Sustainable Aviation Fuel Bill

The UK has a real opportunity to lead the world in the production of sustainable aviation fuels, and this Bill aims to provide the investment certainty needed to scale up domestic SAF production and achieve just that.

My constituency is located a stone’s throw from London Luton airport. It is a rapidly expanding regional airport, and that expansion will bring with it huge economic benefits, including jobs for thousands of my constituents and better connections for business and leisure. Indeed, airport expansion will help to bring millions of people to the Universal UK theme park—which I have to mention every time I stand up—and play a key role in driving local economic growth. But just as it is important to support the growth of airports such as Luton, it is important that expansion happens as sustainably as possible to ensure that we get as many of the benefits, and as few of the harms, as possible.

This is the subject of a current Environmental Audit Committee inquiry, which I was pleased to secure, investigating how the Government can deliver airport expansion while meeting their legally binding climate targets. Some, such as the Climate Change Committee, say that it is not possible, and the Government need to square that circle. With around 7% of greenhouse gases derived from aviation in the UK, we should not underestimate the challenge, but it is clear to me that sustainable aviation fuels are an important piece of the jigsaw.

In my constituency of Mid Bedfordshire, Cranfield University and local industry are already working at the cutting edge of developing new technologies in this area. I have heard from them and other experts about the potential of British-made sustainable aviation fuels. I have even learned about second-generation SAF—not something that I thought I would get into this time last year—which turns the waste we all put in our black bins every week into the fuel that powers us to adventures abroad. That is a remarkable thing, and I am glad to have learned about it since coming into the House. If we get sustainable aviation fuels right, we can create and support thousands of highly skilled jobs in places such as Cranfield.

Doing more to stimulate the development of sustainable aviation fuels is an obvious route to economic growth, so will the Minister reflect on our global market position, explain how the mechanism compares with other approaches, and give an assurance that the measures in the Bill will be enough to avoid the UK aviation industry needing to import SAF from abroad? It would be a huge missed opportunity to later find that this mechanism and related policies have not been ambitious enough, leaving foreign countries to benefit from domestic mandates.

One thing that strikes me immediately as worthy of more thought—the Minister may wish to comment—is black bin waste. Taking waste that was heading to landfill and instead using it to power us into the sky would seem to be a simple way forward, although whether there is enough of it is another matter. I declare my interest as a Central Bedfordshire councillor, but will the Minister consider the merits of including, in this Bill or elsewhere, a requirement for the Secretary of State to provide local authorities with guidance on how they can take advantage of this opportunity to help in the national effort to scale up production? Unless it is financially prohibitive for them to do so, would it not be sensible and pragmatic to let them use our household waste in this way, rather than let it head to landfill or local incinerators?

Finally, I have a few questions for the Minister on the costs of aviation travel. As we all know, times are tight for many of our constituents. UK air passenger duty is the world’s highest tax levied on airline passengers, and following the autumn Budget, the OBR forecasts that it will increase 9% a year on average to a whopping £6.5 billion in 2029-30. On top of that, it is estimated that the impact of the Bill through the levy and administration costs will raise the cost of a ticket to travel. I know Ministers say that it is a modest increase, but that is why some may prefer the Government to use an alternative funding mechanism, such as the industry’s contribution to the UK emissions trading scheme. I am not saying that the Government should take that approach, but it would be worthwhile for them to explain why they have taken the approach they have. Reflecting on the fact that the costs of the Bill come on top of the increase to air passenger duty in the autumn Budget, will the Minister provide an assurance that the Bill will not clobber our hard-working constituents with yet higher prices when they jet off on their family holiday?
