Before we begin, I encourage Members to wear masks when they are not speaking. This is line with Government guidance and that of the House of Commons Commission. Please give each other and members of staff space when seated and when entering and leaving the Chamber.
That this House has considered decarbonising aviation.
It is a pleasure to see you in the Chair, Sir Gary. I thank colleagues for taking the time to participate in this important debate, which my constituents, and no doubt those of all Members, will be watching with interest. My constituents in Putney are under the flightpath and they have plenty of opportunity to have a close connection with planes.
If we are to achieve our net zero ambition and turn the tide in the fight against climate change, we need to fight on many fronts. Aviation is a front we simply cannot retreat from. I am sure the Minister is ready with a list of the ways in which sustainable aviation fuel is going to save the aviation industry, but I hope to hear more than that: about how we can incentivise alternative ways to travel, or not travel, and a new commitment to look again at Heathrow expansion, as it is not compatible with the decarbonisation strategy published in July. Sustainable aviation fuel alone will not mean that we can head off into a new era of guilt-free flying. We must also have a reduction in flights and an associated increase in public transport, if we are to achieve net zero at the necessary speed.
I congratulate the hon. Lady on securing the debate. Does she agree that one of the best ways of decarbonising aviation is by reducing demand and that one of the most effective ways of doing that would be through a frequent flyer levy? Given that just 15% of people take 70% of flights, a frequent flier levy would be a fair and effective way of reducing aviation demand.
I agree with the hon. Lady that we need to look at a range of ways to tackle carbon in the aviation industry. I am disappointed that the “Decarbonising Transport” paper does not include measures such as the one that she has recommended. Too often, sustainable aviation fuel is used to give the illusion of environmental action, but there is a danger of greenwashing because of an over-optimistic assessment of how quickly we can scale up alternative fuel use and how sustainable these fuels really are.
The aviation industry is vital and valued for travel, jobs, trade and connecting us to the world, but it is also responsible for about 7% of global warming and is, mile for mile, the most damaging way to travel for the climate.
I thank the hon. Lady for securing this important debate. Another factor that needs to be considered is how long aircraft can be used. These vehicles are built to last, so it takes significant time before operators need to replace them or swap them out for ones that are more environmentally friendly. We know that the pandemic has led to some airlines retiring their aircraft earlier than planned, so does she agree that the Government could provide financial incentives for airlines if they choose more sustainable aircraft in the future?
I agree that airlines need to be able to replace their aircraft to speed up the level of decarbonisation, so we need incentives for that as well.
A return flight from London to San Francisco emits around 5.5 tonnes of CO2 equivalent per person, which is more than twice the emissions produced by a family car in a year and about half the average carbon footprint of someone living in Britain. Even a return flight from London to Berlin emits around 0.6 tonnes of CO2 equivalent, which is three times the emissions saved from a whole year of recycling.
My constituents in Putney know this all too well. We live under a major global flightpath, so we know what it is like to have thousands of tonnes of CO2 dumped on us every day from above, and to have to suffer the noise from the aircraft. The bottom line is that to achieve net zero, moving to sustainable aviation fuel is essential, but this is an industry in its infancy. Millions of tonnes can currently be produced, but we need billons of tonnes of fuel to be produced every year to meet demand.
We cannot move to sustainable aviation fast enough, so reducing flights must be built into jet zero plans, but it is not at the moment. It will take at least two years for the airline industry to return to pre-covid levels. We should be taking this opportunity to have hard conversations with the aviation industry about sustainability in respect of not only the fuel used but the number of flights taken. We should not allow the Heathrow expansion and third runway plans to go ahead. We should make it easier, cheaper and quicker to take train journeys instead of short plane trips and build in incentives for train travel. France has banned short-haul internal flights where a train journey shorter than two and a half hours could be provided as an alternative. Where are the equivalent bold moves from the Government?
I was pleased to see the Government launch the long-awaited decarbonising transport and jet zero consultation strategies earlier this year. I was also pleased to see the “Green Fuels, Green Skies” competition have such a good take-up and produce such an innovative winner, and to see the first British Airways flight using sustainable aviation fuel just five days ago. However, I am disappointed that the Jet Zero Council has met only a handful of times since it was established last year. Just how committed is it to change within the industry? I am also disappointed with the decarbonising transport strategy. The aviation section is a house of cards: it rests on extremely optimistic assumptions and speculative technological breakthroughs, which are either in their infancy or do not yet exist. It could all fall apart very easily. There is very little policy basis.
