Sustainable Aviation Fuel Bill

Graham Leadbitter Excerpts

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.

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.
