Question to the Department for Transport:

To ask the Secretary of State for Transport, what comparative assessment he has made of the proportion of buses in London and the UK that are hybrid electric; and if he will make a statement.

The information is not available in this form. However, the attached table (and in the link below) shows the number of buses funded as part of the English Green Bus Fund, including hybrid buses:

Details of hybrids in the rest of the UK would be a matter for the relevant devolved administration.
