Clean Air Zone (CAZ)

A Clean Air Zone (CAZ) 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 Government has said that Birmingham needs a Clean Air Zone by January 2020 and that we need to reduce levels of NO2 in the air to a maximum average of 40μg/m3 as soon as possible. Once we reach that target, we want to continue to lower the amount of NO2 and PM in the air as far as we can.

Birmingham plans to introduce a Clean Air Zone covering all roads within the A4540 Middleway Ring Road (but not the Middleway itself) from 1 January 2020.
