Question to the Department for Transport:

To ask the Secretary of State for Transport, if he will make an estimate of the level of lead emissions arising from the use of (a) leaded and (b) other fuel in the aviation sector in the UK in the last 12 months.

Figures published by the Department for Energy Security and Net Zero show Avgas, which is the only leaded fuel for aircraft, represents less than 1% of total aviation fuel supply in the UK in 2022. Avgas is mostly an issue for small piston aircrafts and it does not impact commercial aircraft using Avtur (aviation turbine fuel).

DfT will continue to monitor progress in the transition away from leaded fuels working with the Department for the Environment, Food, and Rural Affairs and the Health and Safety Executive who lead on the regulation of chemicals.
