The UK city of Manchester is to impose a Clean Air Zone (CAZ) from 30 May, 2022 throughout the Greater Manchester area.

The Zone will operate 24 hours a day, seven days a week, all year round. Signage will be clear, so that vehicle drivers who do not wish to enter the Zone can take an alternative route. Daily charges will apply for each day an affected vehicle which doesn’t meet emission standards (Euro VI) is used within the Zone. One charge would be imposed per vehicle, per ‘charging day’ (midnight to midnight), however much a vehicle drives within the Zone in that 24-hour period.

Owners or registered keepers of non-compliant vehicles used within the Zone will be required to pay the relevant charge via a central government payment portal. The government plans that a user can pay seven days in advance (including the journey date) or seven days retrospectively (including the journey date). Payment of daily charges will be enforced by a network of Automatic Number Plate Recognition (ANPR) cameras.
