Nitric oxide data for 2019: air in German cities is getting better

The air in numerous German cities has improved significantly in 2019 – at least as far as nitrogen oxide pollution is concerned. According to a media report, this comes from figures from the Federal Environment Agency.

According to a newspaper report, the number of German cities that exceed the nitrogen oxide limit has more than halved last year. In 2019, 25 cities would have exceeded the limit of 40 micrograms of nitrogen oxide (NO2) per cubic meter of air per year on average, the newspapers of the Funke Media Group cite from an evaluation of the measurement data from more than 500 measurement stations of the federal states and the Federal Environment Agency (UBA).

Freiburg makes the biggest leap

In 2018, 57 cities were still above the NO2 target. According to the newspaper report, the largest decline among the cities that met the target last year was Freiburg im Breisgau. In 2018, 50 micrograms of NO2 per cubic meter of air were measured there on an annual average, and in 2019 the value had dropped to 36 micrograms.

The Hessian Alsfeld, on the other hand, is a new addition to the list of cities that do not meet the limit values. There was no measuring station there in 2018, last year 42 micrograms of NO2 per cubic meter of air were measured there. Munich has the highest nitrogen oxide pollution, it said.

Street in Munich replaces “Neckartor” in Stuttgart

There, the average annual value of 62 micrograms of NO2 per cubic meter of air was measured at a measuring station on Landshuter Allee. At the Stuttgart measuring station “Am Neckartor”, where the highest value in Germany was still determined in 2018 with 71 micrograms NO2, the exposure could be reduced to 53 micrograms.

UBA President Dirk Messner was confident that the overall nitrogen oxide load would decrease again this year. In an interview with the Spark newspaper, he campaigned for the correct conclusions to be drawn from the Corona crisis. She had shown that “less traffic leads to better air and less noise, which improves the quality of life in our cities”. This knowledge should be used as an occasion for a long-term turnaround in traffic, Messner demanded. The main source of nitrogen oxide in cities is diesel cars.