It is a pleasure to serve under your chairmanship, Sir Gary.
I congratulate the hon. Member for Putney (Fleur Anderson), my constituency neighbour, on securing this really important debate. As her constituency neighbours mine, I obviously share many of her concerns about the flightpath, Heathrow expansion and the impact that unrestrained aviation growth might have on the health and welfare of people—not just my constituents, but people across the country.
I can probably do no better than to illuminate further some of the points that the hon. Member has already made so well. I will start with the Government’s jet zero strategy for aviation. She ably pointed out how the delivery of jet zero depends so heavily upon the development of new technology. As she said, what will we do if that technology is not developed? It seems very clear to me, and indeed it was recommended by the Climate Change Committee, that alongside the technological development that we all want to see, either of hydrogen engines or some other form of technology, we really must see some demand management of our airspace, of flights and of aviation.
The last time I had the opportunity to raise this matter with the Prime Minister and to ask him what he wanted to do about the ANPS, I asked him directly if he would amend it to rule out Heathrow expansion. I was very disappointed that he said it was “a private matter”. I do not think that it is a private matter. For all the reasons that the hon. Member for Putney laid out, it is of the utmost importance for everybody across this country that if we are serious about getting to net zero, and if jet zero is going to be a part of that, demand management for aviation has to play a role, because we cannot just depend on the development of new technology. The very first thing we must do, before anything else, is to rule out expansion at Heathrow airport, so I join the hon. Member for Putney and many other MPs—not just across west London, but across the country—in once more asking the Minister to review the ANPS.
The hon. Lady is making a powerful case about the jet zero strategy. Does she agree that that strategy is overly dependent on carbon offsets, and that increasingly, climate scientists are pointing out that carbon offsetting is actually very limited, given that all sectors in all countries need to get to real zero and there are limitations on how much carbon dioxide forests can absorb? Instead of playing accounting games, we should be treating the climate emergency as a real emergency.
The hon. Lady is absolutely right. More and more, I hear people talking about adapting to climate change instead of tackling it, and I am really concerned that people are doing exactly that, or thinking about exactly that: operational solutions to enable us to carry on exactly as we are, rather than tackling the problem at its root. This is not just about climate change; it is about biodiversity in all its forms, and it is so important that we come up with solutions that radically reduce carbon, rather than push it elsewhere and pretend it does not exist.
To sum up, the technological possibilities and what they might mean for our economy and skilled jobs right across the country are really exciting, but the Government must publish a proper strategy for how they plan to get there. If they want to prioritise hydrogen, we should make sure that we focus on green hydrogen, and on making sure that the production of hydrogen continues to be as carbon-free as possible. However, what I really want is for the Government to pursue a strategy of reducing demand alongside developing those technologies, and to take the opportunity offered to us by covid—the enforced changes to working patterns, and the facility we have all now gained for using Zoom for all manner of things, including parliamentary debates—to think about our approaches to travel, to really prioritise the travel that is necessary and to think seriously about how we are going to decarbonise aviation.
It is a pleasure to serve under your chairmanship today, Sir Gary. I rise to contribute to this debate as an aircraft engineer. There are precious few of us—or engineers of any description—in Parliament, and these technically challenging debates are sometimes the poorer for it. Others have spoken about the need to support airports, and I fully endorse that priority. That effort is led in this place largely by my hon. Friend the Member for Paisley and Renfrewshire North (Gavin Newlands), and I am sure he will touch on that topic later on. Similarly, we need to act on the pressing need to support aircraft manufacturing and maintenance in Scotland and the rest of these islands, recognising the tremendous expertise that exists in the sector and the value that it has for the economy.
In this debate, I wish to shine a light on design issues, especially the twin problems of realism and pace within the design dimension, which I feel are not being properly addressed, much less owned. The UK Government talk an average game when it comes to net zero, but the investment and the road map have been pushed out almost entirely to make space for political rhetoric, much of it hyperbole. Perhaps if we put a gun on a new sustainable prototype aircraft, the UK Government would get their act together. With just a fraction of the investment lavished on the Typhoon multi-role combat aircraft, UK taxpayers could have a real global competitive advantage in renewable aviation businesses all over these islands. The absence of investment leaves industry to do what it can, which is good up to a point, because it is the industry’s engineers and scientists who will get us out of the inertia of conventional propulsion systems consuming fossil fuels and into the next generation of passenger aircraft, but they will not do it without game-changing Government investment.
