A Clean Air Zone (CAZ) is an area in the United Kingdom where targeted action is taken to improve air quality.{{cite web|url=https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/612592/clean-air-zone-framework.pdf|title=Clean Air Zone Framework|work=DEFRA and DfT|date=May 2017}} A CAZ can be non-charging or charging.{{citation needed|date=January 2022}}
Whether a vehicle is charged when entering or moving through a CAZ depends on the type of vehicle and the Euro standard of the vehicle. The amount charged is up to the local authority responsible for the CAZ. Ultra-low-emission vehicles are not charged when entering or moving through a Clean Air Zone.
