Sustainable Aviation Fuel Bill

Nusrat Ghani Excerpts

2nd reading
Wednesday 11th June 2025 Commons Chamber

[Heidi Alexander]

Supply is constrained at the moment; the UK has one commercial production facility, in Immingham. We need to build investor confidence to commercialise some of the sustainable aviation fuel demonstration projects around the country. More supply and lower prices are good for the aviation sector and, ultimately, good for those who wish to fly.

I think it is worth taking a moment to reiterate what is at stake. When UK production of low-carbon fuels is up and running, it could support up to 15,000 green jobs, contribute £5 billion a year to our economy, and deliver clean and secure energy. What is more, fulfilling the SAF mandate could save up to 2.7 megatonnes of carbon dioxide equivalent a year by 2030. Seizing those opportunities will ensure that we deliver on our bold plan for change and that the UK and our world-class aviation sector are leading the way in the race towards sustainable flight.

This country cannot be open for business, open to investment and open to growth yet have a closed mind when it comes to international connectivity. The Bill is a clear signal that we will not accept false trade-offs that pit aviation’s growth against our commitments to net zero. We can and must do both. We have the opportunity of a lifetime and, I believe, a moral mission to future-proof aviation. When the sector succeeds, it is not only a source of growth, through trade, business and tourism, but a source of joy, aspiration and opportunity. It is as vital today as it will be for future generations. Their need to fly, explore the world and do business requires us to act now. That is what the Bill does, and I commend it to the House.

[Madam Deputy Speaker (Ms Nusrat Ghani)]

I call the shadow Secretary of State.

[Gareth Bacon (Orpington) (Con)]

Let me begin by setting out an unambiguous truth: aviation is vital to the British economy. It is a cornerstone of our national infrastructure, our competitiveness and our connectivity.

When it comes to the impact of aviation on our economy, the figures speak for themselves. Aviation contributes £52 billion to UK GDP, supporting over 960,000 jobs across the country. That includes 341,000 people working directly in aviation—from air traffic controllers to aerospace engineers—350,000 jobs in the supply chain, and another 269,000 supported through consumer spending. Aviation also delivers nearly £8.7 billion in tax revenues, and aerospace manufacturing adds a further £9 billion directly to GDP, plus over £10 billion more when including its supply chains. Some 197 million passengers and 2 million tonnes of freight move through our airports each year. The economic case is therefore unanswerable. In short, we must all support this thriving industry with clear benefits to the country.

The Conservative party has always recognised the strategic importance of aviation, but, unlike the current Government, we understand the damage that can be done with poor policy choices—I regret to say that we have seen plenty of that from the Labour Government over the past year. Alongside their national insurance jobs tax, which is putting pressure on businesses and threatens to leave working people £3,500 a year worse off, Labour’s decision to hike air passenger duty threatens the vitality of this thriving industry. The Office for Budget Responsibility confirms that rises planned by the Chancellor of the Exchequer will raise an extra £555 million in taxes over five years, pushing up the costs for businesses and passengers alike.

In a speech that will have a lot of common ground with the Secretary of State’s speech, I regret to say that Labour’s handling of its professed desire to expand aviation raises more questions than answers. The decision to approve a second terminal at Luton airport, which we support, will be judicially reviewed. The proposal for a second runway at Gatwick has been kicked down the road for surprising reasons, to say the least, and the supposed support for a third runway at Heathrow is no more credible. The Chancellor has promised that the latter proposal will be operational by 2035, with spades in the ground in this Parliament, but that ambition looks very far-fetched, and there are substantial logistical and financial barriers to its construction. So far, the Government have provided no solutions on those points, so we will watch developments in the next few weeks with considerable interest.

It is against that backdrop that we come to the Bill before us. When we entered opposition, we made it clear that we would not oppose the Government just for the sake of it. We made it clear that where the Government’s choices would benefit the country or the economy, we would welcome them. That is why we will not seek to divide the House on this legislation on Second Reading. This Bill is a logical follow-on from the statutory instrument passed in September last year that established the SAF mandate, the first stage of which came into effect in January. Having mandated that airlines will be required to use a specified percentage of SAF—2% this year, rising to 10% in 2030 and 22% in 2040—it is logical to take steps to ensure adequate levels of locally produced fuel.

