Air quality in Germany improved last year – but the Corona pandemic had little impact. Hamburg and Munich still exceed the permissible limits.
Pollution levels in German cities fell last year – but the Corona crisis had little effect on air quality. According to the Federal Environment Agency (UBA), in 2020 the limit value for nitrogen dioxide (NO2) was probably only exceeded at around three to four percent of the measuring stations close to traffic. The year before, the figure was 21 per cent.
While in 2019, 25 cities were still affected by exceeding the NO2 limit value of 40 micrograms per cubic metre of air on an annual average, in 2020 it would be “significantly less than ten”, the UBA explained.
