Potential Clean Air Zone

Closed 31 Mar 2022

Opened 26 Mar 2021


In 2020, in conjunction with the Environmental Consultants AECOM, the Council began the development of a detailed Clean Air Plan Project. An Outline Business Case (OBC) is currently being developed for the Clean Air Plan, to see if different ideas to improve air quality, including a Sefton based charging Clean Air Zone, will work in Sefton. The detailed Clean Air Plan Outline Business Case work is ongoing and is likely to be complete by summer of 2022.

The Outline Business Case aims to see if there is a preferred option for a potential Clean Air Zone as part of a wider Clean Air Plan for the Borough. We will use this dedicated Clean Air Plan consultation page to keep you up to date with the progress and outcomes of the Outline Business Case and whether it progresses to a Full Business Case.

What is a Clean Air Zone?

A Clean Air Zone is an area in which a local authority has brought in targeted actions to improve air quality by reducing pollution and encouraging people to drive less polluting vehicles, including electric and low emission vehicles. A CAZ can be charging or non-charging to vehicles and can be applied to specific types of vehicles only i.e. depending on vehicle type and its specific Euro emissions classification.

A Clean Air Zone is designed to improve air quality by encouraging upgrades to cleaner vehicles. It is not the same as a Congestion Charge Zone, where all or most vehicles are charged to drive.

The government published its Clean Air Strategy in 2019 – this sets out the comprehensive actions required across all parts of the government and society to improve air quality – including Clean Air Zones.  A copy of the strategy is available here: Clean Air Strategy 2019