While the mandate requires the consumption of SAF, it is a new technology, and its production carries a high risk for investors. Encouraging the development of the plants required to produce this fuel is the purpose of this Bill and, to a very large degree, it is a continuation of the policy of the previous Government. In 2023, it was the last Government who committed to an industry-funded revenue certainty mechanism to support UK-based SAF production. In early 2024 we published the detail, with plans for a guaranteed strike price model to give price certainty to SAF producers. I hear the Minister say, “You didn’t do it!” He is completely correct, because unfortunately there was something called a general election that followed shortly after.

As the Secretary of State has outlined, under this model, producers will be topped up when the market price falls below a guaranteed strike price; when the market price rises above, they will pay it back. The system mirrors the successful contracts for difference model in offshore wind, and the economic benefits could be considerable. A cost-benefit analysis produced by the Department for Transport before the general election suggested that the SAF industry could add more than £1.8 billion to the economy and create more than 10,000 jobs in the country, but, more fundamentally, SAF is a product of what we know to work. As the Secretary of State said in her speech, it can be blended with conventional Jet A-1, used in existing aircraft and refuelled at existing airports. The capability exists. The challenge is not scientific; it is economic. That is why the concept of a revenue certainty mechanism was one of the six pillars in the previous Government’s jet zero strategy, and, as the Secretary of State outlined, the introduction of a revenue certainty mechanism has wide support in the aviation industry.

Let me be clear: while we will not oppose the legislation this evening, we will carefully scrutinise it as it progresses through the House. In that spirit, I will put some questions to the Minister, which I hope he will address in his summing up. The first is about passengers. In the press release announcing the Bill, the Government said that the revenue certainty mechanism would keep ticket price changes minimal:

“Keeping fluctuations to £1.50 a year on average.”

The Secretary of State said the same in her speech. Perhaps in his speech the Minister could outline what this figure is based on. Do the Government stand by it? Is it a commitment, or a rough estimate?

The second question is about what type of SAF the Government favour and how it will be produced. While the SAF mandate permits the production and use of hydroprocessed esters and fatty acids SAF in the early years of the mandate, and also contains a small but increasing requirement for power-to-liquid SAF in later years, the bulk of the SAF to be developed and used under the terms of the mandate is second generation SAF, which is to be made from municipal waste, non-edible crops and woody biomass. The UK is a small island, with insufficient spare land to enjoy self-sufficient food security or to grow new forests at scale. Does the Minister think we will be self-sufficient? If not, what proportion of the ingredients necessary for making second generation SAF does the Minister think we will need to import?

Relatedly, the HEFA cap comes into force incrementally from 2027, despite there currently being no domestic production of second generation SAF in the UK and low levels of second generation SAF produced globally, removing the opportunity to source mandated volumes through imports. This risks making the costs of hitting SAF mandate targets very high indeed, because suppliers will soon be forced to buy out of their mandate obligations—a significant cost that will be passed on to the airlines and, ultimately, to passengers without delivering any decarbonisation benefit at all. Will the Government consider revising the timelines for phasing out HEFA SAF to bring them more in line with the timescales for domestic second generation SAF production, in order to minimise the costs for passengers?

The next area of interest is planning. The plants in which the Government are seeking to encourage investment will be large, and—as the Minister no doubt knows—large developments tend to attract a lot of local opposition, often leading to planning inquiries, judicial reviews, vast expense and years of delay before any construction work begins. If this does not change, the revenue certainty mechanism may not be sufficient to attract investors, so what will the Government do to minimise delays in the planning process?

