Sustainable Aviation Fuel Bill 2024-26


Make provision about sustainable aviation fuel.

Government Bill

(Department for Transport)
What is this Bill?

The Sustainable Aviation Fuel Bill is a Government Bill tabled by a Minister of the Crown.

Is this Bill currently before Parliament?

Yes. This Bill was introduced on 14 May 2025 and is currently before Parliament.

Whose idea is this Bill?

Government Bills implement the legislative agenda of the Government. This agenda, and the Bills that will implement it, are outlined in the Queen's Speech at the Session's State Opening of Parliament.

What type of Bill is this?

Government Bills are technically Presentation Bills, but the Government can use its legislative time to ensure the schedule of debates to scrutinise the Bill.

So is this going to become a law?

Though the Bill can be amended from its original form, the Bill will almost certainly be enacted in law before the end of the Session, or will be carried over to the subsequent Session.

How can I find out exactly what this Bill does?

The most straightforward information is contained in the initial Explanatory Notes for the Bill.
