Sustainable Aviation Fuel Bill

Graham Leadbitter Excerpts

2nd reading
Wednesday 11th June 2025 Commons Chamber

[Graham Leadbitter (Moray West, Nairn and Strathspey) (SNP)]

The SNP welcomes the Bill, which will support the expanding use of sustainable aviation fuel. We view that as an important action among the range of actions that are needed to meet our legal and—most importantly —moral obligations to reduce carbon and support global efforts to tackle climate change.

My constituency has already played an important role in the use of SAF, with RAF Lossiemouth being the first Air Force base to use a SAF fuel blend for routine operations, for both the Poseidon submarine hunters and the Typhoon squadrons operating with a SAF mix. The RAF has also conducted demonstrator flights with 100% SAF-fuelled aircraft, and refuelled jets in the air with SAF. Indeed, Group Captain Sarah Brewin, the station commander at RAF Lossiemouth, has stated:

“The use of sustainable aviation fuel represents a significant milestone in the RAF’s journey towards helping mitigate against climate change. By integrating sustainable practices into our operations, we are not only enhancing our ability to protect the nation and deliver excellence on operations, but also contributing to a more sustainable future for generations to come.”

I welcome the fact that the RAF has some ambitious targets to reduce its aviation carbon emissions.

Inverness airport, publicly owned by Highlands and Islands Airports Ltd and responsible to the Scottish Government, has offered SAF to operators since 2023—a vital piece of work towards the Scottish Government’s deliberately ambitious goal of creating the world’s first net zero aviation region by 2040.

Offshore supply flights are one of the most promising parts of our aviation sector for SAF potential. With Scotland having the lion’s share of these flights from Aberdeen airport, it is vital that we see investment in SAF production in Scotland. Aberdeen airport, operated by AGS Airports, has supplied SAF since 2022, helping offshore industries to reduce their emissions. In 2021, one of the first fully-SAF helicopter flights in the UK took off from Aberdeen airport. BP is working with Bristow Helicopters to ensure that flights to BP platforms have used a SAF blend for more than two and a half years.

Scotland has an immense SAF production potential. The Bill alone is insufficient to see us reach that potential, but it is an important part of that. Scotland’s SAF progress has been held back by the inaction of successive UK Governments on funding the Scottish carbon capture, usage and storage cluster. The CCUS cluster is, in turn, integral to the investment in SAF production at Grangemouth.

Industry body Sustainable Aviation found that a UK SAF industry could deliver £2.9 billion annually to the UK economy, and create more than 20,000 jobs. It is vital that, with long-overdue funding finally confirmed today—something that the SNP has campaigned on for over a decade—the full detail is rapidly made clear and that pace is further injected into the process if that overdue cash is to be converted to construction and processing.

My SNP colleague and Transport Secretary in the Scottish Government has put in place an expert working group on sustainable aviation fuel to exploit the potential for the Scottish economy.

I have covered our broad welcome for the Bill, but there is one area that the Government must address, which is ensuring that feedstocks are coming from sustainable sources. We welcome the Secretary of State’s comments on further design work in the process and we will see that come through in the passage of the Bill. However, the Government must set out how they plan to manage the sourcing of sustainable aviation fuel feedstocks, so that the waste hierarchy is adhered to, and that existing businesses are not damaged by the introduction of the revenue certainty mechanism.

The most obvious illustration of this is the potential use of high-quality wood as one potential feedstock for SAF production. Some Members, but I suspect not all, will be aware that current demand for wood will outstrip supply by 2035. It will be obvious to everyone that it takes more than 10 years to grow a forest, so there is a real and well-articulated concern from organisations such as the Wood Panel Industry Federation and the many sawmill operators throughout the UK.

The UK wood panel industry currently supplies 65% of the UK’s demand for wood panel products, utilising 25% of the annual roundwood harvest basket and 25% of the annual waste wood basket. Fully 10% of the UK economy utilises wood panel products and, again, it will not be lost on the Government that, in order to achieve a 1.5 million new homes target—something the SNP welcomes, given our own substantial success in social and affordable housing build in Scotland—protecting and growing wood supply will be absolutely vital.

The eligibility criteria for the SAF mandate stipulates that feedstock materials must be waste that cannot be prevented, reused or recycled in accordance with the waste hierarchy. While the mandate acknowledges the waste hierarchy, which in principle would prioritise the use of waste wood for recycling before energy recovery, it is not clear how it will be monitored and enforced, leaving supplies of waste wood vulnerable to being used in SAF, against the eligibility criteria. There is a risk that the introduction of a revenue certainty mechanism will incentivise producers wishing to use this essential raw material for SAF production.

There will be time during the passage of the Bill for Ministers to mitigate this risk and address this issue across the Departments involved, of which there are several. I particularly hope that the Deputy Prime Minister’s responsibility for housing will help to focus ministerial and wider departmental minds on ensuring that the final iteration of the Bill supports sustainable SAF feedstocks. There are many good ways to manufacture SAF, and there are some bad ones. Let us get the mix right in this Bill.