I turn now to timescales. When will the first contracts be awarded under the RCM? Will there be a timetable for reaching full mandate compliance? As my right hon. Friend the Member for Goole and Pocklington (David Davis)—who is no longer in his place—touched on, the issue of the strike price is critical to the success of the proposal. What criteria will be used to set the strike price? Will the methodology be published, and will there be regular reviews? Finally, will the Government commit to regular reporting to Parliament on industry take-up, production capacity and cost trajectory, to ensure that they remain accountable for the Bill over time?

The importance of this Bill is clear. Backing UK production of sustainable aviation fuel is necessary if we are to meet our net zero goals without undermining the competitiveness of the aviation sector. However, let me be clear: as the Bill moves through the House, we will continue to look closely at the detail and press for changes where necessary, where improvements can be made to ensure that the scheme delivers on its promise.

[Madam Deputy Speaker (Ms Nusrat Ghani)]

I call the Chair of the Transport Committee.

--- Later in debate ---

[Luke Taylor (Sutton and Cheam) (LD)]

As chair of the all-party parliamentary group for the future of aviation, travel and aerospace, I very much welcome this step to push the aviation industry into a sustainable future. I encourage Members to join the APPG and come along to our meetings if they want to find out more about sustainability and the future of aviation. I worked in the aviation industry for 16 years before being elected to this place, and I studied aeronautical engineering for four years before that, so it would have been remiss of me not to come to the Chamber today to share with hon. Members my expertise on the subject, but I will try not bore them.

I welcome the support for future technology and the investment previously announced by the Government. We have massive and historical expertise in aviation here in Great Britain and Northern Ireland and we really must grasp the opportunity to develop those skills and that technology further. It is an incredible opportunity for UK plc and we need to grasp it. I want to pick up on a comment by the Secretary of State in her opening speech about airspace modernisation, because it is relevant to the discussion. We must grasp the opportunities of airspace modernisation, which have the potential, as she mentioned, to deliver shorter, more direct and more efficient flight routes. But as MPs, we must engage with the process. We must understand and learn about how that is happening around us. It is inevitable, but we must get the best for our communities. We must understand and engage with that process as it goes along. It is an incredible opportunity.

Over the past few months, the APPG has been hearing about the technologies that we have today. Of particular interest is ZeroAvia, which is already flying a hydrogen-electric, zero-emission aircraft in the UK—it has a hydrogen fuel cell with electrical propulsion, which offers completely zero-emission flight. As my hon. Friend the Member for Wimbledon (Mr Kohler) mentioned, this is only a stepping stone to the truly zero-emission flight that we really need to capture.

If hon. Members will forgive me for boring them slightly, the Breguet range equations that I learnt about for my degree are the reason why an Airbus A380 will take off from London at 580 tonnes and land in Sydney at around 340 tonnes. The burning of fuel throughout the journey means that it is able to maintain the range and maintain the flight levels that the burning of the fuel and the reduction in the weight require. That is one reason why liquid fuel will almost always be required for very long-haul flights, no matter how far we progress with hydrogen and electrical power plants for short and medium-haul flights.

That amplifies the need not just for the current second-generation SAF production, but for looking at alternative fuel sources such as algae-derived SAF. Others have correctly made the point about the reduction in residual waste, which is the current fuel source for a lot of biodiesel for the development of SAF. As those sources decrease and the cost potentially increases, we need to look at truly zero-carbon sources of SAF.

I will not bore hon. Members more. In closing, I will just echo the words of my hon. Friend the Member for Wimbledon and of my party and encourage the Minister to go further and faster to achieve truly zero-carbon and lower-noise aviation technology so that we can continue to enjoy the incredible freedoms and opportunities in both economic activity—jobs, skills and trade—and the broadened horizons that aviation has offered us for more than a century. Long may it continue.

[Madam Deputy Speaker (Ms Nusrat Ghani)]

Order. I will now announce the result of today’s deferred Division on the draft Contracts for Difference (Miscellaneous Amendments) (No. 2) Regulations 2025. The Ayes were 350 and the Noes were 176, so the Ayes have it.

[The Division list is published at the end of today’s debates.]

