Sustainable Aviation Fuel Bill

Julia Buckley Excerpts

Report stage
Wednesday 15th October 2025 Commons Chamber

[Edward Morello (West Dorset) (LD)]

Sustainable aviation fuel offers us a route to decarbonise one of the most carbon-intensive industries and to secure the future of our aviation sector in a way that is compatible with our net zero goals. Climate change remains the greatest challenge of our time. It is an existential threat to us, our children and our grandchildren, and every decision made in this House must be measured against the scale and the urgency of the crisis.

Aviation, while connecting people and driving our economy, is a contributor to the problem. In 2022, it was responsible for almost 30 million tonnes of CO₂, equivalent to about 7% of the UK’s total emissions. Even as emissions from other sectors decline, aviation’s share is projected to rise to 16% by 2035. That is not compatible with our net zero targets, nor with our moral obligation to keep global temperature rises below 1.5°.

Sustainable aviation fuel is not a silver bullet, but it is a step towards addressing the challenge. As someone who spent almost a decade working in renewable energy, I have seen how technology, innovation and the public trust must work hand in hand if we are to make lasting progress in addressing climate change. However, with innovation must come accountability, which is why I have tabled new clauses 4 and 5. These new clauses would strengthen this Bill and aim to make the transition to clean flight more accountable, more transparent and, yes, more ambitious. New clause 4 would support the Secretary of State to raise sustainable fuel targets in any given year and introduce a duty to consider annually whether the target should be increased. The Secretary of State would also be required to set out what steps the Government will take to make any increase possible. In short, to ensure that the Government cannot forget the targets, it would require them to revisit, review and, wherever possible, raise their ambitions for cleaner flight.

New clause 4 would strengthen the parliamentary scrutiny. It would require the Government to lay a copy of each annual report before Parliament and share it with the relevant Select Committees in both Houses, meaning proper oversight and public accountability. Progress must not just be made; it must be seen to be made if we are going to take the public with us.

New clause 5 would build on that principle of transparency and public engagement, requiring air travel providers to report annually on their sustainable aviation fuel in a way that passengers and the public can actually understand. Too often, data about emissions and fuel use is buried in complex technical reports that mean little to consumers. Under this proposal, airlines would publish both the total amount of SAF used and the proportion it represents of their overall fuel consumption.

[Julia Buckley (Shrewsbury) (Lab)]

The hon. Gentleman is giving a very detailed speech. Would he agree that we already have the annual carbon budget audit, which looks each year at exactly those emissions and was what drew to our attention the growth in this sector and why we need to focus exactly on driving down emissions from the aviation sector, which led us to the SAF mandate? Does he acknowledge that we already have a mechanism for this, which has helped us to get to where we are today with this excellent Bill?

[Edward Morello]

I thank the hon. Member for her intervention. She managed to make a detailed speech sound like a backhanded compliment. I do not disagree with her point that we have several reporting standards, and my only counter-argument would be that I do not believe there can be too much transparency. If that results in information being presented in a way that gives the public further clarity and puts greater pressure on any Government to speed up the transition, that can only be a good thing.

Those figures must be presented clearly in a format that is accessible and easy to find on websites and in public material. That matters, because whether it is demonstrating that solar and wind power lower bills, that carbon removal technology will provide jobs or that sustainable aviation fuel can cut emissions, we must be transparent to build public trust and belief in what we are doing. The powers in this Bill to fund the strike price mechanism to levy fines on fuel suppliers who fail to pay are all welcome, but they must be matched by equally strong accountability to this House and the general public. The amendments I have proposed would ensure that the Government are required to review progress every year, to explain how targets will be strengthened, and to make transparent the actual use of sustainable fuel across the aviation industry.