Sustainable Aviation Fuel Bill

Graham Leadbitter Excerpts

Consideration of Lords amendments
Tuesday 3rd March 2026 Commons Chamber

[Mr Perkins]

I can neither confirm nor deny what the hon. Gentleman says. Frankly, I am not certain about that—he may well be right. I was not seeking to create great division on this, although I do think my general point remains. None the less, as I say, I thank him for what he has said and for his support for the Bill. We have plenty of things to argue about; let us not dance on the head of a pin in this area where we are all agreed.

The Government are clearly committed to greater aviation expansion. The recent work of my Committee, the Environmental Audit Committee, has demonstrated that it is possible to achieve the Government’s ambitions to have that growth while protecting nature and the environment. However, the Committee has also demonstrated that that is not by any means inevitable, and that sustainable aviation fuel is one aspect that must play a growing role alongside a suite of other measures if the Government are to reduce carbon emissions from aviation while driving that passenger and economic growth. It is absolutely crucial that the Government take action not just on sustainable aviation fuel, but on the many other elements that will be necessary both to keep the Government’s promise and to keep them out of the courts and from being judicially reviewed. It is important that this is one of a number of measures.

[Graham Leadbitter (Moray West, Nairn and Strathspey) (SNP)]

The hon. Gentleman rightly points to the need for a suite of measures to deliver the Bill’s objectives and the overall reduction in fossil fuel usage by the aviation sector. One of the means of doing that is to massively ramp up green hydrogen production, which will have to happen over a number of years. I am sure that the hon. Member for Falkirk (Euan Stainbank), whom I have seen bobbing, will no doubt point to that. A quick way to kick-start that marketplace and boost sustainable aviation fuel would be to increase the amount of hydrogen that can be injected into the gas grid to 20%. The evidence is there to say that it would work. It would act as a massive kick-start for the industry. Does the hon. Gentleman agree?

[Mr Perkins]

The hon. Gentleman makes an interesting point—it is definitely something worth considering.

The Government have given an important commitment to meet their climate change and environmental targets at the same time as expanding airports and growing the economy, and I welcome that commitment. It is a hugely important promise, but it is also a huge challenge. Sustainable aviation fuel can deliver emissions savings compared with traditional kerosene fuel. Increasing its use is a vital piece of the puzzle in decarbonising aviation.

The revenue certainty mechanism introduced in the Bill will provide the minimum price guarantee for producers of SAF in the UK, so whoever was responsible for it, I welcome these amendments. The price certainty will encourage investor confidence in bringing commercial-scale SAF plans to the UK and bringing SAF production and jobs. Alongside that revenue certainty mechanism, the Government have introduced a SAF mandate: a legal obligation on fuel suppliers to the UK to provide an increasing proportion of SAF to airlines. That policy is also essential to driving the uptake of SAF.

What assessment has the Minister made of when these SAF mandates will be achieved? Does he think that they will be achieved in the next year? If not, at what point does he expect those mandates to be met? The Government do not believe that we need to follow the advice of the Climate Change Committee and see demand management alongside a suite of other measures as one of the approaches. Instead, they believe that we can get greater amounts of sustainable aviation fuel. Will my hon. Friend tell me how important it is to see the industry achieving these early mandates if we want to give confidence that they will be achieved in much greater numbers in the future?

Despite these welcome policies, the Environmental Audit Committee heard evidence—I think the Minister confirmed that today—that the UK would not be able to provide sufficient SAF to service the level that the Government expect the industry to use. We know that imported SAF is not currently recognised in UK carbon budgets as being a genuine reduction in emissions. Although I understand the Government have plans to include international aviation emissions within their carbon calculations, the UK has yet to formally legislate to include those emissions within the carbon budgets, despite both this and the previous Government agreeing to do so. Will the Minister confirm that the Government will prioritise parliamentary time to introduce the necessary legislation to formally include international aviation emissions within the UK carbon budgets?

The Environmental Audit Committee also heard evidence from the Whittle Laboratory at Cambridge University that, while moving to 25% of fuel usage to SAF would offer substantial emissions reductions, the reductions become much less certain beyond that point, because moving towards SAF could push up its price when compared with other sectors. That could lead to the potential of reduced availability of feedstocks for other sectors and a move beyond utilising waste products towards having to grow and cut down crops purely to serve the aviation sector. Therefore, if we go beyond 25% and start aiming for 50%, 60% and 70%, the certainty of this being an environmental and carbon reduction becomes much less certain. I wonder what assessment my hon. Friend has made of that research and whether he has visited the Whittle Laboratory. I also had the opportunity to listen to its modelling on this, so I wonder what he made of it.

Finally, will the Minister reassure me that he will not allow SAF production from feedstocks, potentially undermining the environmental sustainability and the emissions savings of SAF? Has he had any discussions with the Secretary of State for Energy, Security and Net Zero around the likely needs for the very same stock as part of our energy production in the future, particularly given the potential growth of data centres? Does the Government have a collective approach on the need for both sustainable aviation fuel and biofuels servicing our energy sector? With that, Madam Deputy Speaker, I will bring my comments to a close.
