Low Emission Zone (LEZ)

LEZ emission standards

We are following the minimum emissions standards for virtually all petrol and diesel vehicle classifications that are set out in the Low Emission Zones (Emission Standards, Exemptions and Enforcement) (Scotland) Regulations 2021.

Entry into the LEZ will be based on the Euro emission engine classification standards that are used both internationally and nationally.

The minimum criteria are

  • Euro 4 for petrol cars and vans (generally vehicles registered from 2006)
  • Euro 6 for diesel cars and vans (generally vehicles registered from September 2015)
  • Euro VI for buses, coaches and HGVs (generally vehicles registered from January 2013)
  • all zero emission vehicles, including electric vehicles (EVs), meet the LEZ minimum emission standards.

Note: these dates are only indicative - please check your vehicle with your vehicle’s manufacturer and on Transport Scotland's online vehicle checker.