I invite the Minister to agree with me that in the effort to get beyond hydrocarbon propulsion, batteries are intensely limited in their role. With current battery technology, they will always be limited to only a few hundred miles, and even then battery aircraft are some way off being commercially available. They are somewhat of a distraction from the real prize of engineering a solution to medium and long-haul transportation.
I say to the hon. Member for Angus (Dave Doogan) that that was incredibly informative and really constructive. It was worth coming, if only for the entertainment. That was very good.
As the MP with Heathrow in his constituency, I obviously have a special interest. We have been through a brutal period over the past 18 months. It has been grim in terms of loss of jobs and the impact on the community. There are whole families who are dependent on work at the airport, and the situation has affected the local economy and the way of life and wellbeing of so many people.
My last conversation with the Chancellor before I stood down as shadow Chancellor was about the need to have an aviation strategy to deal with covid, and to build on that for the long term to tackle climate change. I said, although I was not listened to, that the best thing would be to get the industry together—employers, companies, unions and local communities. I said it was better to listen to the unions, because they are more independent of the fight that will go on between individual companies. The unions were already looking at how we could come through the covid crisis and be honest with people about the future. We cannot return to the way it was; we cannot return to a policy of continuous expansion. That cannot happen if we are really going to tackle climate change.
I have five points to make, and I am sorry if I bore people by repeating them in debate after debate. First, there is the principle of doing no further harm. The third runway will set us back and, as we go into COP, undermine people’s confidence that we are serious about tackling climate change. Let me give some background to the Prime Minister saying that he would lie down in front of the bulldozers. At his first election as the MP for Uxbridge and South Ruislip, I asked at my count, which was before his, “Will he make the same commitment as his predecessor, John Randall”—who people may remember is now in the House of Lords—“who said he would lie down in front of the bulldozers with me?” Of course, Boris could not help himself. As soon as the count was over, he got up and said, “I’ll be with you, John.” Bizarrely, when the vote came up in the House of Commons, he was on a one-day visit to Afghanistan. I suppose that was pure coincidence.
I thank the hon. Member for Putney (Fleur Anderson) for setting the scene for this debate. There have been some incredible contributions so far, but I want to take a slightly different angle. I agree with the points that other hon. Members have made, and I hope the Minister’s response will encompass some of my thoughts about how we move forward.
I am the MP for Strangford, as people know—if they do not know that after 10 or 11 years, there is something seriously wrong in this place—and I am a frequent flier because I have to be. The fact is that the Irish sea divides us water-wise—the Northern Ireland protocol also divides us, but I will not mention that—so for me to come here to work, I have to leave from Belfast City airport and fly over here. The journey from leaving the office to getting here takes about three and a half hours. The flight takes approximately an hour. I do that every week, and so do other right hon. and hon. Members—colleagues and friends in my party and others. The hon. Members from the Social Democratic and Labour party and the Alliance party travel in the same way because it gets us here within a certain period of time. The alternatives are to go by boat or take the ferry over and drive down. We could do that if we had two or three days to spare, but it eats into our time as constituency MPs. I am a very active one, as others in this House are—I am not saying I am the only one. The fact is that our time is precious and we use it accordingly, so I am a frequent flier because I have to be.
On the back of the Secretary of State’s statement to the House yesterday, we heard about the aviation industry’s worries about its ability to recover from the economic impact of the past year or so. Obviously, it is equally important that it contributes to the net zero goal. Does the hon. Gentleman agree that the Government must ensure that it is properly supported in its work to decarbonise and is not faced with further unaffordable costs?

To be clear, it is important that we invest in and enable technological innovation and breakthrough; we will not be able to achieve net zero without it. However, the focus should be on what is actually possible and can be delivered now. We need concrete policy, not a wing and a prayer. For example, the Climate Change Committee progress report recommends aviation tax reform to address the imbalances between aviation and surface transport. Will the Minister comment on whether there are plans to look into that?
Can we rely on alternative fuels? In 2010, the aviation industry pledged to source 10% of its fuels from sustainable sources by 2020—so far, so good—yet by 2018, it had managed to source a grand total of 0.002%. Sustainable aviation fuel production today is still less than 1% of overall jet fuel supply, despite being pitched by the industry as the panacea for decarbonisation. It is a wonderful feat of science and technology that the first UK commercial-scale alcohol-to-jet fuel facility has recently been commissioned to be built in Wales. However, the current global target for approximately 50% alternative jet fuel use by 2050 would require three new biojet fuel refineries to be built every single month for the next 30 years. Today, there are just two facilities.
