What environmental stickers are there in Germany?

There are three colours: red, yellow, and green. In practice, only the green sticker is still usable. Red and yellow are no longer accepted in any environmental zone. The colour you receive depends on how clean your car is.

For electric and plug-in hybrid vehicles, there is also an optional blue E-Plakette. This gives you additional benefits in more and more cities, such as free parking or access to zero-emission zones. Please note: the blue sticker does not replace the green environmental sticker.
