Sustainable Aviation Fuel Bill Remaining Stages: Amendment 8

What happened: The House of Commons voted on Amendment 8 to the Sustainable Aviation Fuel Bill at its remaining stages on 15 October 2025. The amendment, which sought to strengthen environmental standards or accelerate the implementation timeline for sustainable aviation fuel requirements, was defeated by 319 votes to 151.

Why it matters: The Sustainable Aviation Fuel Bill sets the framework for how aviation fuel sourced from non-fossil alternatives will be mandated and regulated in the UK. Amendment 8 would have imposed more demanding environmental conditions or a faster timetable on the sector. Its defeat means the government's approach, which prioritises a more gradual transition and greater flexibility for industry, will proceed. The outcome affects airlines, fuel suppliers, and the broader aviation sector, as well as the UK's ability to meet its climate commitments from one of its harder-to-decarbonise industries.

The politics: The vote divided almost entirely along government-versus-opposition lines. Labour and Labour and Co-operative members voted unanimously against the amendment, while Conservatives and Liberal Democrats voted unanimously in favour. The Greens, notably, voted No alongside the government, suggesting their opposition to the overall bill or a specific concern with this amendment's framing. Small numbers from the DUP, Reform UK, and the Ulster Unionist Party voted Aye. The result, with a government majority of 168, reflects the comfortable parliamentary arithmetic Labour has enjoyed since the 2024 general election, and mirrors similar defeats for opposition environmental amendments seen in related votes the same day and in subsequent weeks.
