Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what recent assessment he has made of the potential future use of alternative fuels to reduce emissions.

The Department for Transport has published outputs of the transport energy model on www.gov.uk alongside the Road to Zero Strategy (https://www.gov.uk/government/publications/reducing-emissions-from-road-transport-road-to-zero-strategy).

The transport energy model assesses the energy consumption, air quality pollutant emissions and greenhouse gas emissions of a range of road transport fuels and technologies.
