In Prague, the proportion of all green natural areas, as well as the share of areas covered by tree canopy, is just below the average of the cities in the sample (38% and 27%).

Monitoring PM10 concentrations is one way of measuring air quality. Their average concentration has been declining across the selected cities, except in Copenhagen, since 2017. At the same time, the differences between the cities are steadily decreasing. Prague maintains an average position.

Another way of measuring air quality is to monitor nitrogen dioxide (NO₂) concentration. Its average concentration has fallen across all the selected cities since 2017. Prague performs similarly in NO2 concentration as it does in dust particle concentration, thus achieving average air quality compared to the other selected cities.
