A Clean Air Zone is an area where targeted action is taken to improve air quality, in particular by discouraging the most polluting vehicles from entering the zone. No vehicle is banned in the zone, but those which do not have clean enough engines will have to pay a daily charge if they travel within the area.

The Birmingham Clean Air Zone is the area inside the A4540 Middleway Ring Road and came into force in June 2021. The journey planner shows the area covered by Birmingham’s Clean Air Zone on the map.

More details on the Birmingham Clean Air Zone can be found on the Transport for West Midlands website.
