Question to the Department for Transport:

To ask the Secretary of State for Transport, if he will introduce a sub-mandate on power-to-liquid fuels to help decarbonise aviation.

Sustainable aviation fuel (SAF) will have a key role in driving down carbon emissions in the UK aviation sector and the Government is fully committed to accelerating its development. The Government recognises the long-term potential of power-to-liquid (PtL) fuels specifically, due to the feedstock availability and high greenhouse gas (GHG) emissions reductions they can achieve. However, PtL fuel costs are significantly higher than the cost of SAF produced through any other pathway and the production of these fuels is not expected to be widespread until the late 2030s.

Last year we consulted on proposals to introduce a SAF mandate in the UK, including mechanisms to accelerate the technological and commercial development of PtL fuels specifically.. We are currently reviewing evidence provided in response to the consultation and wider resources to determine which mechanism may be most effective in reducing the cost of and stimulating investment in PtL production. We will provide further clarity in the upcoming government response to the SAF mandate consultation.