The Government are putting their faith in the market, but the market is not delivering at the pace required to respond to the climate emergency. Airbus is developing a hydrogen plane, which may enter service in 2035, and electric flight relies on batteries that are far too heavy to be used even for short haul, let alone for long haul, so we cannot rely on those. We need a plan B. We need to know what additional policy measures will be required to deliver net zero aviation should the promised technological breakthrough not occur.
That brings me to Heathrow expansion and the need for robust plans to reduce demand for flights. To be serious about decarbonising aviation, the Government must rule out plans for expanding Heathrow. Heathrow is the largest single polluter in the UK and its emissions account for half of all UK aviation emissions. Its expansion proposals allow for 260,000 additional flights per year, on top of the existing 480,000. That would pump between 8 and 9 megatonnes of extra carbon per year into our atmosphere. It will require operational restrictions at other UK airports as well, if the UK is to stay within the carbon budget. That is hardly levelling up. In fact, even the mere act of constructing the runway and the works associated with that are expected to result in an additional 3.7 megatonnes of CO2 emissions up to 2050. Moreover, neither Heathrow nor the Department for Transport have comprehensively considered the non-CO2 impacts of Heathrow’s expansion proposals, which would have a significant impact on the climate.
The long-haul journeys that make up 80% of aviation emissions from Heathrow, and that would make up the overwhelming majority of the additional 260,000 flights per year that would depart from the expanded Heathrow, will not be affected at all by the technological breakthrough in sustainable aviation fuel. There is no avoiding it: expanding Heathrow will guarantee a huge increase in kerosene burn, and the chances of the technological breakthrough needed are slim indeed.
I am sure that many colleagues here in Westminster Hall have followed the legal wrangling and the twists and turns surrounding the third runway. Frankly, this is a question that should never have entered the courts—why has it even got there? Any Government who were serious about achieving net zero would not entertain for a second the notion of an expanded Heathrow. Such a notion is fundamentally at odds with the Government’s own climate commitments and with the Environment Bill that they hope—one day—to pass. It is embarrassing that these plans were again given the green light in the year that we are hosting COP26, and that is not even considering the impact of the noise and the increased carbon dump over the green spaces and people of constituencies such as my constituency of Putney.
It is really simple: either Heathrow can be expanded or net zero aviation can be pursued. It is not possible to have both. At the very least, the Government should initiate a review of the airports national policy statement. However, if they are serious about decarbonising aviation, I hope that the Minister who is here in Westminster Hall today will announce that they will rule out Heathrow expansion all together.
I conclude by putting three questions to the Minister. First, what is the Jet Zero Council’s plan B? If the technological breakthroughs do not happen and sustainable aviation fuel cannot be produced and delivered quickly enough, then what? Secondly, why is the Department for Transport refusing to consider how to disincentivise frequent business travel by plane and make it easier, quicker and cheaper to take the train for short journeys instead of flying, and to reduce long-haul journeys, as was recommended by the Climate Change Committee in its 2021 progress report?
Finally, will the Minister commit to review the ANPS before COP26 later this year, rather than waiting until the jet zero strategy is finalised? Will he also commit to including an assessment of Heathrow expansion in that review? And will he join me and the Prime Minister in lying down in front of the bulldozers should the policy statement remain in place?
The climate crisis is here; it is now and it is real. There is no room for conjecture, complacency or cop-outs. Decarbonising aviation requires decisive action now, not deferred solutions that may not even come to pass. I really hope that the Minister listens closely to the whole of the debate today and to the concerns that are raised, and ensures that the jet zero strategy is realistic and consistent, and contains the bold policy interventions required to deliver our decarbonisation.
However, I am not pessimistic about the possibility of developing new technologies. I have had some really interesting conversations with people who work in this space, and it seems to me that the prospect of hydrogen powering aircraft in the future is not just a very real possibility, but is actually happening. I have also heard tell of electric flights, and have been invited to go on one. I have politely declined so far. I would like that technology to be a little more developed first—I have heard about those heavy batteries.
It seems to me that there is a great opportunity here for the UK to be right at the front of transport technology. We are a developed economy; we are an island, for whom international travel is critical; and we have the technology, the engineering capability and the will to do this. I believe that decarbonised aviation, alongside many of the other technologies that we are developing to meet the challenge of climate change, can be at the forefront of delivering the green jobs that will be so essential to our sustainable economy in the near future.
