The environmental zone is an area where only vehicles which comply with emission standards can drive. Vehicles with especially high emissions have to stay out of it.

The environmental zone covers the centre of Berlin inside the S-Bahn ring. This has an area of approximately 88 km². The area is particularly closely built-up. Around one million of the 3.4 million inhabitants of Berlin live here. The environmental zone is indicated by traffic signs at the bridges and underpasses of the S-Bahn railway. At the head of the page appears a graphic illustrating stage 1 of the environmental zone in which vehicles with red, yellow and green stickers are allowed to drive. The southern part of the city highway, which lies inside the S-Bahn ring, will not form part of the environmental zone and will remain freely accessible given that the motorway ring serves as a bypass for the zone.
