Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment he has made of the effectiveness of the Zero Emission Bus Regional Areas scheme.

The department has an ongoing monitoring and evaluation project in place for the Zero Emission Bus Regional Aras (ZEBRA) scheme. This will assess the extent to which the ZEBRA scheme meets its objectives and help to improve the evidence base on the performance of zero emission buses.

On 7 June 2023 the department published an interim evaluation report on the ZEBRA scheme. The report includes findings from a process evaluation of the pre-implementation phase of the ZEBRA scheme. The report can be viewed on the department’s website: https://www.gov.uk/government/publications/zero-emission-bus-regional-areas-scheme-interim-evaluation
