Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the Answer of 23 November 2021 to Question 76827 on Aviation: Fuels, what progress his Department has made on assessing the potential merits of (a) regulatory mechanisms and (b) other methods that could be used to encourage the aviation sector to use UL91 fuel; and what discussions he has had on that work with the aviation sector.

The Secretary of State has asked his officials to speed up work on finding safe alternative unleaded fuel such as UL91. Since then, the Department has engaged with sector stakeholders, international aviation regulators such as the FAA, and aviation fuel manufacturers, to identify effective measures. A survey to understand the sentiment of airfields and aircraft operator clubs has just closed and will be used to inform further policy interventions. Options that could be considered include information campaigns, improving the data and evidence, and measures to affect the relative price or access to different fuels. As this is still at policy development stage, engagement has been by officials, and the Secretary of State has not had significant discussions with the aviation sector on this.
