The Birmingham Clean Air Zone (CAZ)

  • Planned introduction - January 2020


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 the levels of NO2 in the air need to reduce to a maximum average of 40μg/m3 as soon as possible. Once that target is reached, the amount of NO2 and PM in the air we be further reduced as far as possible.

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.

The charges will be applied daily. A non-compliant vehicle driving in the CAZ will pay once for the day, then may drive in the CAZ area without limit on that day.

You will not have to pay a daily charge to drive in the CAZ if your vehicle is:

  • A diesel of Euro 6 (VI) standard of better (most new registrations after 1 September 2015)

  • A petrol of Euro 4 standard or better (most new registrations after 1 January 2006)

  • Zero emission, ie electric or hydrogen

  • Low emission, including CNG (compressed natural gas) and hybrids that either meet or go beyond Euro 6 diesel and Euro 4 petrol standards

  • CVRAS (Compliant Vehicle Registered Accreditation Scheme) retrofit solution, including LPG retrofits*

  • Any motorcycle or moped

* LPG retrofits that are not accredited by CVRAS are not automatically compliant. Compliance would be based on the petrol or diesel part of the engine.

Contact us to see how we can help. Our retrofit SCR (Euro 6) conversions are available for an increasingly large number of vehicles.