[Amanda Hack (North West Leicestershire) (Lab)]

It has been said by the Secretary of State and echoed across the Chamber that the UK has a world-class aviation sector that is key to growth in our economy. I welcome the introduction of the Bill as it will provide certainty for producers of sustainable aviation fuel, allowing the sector to grow and invest.

We all know the benefits that airports have for our communities, which is why my hon. Friends the Members for Doncaster Central (Sally Jameson) and for Doncaster East and the Isle of Axholme (Lee Pitcher) will welcome the Chancellor’s investment in Doncaster Sheffield. When we think about airports, we may automatically think about Heathrow, Gatwick, Luton, Birmingham and Manchester. However, as East Midlands airport is in my constituency of North West Leicestershire, it will be no surprise to anyone here that that is the airport I automatically think about.

The airport provides huge benefits to my local economy, as well as making an important contribution to the wider UK economy. As the second largest air freight terminal in the UK, East Midlands serves as the hub for DHL, UPS, FedEx and Royal Mail. This growth is backed by investment in the nearby east midlands rail hub, which transports our goods from port to port. In addition, the airport serves as a base for RVL, a specialist airline that provides support to the Environment Agency and the Maritime and Coastguard Agency. The transition to sustainable aviation fuel is going to be key if those organisations are to grasp the nettle on net zero.

My airport also serves millions of passengers every year, with the likes of Jet2, easyJet and Tui operating out of it, supporting my constituents and those from those across the midlands to take a well-deserved holiday. Having met representatives of Jet2 recently, I know that there is huge support for the introduction of the revenue certainty mechanism, and it will be interesting to hear more about the transitional arrangements to ensure that airlines such as Jet2 have the fuel they need to decarbonise and meet the mandated mix over the short term, as well as to see the SAF industry develop for the future.

As East Midlands airport’s thriving cargo facility extends to meet the demands of exporters from across the UK, cutting greenhouse gas emissions via sustainable aviation fuel will not only have significant benefits for net zero, but will put an estimated £5 billion a year back into our economy by 2050. It will also create additional jobs, securing a long-term sustainable future for the industry. It also puts forward a clear commitment to jobs at the airport, which will benefit my constituents and those of neighbouring MPs in the east midlands. I would welcome assurances from the Minister that North West Leicestershire will see the full strength of these training and work opportunities when they come about, because we have a lot to offer.

I know that the measures in this Bill, alongside the work announced to modernise airspace, will be welcomed by the sector. May I take this opportunity to invite the Minister to the 60th birthday party of East Midlands airport on 21 July?

[Madam Deputy Speaker (Ms Nusrat Ghani)]

I notice that that was an exclusive invitation just to the Minister.

[Luke Taylor]

I would challenge the hon. Member’s commitment to aviation spotting if, during university, he did not take a date to the final approach at Heathrow airport and have her observing the flights coming in for a good two hours. He may be a geek, but he is not quite there yet.

[Madam Deputy Speaker]

It would rather depend on whether the date ended up marrying him, wouldn’t it?

[Luke Myer (Middlesbrough South and East Cleveland) (Lab)]

I welcome the Bill, particularly the introduction of the revenue certainty mechanism, which is not only a sensible intervention but a timely one. It gives investors clarity, it gives producers confidence and it gives communities such as mine a sense that this transition will bring jobs rather than take them away. I thank Ministers for listening not only to the sector but to those of us who represent Teesside.

In our region, we have a number of producers with an interest in scaling up SAF production—principally Alfanar, which has already invested £2.5 billion in our region and wants to go much further by building a brand-new plant that will create 2,300 construction jobs and 300 permanent jobs. Alfanar is not alone, however; we also have Iogen, Willis, Nova Pangaea, Abundia, Arcadia and many active producers or others looking to scale up—serious players with serious plans. I spoke to one earlier this week; it said that the Bill is exactly what the industry is looking for.

