Blue Environmental Badge in Germany
The blue badge aimed to reduce the concentration of nitrogen oxides (NOx) and improve the air quality in cities by restricting entry to older diesel cars.
The introduction of the blue environmental badge was rejected by the German federal government, meaning it never came into effect.
Who Would Have Received the Blue Badge?
Petrol vehicles that met the green badge requirements would have been entitled to the blue badge. The problem would have arisen with diesel cars, for which stricter rules would have applied. It was assumed that only diesel cars with a minimum level of air pollution that met the Euro 6 emissions standard would have received the sticker. It would therefore have included newer diesel cars with a production date from September 2015. At the end, the blue environmental badge was never introduced.
Blue Low Emission Zones
Although a nationwide “blue badge” system was never established, local “blue” low emission zones were introduced only in Munich, Stuttgart and Darmstadt. In Berlin and Hamburg, similar local measures were later abolished.
It is intended to concern cities and municipalities that regularly exceed nitrogen oxide limits. These low emission zones have either permanent or temporary validity, for example, in cases of extremely high concentrations of pollutants or during selected time periods.
Such strict conditions would complicate transport for many German citizens who own diesel vehicles; the expansion never took place nationwide.
