Sustainable Aviation Fuel Bill

There is more detailed design work to do on all that, and we will work alongside industry to ensure that we have a workable proposition.

The mechanism boosts SAF production and gives investors confidence in the UK by addressing one of the biggest barriers to investment: the lack of a clear, predictable market price for SAF. That starts with a guaranteed strike price agreed between a Government-owned counterparty and the SAF producer. If SAF is sold for under that price, the counterparty will pay the difference to the producer. If SAF is sold for above that price, the producer will pay the difference to the counterparty.

The revenue certainty mechanism will be funded by industry, specifically through a levy on aviation fuel suppliers. That makes sense for two reasons. First, it is the industry that will benefit from more and cheaper SAF production, so it is only right that industry, and not the taxpayer, should fund it. Secondly, placing the levy higher up the supply chain spreads costs across the sector and is the least burdensome option. It is important to note that the revenue certainty mechanism will not be indefinite. It will be targeted and time-limited, helping to get first-of-a-kind UK projects off the ground. The Bill’s sunset clause means that we can offer contracts only for 10 years, unless it is extended via the affirmative procedure. We will have a firm grip on costs throughout. We will decide the number and duration of contracts, limit support to a predetermined volume of SAF and negotiate acceptable strike prices. There is no obligation on the Government to enter into a defined number of contracts or to agree contracts at any cost.

I know that some hon. Members may be concerned about the impact on passengers, so let me reassure them: none of this will limit people’s ability to fly. We expect minimal changes to fares, with an average ticket increasing or decreasing by up to £1.50 a year. I am pleased to say that this is a product of many months of consultation with the industry. Airlines are calling for it, airports are calling for it, SAF producers are calling for it, environmental organisations are calling for it, and the Government are therefore getting on with delivering it.

I am sure that we wish the Government well in what they are trying to do. I gather that the International Air Transport Association highlighted only last week that, at the moment, sustainable aviation fuels cost approximately five times as much as conventional jet fuel. Will she explain how the measures in the Bill will bridge that gap to make it economical?

[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.
