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.
Portsmouth will be introducing a Class B CAZ. Non-compliant heavy goods vehicles, buses and coaches that are Euro 5 or older if diesel, or Euro 3 or older if petrol, will be charged £50 a day to drive in the zone. Non-compliant taxis and private hire vehicles that also don’t meet those standards will be charged £10 per day to drive in the zone. Vans, minibuses, motorcycles and private cars will not be charged.
