I know from experience that my hon. Friend is a doughty champion for his local area and for the aviation sector. My Department is in regular contact with the Department for Transport and the Treasury on aviation decarbonisation and the important role for sustainable aviation fuel in that transition. On 25 April, DFT published a consultation on options for a revenue certainty mechanism alongside details of the SAF mandate, which together will support both decarbonation and the growth of the sector.
