What is a clean air zone?
Liverpool City Council are required to consider a Clean Air Zone as part of the Clean AIr Plan. This is what a Clean Air Zone is.
A Clean Air Zone (CAZ) is a targeted measure taken to improve air quality resulting from pollution from vehicles
A CAZ aims to reduce Nitrogen Dioxide (NO2) emissions which are harmful to human health
A charging CAZ imposes a charge on non-compliant vehicles when entering a distinguished boundary, dependent on vehicle type. Non-compliance is determined by a vehicle’s Euro standard.
Types of Clean Air Zone
CAZs are categorised from Class A to D, with CAZ D being the strictest form
Each CAZ type imposes restrictions on specified vehicle types and fuel types
If vehicles are older than the specified minimum Euro Standard based on their fuel type, they will be charged for entering the CAZ boundary
The minimum requirement for cars, vans and taxis will be Euro VI Diesel (manufactured after September 2015) and/or Euro IV petrol (manufactured after January 2006).
The minimum requirement for HGV and Buses/Coaches will be Euro VI (manufactured after September 2015)