May I put just a couple of questions to the Minister? What those producers need now is confidence that enabling work for final investment decisions can begin, ideally before the Bill completes its full legislative journey. Of course, there is a precedent for that in the Energy Act 2023. What engagement will the Minister have with the Department for Energy Security and Net Zero on the carbon capture track project. I know that a number of the producers are keen to benefit from track 1 expansion, so producing those two things in train seems like a sensible thing to do, and I hope that there is cross-departmental engagement.

Ultimately, I thank the Government and urge them to move at pace to deliver the jobs that we want for the industry in our region. I want to ensure that young people watching from working-class communities across Teesside know that these are not abstract opportunities that are distant from them, but opportunities for them that they can get into—like our expansion in skills training. This sector can be transformative for the Tees valley region—not only for Middlesbrough but for Redcar and Cleveland, Stockton, Darlington and Hartlepool. Our area suffered industrial decline for many decades, but now we are seeing new life and new industry. Finally, Teesside is taking off.

[Madam Deputy Speaker (Ms Nusrat Ghani)]

I call Chris McDonald for the final Back-Bench contribution.

--- Later in debate ---

[Chris McDonald]

I agree. Whether it is in Sunderland or, as I mentioned, the north-west and down in south Wales, we will see jobs in the supply chain throughout all this work. It will also benefit Heathrow and our other major airport hubs.

I thought it might be useful to make a few comments about why I believe SAF is the solution. The hon. Member for Sutton and Cheam (Luke Taylor) gave a great description of why the flight range equations essentially drive us in the direction of sustainable aviation fuel. Electrification certainly would be possible for short-haul flights, but the hydrogen simply does not have the density. As I think the hon. Gentleman also said, infrastructure is important—we heard that from the Secretary of State in her opening statement—because planes take off from one place, but they land somewhere else, and they need to be able to refuel there too.

Sustainable aviation fuel is certainly the right approach, but a couple of Members raised concerns in the debate about the raw materials for feedstock—my hon. Friend the Member for Brentford and Isleworth (Ruth Cadbury) raised that issue. The hon. Member for Mid Bedfordshire (Blake Stephenson) said that he had learned about second-generation sustainable aviation fuels; it is probably just as well that he is not in his place, because I might blow his mind when I talk about third-generation and fourth-generation sustainable aviation fuels.

Essentially, there are concerns about the raw materials and municipal waste. Although the amount of waste per person will decline, a lot of it is put into energy from waste plants, and the new investments are really about future generations of SAF. We have heard about biomass. If that biomass is not from a feedstock, perhaps that verges into the second generation, but it is third-generation and fourth-generation sustainable aviation fuel that will enable us to scale up this industry. That will open it up to the direct combination of carbon dioxide and hydrogen using green electricity, which will enable us to scale it up. An abundant supply of those raw materials is needed, which is why I am so confident that we will see the industry spread around the whole of the UK.

Why do I say Billingham will become the UK and European centre for this work? There is a justification. Teesside already produces 50% of the UK’s hydrogen, and the chemicals cluster there is well-known for producing pharmaceuticals for fertilisers and various other chemicals. We produced synthetic petrol in Billingham in the 1930s, and we produced synthetic jet fuel there in the 1940s for the Royal Air Force during the second world war. I say that not to imply in some way that we still have the skillset—many of those people are quite rightly enjoying their retirement, or have perhaps moved on from that—but to demonstrate to the House that there is not a big technological risk associated with this technology. Third-generation SAF will rely on the Fischer-Tropsch process, which has been around for 100 years.

In fact, when I talk to investors in the industry and ask them what the big risks are, they highlight economic risks—with which the Government are getting to grips right now through this legislation—and political risk, which is about the consistency of Government policy. As I mentioned earlier, the biggest threat to these jobs and to this industry is the ideology of the Reform party. As we see the jobs and investment, I am confident that people in my local community will vote for jobs and investment in the future as well.

As such, I warmly welcome this legislation. I very much look forward to the day when I can welcome right hon. and hon. Members to Teesside international airport, and enjoy a drink with them in the bar before we jet off to Alicante for our holidays.

[Madam Deputy Speaker (Ms Nusrat Ghani)]

I call the shadow Minister.
