Zero Emission Bus Certificates

This page displays the Zero Emission Bus (ZEB) certificates for models that qualify for capital grant funding in the UK, such as the ZEBRA or ScotZEB schemes, as well as the Zero Emission Bus BSOG uplift in England.

ZEB accreditation is required to ensure public money supports proven technologies that will perform in-service. Certificates enable local authorities and bus operators to understand the expected performance ahead of time and compare different suppliers and technologies.

To achieve accreditation and certification, vehicles must:

  • have no combustion engines on-board (including diesel heaters)
  • produce no regulated emissions from the tailpipe(s)
  • achieve a 50% well-to-wheel greenhouse gas saving compared to a conventional Euro VI diesel over the UK Bus Cycle.

Once a manufacturer or vehicle supplier has demonstrated a bus model achieves the ZEB standard, Zemo Partnership and DfT review the certificate and publish it below along with highlights of the vehicle's specifications and performance.

ZEB manufacturers and suppliers can then provide operators/local authorities with the ZEB test certificates and vehicle summary sheets which can then be used to claim capital grant funding and BSOG ZEB uplift in England.

Annual Updates

Zemo updates ZEB certificates each year on the 1st February with new emission factors for grid electricity and hydrogen. This is sourced from the ‘Government conversion factors for company reporting of greenhouse gas emissions’.

Certificates were last updated on 10 May 2022.
