By 2020, the air in Germany has become significantly cleaner. According to the Minister of the Environment and Nuclear Safety of the Federal Republic of Germany Svenie Schulze, a significant decrease in the content of harmful substances in the air was recorded in 2020, compared to the previous year. Reported by Deutsche Welle.
At the same time, the minister noted that the decrease in the concentration of nitrogen dioxide and fine dust is only partially explained by the restrictions introduced against the backdrop of the coronavirus pandemic. The positive trend in this area has been continuing for many years.
In total, last year, of all German cities, only Hamburg and Munich exceeded the maximum permissible level of nitrogen dioxide in the air. The Federal Office for the Environment said the improvement was largely due to modern diesel vehicles, the introduction of more speed-limited zones in cities, and improvements in-vehicle software.
According to the study, only about three to four percent of the 400 measuring stations exceeded the average annual nitrogen dioxide limit of 40 micrograms per cubic meter of air.
Also, a 20-50 percent decrease in road traffic during the lockdown period in March-April 2020 made it possible to reduce the content of nitrogen dioxide in the atmosphere by 25 percent. According to the content of harmful small particles and dust in the air of German cities, 2020 became the cleanest year since the beginning of recording these indicators in the 1990s.
