself at the bottom of the ranking. Out of 761 cities, it ranked 709th, according to the latest updated version of the European cities air quality index prepared by the European Environment Agency (EEA).
The EEA measures air quality in European cities using data on PM 2.5 particle concentration and exposure to nitrogen dioxide and ozone over the past two years.
While the top twenty cities in the ranking for the best air quality are dominated by Finnish, Swedish, and Norwegian cities, Slovenia, with Ljubljana and its second-largest city, Maribor, ranks 709th and 589th out of a total of 761 cities on the list.
As the center of the country, Ljubljana is heavily burdened by traffic, also due to daily migrations, and motorized traffic or emissions from diesel vehicles significantly affect air quality, further worsened during the heating season by individual heating systems. (July 5)
