New European city air quality viewer
The European Environment Agency (EEA) has launched a “European city air quality viewer”, where you can check how the air quality has been over the past two years in the city where you live and compare it with other cities across Europe. In the viewer, more than 300 cities are ranked from the cleanest to the most polluted, on the basis of average levels of fine particulate matter (PM2.5) over the past two calendar years.
