Aviation: Alternative Fuels
The question
To ask the Secretary of State for Transport, what estimate she has made of the proportion of the total cost of compliance with the Sustainable Aviation Fuel Mandate represented by the compliance fees charged by sustainable aviation fuel suppliers.
Answered by Keir Mather
As part of the Sustainable Aviation Fuel (SAF) Mandate cost-benefit analysis, the total cost of compliance was estimated by looking at the additional cost of supplying SAF compared to kerosene, as well as the change to any carbon price obligation that applies.
A high-level assessment of the additional administrative costs which may be faced by fuel suppliers when complying with the SAF Mandate was included in the non-monetised costs in section 4.
