A German 'Blaue Plakette', or 'Blue Sticker', for diesel Euro 6 vehicles in the German Low Emission Zones was confirmed by the national authorities in summer 2016.
However, in October 2016 the Transport Ministers of the German regions (Länder) decided to undertake more investigation before bringing the Blue Sticker into operation.
Low Emission Zones are referred to as Umweltzone in German.
A number of cities have expressed interest in implementing a Euro 6 Low Emission Zone, but these wait until there is agreement on the Blau Plakette nationally.
www.urbanaccessregulations.eu will keep you informed as soon as any schemes are confirmed !
