Question to the Department for Transport:

To ask the Secretary of State for Transport, if he will make it his policy to require aircraft to use unleaded fuels.

The Government is supporting the development of new aviation fuels through a range of measures including developing a Sustainable Aviation Fuels mandate and the Advanced Fuels Fund.

There are some specific issues for replacing avgas, a fuel used in piston aircraft which represents less than 1% of total UK aviation fuel use.

An unleaded alternative, Unleaded 91, is now commercially available and may be used by much of the General Aviation sector. In addition, battery-electric aircraft have been certified for use in flight training. The Government encourages General Aviation operators to use unleaded alternatives to avgas when suitable for their aircraft.

The Government has no plans to require the testing of children.

DfT will continue to monitor progress in the transition away from leaded fuels working with DEFRA and the Health and Safety Executive who lead on the regulation of chemicals.
