What information was presented to the Scottish Government which conclusively demonstrated the need for the imposition of the Low Emission Zones (LEZs) in Scotland?


In order for a LEZ scheme to be made, a proposal to make the scheme must be prepared by each local authority for approval by the Scottish Ministers. This is a requirement of Section 10 of the Transport (Scotland) Act 2019.

The local authority LEZ scheme proposal must include the full details of the scheme for Scottish Ministers to review and approve, including the location and area of the proposed scheme, the date the scheme comes into effect, the types of vehicles to which the LEZ applies, the scheme’s objectives and the grace periods.

Further information on the Ministerial Approval process is outlined in Section 8 of the LEZ Guidance document, available at: Low Emission Zone Guidance (

Each of the 4 proposals to make a scheme submitted to Scottish Minister’s for approval, prior to LEZ introduction, can be found via the following links:
