Air quality: identifying taxi and private hire vehicles in charging Clean Air Zones

We want to know what you think about our plans to identify taxis and private hire vehicles (PHVs) entering or moving within a Clean Air Zone (CAZ). We’re proposing to create a centralised database which identifies all taxis and PHVs operating in England and Wales. This will help local authorities enforce charging Clean Air Zones even if the taxi or PHV has been licensed in a different area.

It will also help identify exempted vehicles which meet the required standard for their vehicle.

CAZ defines an area where targeted action needs to be taken to reduce roadside nitrogen dioxide concentrations. These have persistently breached statutory levels and action is required in the shortest possible time.
