This morning I discovered on a car a green environmental badge with DEKRA stamp! Should there be … What made me stubborn, however, was the license plate, which apparently was not true. Instead of the car registration plate stood in the white field MK (for Märkischer Kreis) – can. Even after several times looking I could decipher the whole thing only as MK-KANN. However, the car registration plate was MK-SJ 2190 or similar. My question: Is the environmental badge an official document and the wrong Ke nnmarke thus forgery of documents? What consequences could it have for the car owner?
