Exceeding the Limit Values
Especially diesel vehicles without a suitable exhaust gas purification system bear the responsibility for air pollution. As it has been known for several years, the nitrogen oxide pollution of German town centres does not correspond to legal requirements. The problem with nitrogen oxide (NO2) in Germany is preliminarily attributed to the traffic in town centres.
According to the Federal Environmental Agency (Umweltbundesamt, 01-2018), nitrogen dioxide values exceeded the allowed annual average limit value of 40 μg/m3 in 66 German cities in 2017.

The Blue Badge for Diesel Restriction Zones
In Germany, the Blue Badge might be introduced in 2020. It is required to access diesel restriction zones.
In 2020, cities and communities will introduce driving restrictions for various EURO classes of diesel vehicles. Therefore, the Blue Badge becomes a need in order to distinguish older diesel vehicles and EURO classes as well as petrol vehicles without particle filter from vehicles with a lower emission of pollutants.
