Supporting the Ultra Low Emission Bus Scheme

Project Brief

In 2018, DfT and the Office for Low Emission Vehicles announced a £50million package capital grant funding to support the purchase of Ultra Low Emission Buses and supporting infrastructure in England and Wales.

The grant money is aimed at accelerating the deployment of Ultra Low Emission Buses in fleets, to further improve air quality in towns and cities and reduce well-to-wheel greenhouse gas emissions from bus fleet operations. 

The Ultra Low Emission Bus Scheme draws heavily on the work carried out by LowCVP's Bus working Group on the UK Bus Cycle test and grant funding mechanism, including testing Euro VI diesel buses to establish an average greenhouse gas performance of conventional market vehicles.

An Ultra Low Emission Bus is defined as having a 30% greenhouse gas saving on a well-to-wheel basis compared to a Euro VI diesel bus of equivalent passenger capacity.

For more information on the ULEB accreditation scheme, the UK Bus Cycle test procedure and grant funding, please visit the Low Emission Bus Hub