The Minister will know that the trouble with using batteries, not jet fuel, is that a craft that sets off with 10 tonnes of batteries will still have 10 tonnes of batteries at its destination. By all means, let us invest in short- haul regional aircraft—locked-up, prototype-tested, type-approved—and get them into service, if for no other reason than that we can then shift the focus on what we really need to deliver, which is a wholesale reimagining of long and medium-haul travel.
The rest of the UK could learn from the extraordinary work being led by Highlands and Islands Airports Ltd, serving Orkney and Shetland and assisting in the development and proving of short-range commercial electric aircraft. Nobody—certainly not me—doubts the potency of lithium-ion-powered aircraft, but nobody has overcome the critical weight and duration conundrums yet.
I know the Minister will not mind my pointing out that, like me, he is a bit of an aviation geek. I therefore have no hesitation in highlighting aircraft such as the de Havilland Comet, the Fairey Rotodyne, the Harrier Jump Jet and the Avro Vulcan—aircraft developed on these islands that represented a quantum leap in aircraft design and performance—all of which were facilitated by colossal Government investment. Where is that investment now? I do not know how much Government investment went into the now terminated Airbus/Rolls-Royce E-Fan X, which substituted one turbo fan on a BAE 146 regional jet for an electric fan powered by a battery linked to a gas turbine onboard generator. It was not the last word in outside-the-box thinking, but I am advised by Rolls-Royce that it was a valuable test bed for high-powered electrical architecture on board aircraft. Other Members have touched on hydrogen, and my personal view is that that is the route out for us. I invite the Minister to set out how he is going to facilitate that.
Before COP takes place, we need a clear statement opposing the third runway expansion at Heathrow. It is the iconic battleground in this country—and, in fact, in Europe overall—for tackling climate change. I welcomed Climate Camp into my constituency and it turned the third runway campaign from an nimbyist issue into a global one through the publicity and campaigning that took place. Climate Camp was 1,000 people turning up overnight, camping for a week and demonstrating and so on. It transformed the whole debate, but it will be insignificant in comparison with the protests that will take place if the Government try to force through a third runway, so we need a clear statement.
Secondly, we need to minimise the existing harms. That means managing demand, as the hon. Member for Brighton, Pavilion (Caroline Lucas) said. The best way to manage demand is, to be frank, through taxation, including VAT and fuel duty, and through frequent flier policies. We should also be assessing whether, in the world of Zoom and Teams, the level of business travel using aviation is absolutely necessary. It behoves us all to question all our transport undertakings, but the Government need to publish guidelines to discourage unnecessary business travel.
Thirdly, as the hon. Member for Angus said, we need a scale of investment in research and development that we have just not seen under this Government or previous Governments, whose policies have been more about predict and provide to meet escalating demand. We now need a scale of investment in research and development in alternative fuels, including batteries enabling short-haul flights, which undoubtedly will be developed. I understand where the hon. Gentleman is coming from—he knows much more than me—but I think that with such investment, we have in our universities and research institutes the engineering creativity to be world leaders on that front. I am old enough to remember the incredible work that was done on engines, including the RB211 up in Barnoldswick, where I worked at the time.
As we develop new methods, the Government then need to step in, as they did with cars, with some form of aviation scrappage scheme. Sometimes I resent handing over money to some of those companies because, as we have seen during the covid crisis, they have used it not necessarily to support the sector or the local economy, but to maximise their profits. A well-constructed scrappage scheme was undertaken—sometimes it is difficult to mention the name—by Peter Mandelson, and it was incredibly successful in transforming the environmental effect of the car industry. That is needed.
Finally, I will make a local plea: we need a just transition. If we are serious about a just transition, it means supporting the aviation communities that surround airports—in my constituency, that means Heathrow, but there are others. What they need now is support to develop alternative economies for the future.
One of the things that I suggested to the Chancellor before I stood down from the Front Bench is that, for my constituents in particular, but also for outer London, west London and all the other aviation communities, we need an individual taskforce bringing together the Government, local authorities, local communities, trade unions and the companies themselves to start planning the alternative skills training that is needed, the alternative investment, and other forms of logistics, including aviation and other employment opportunities. In that way, we can build confidence in the idea that we can decarbonise the aviation sector. At the moment, I do not think people have that confidence.
I make this plea: we are running out of time, and I do not want to keep doing this every year. This debate is like a hardy perennial. I do not want us to keep turning up and having this debate without seeing an awful lot of progress.
