Sustainable Aviation Fuel Bill

The SNP welcomes the Bill, which will support the expanding use of sustainable aviation fuel. We view that as an important action among the range of actions that are needed to meet our legal and—most importantly —moral obligations to reduce carbon and support global efforts to tackle climate change.

My constituency has already played an important role in the use of SAF, with RAF Lossiemouth being the first Air Force base to use a SAF fuel blend for routine operations, for both the Poseidon submarine hunters and the Typhoon squadrons operating with a SAF mix. The RAF has also conducted demonstrator flights with 100% SAF-fuelled aircraft, and refuelled jets in the air with SAF. Indeed, Group Captain Sarah Brewin, the station commander at RAF Lossiemouth, has stated:

“The use of sustainable aviation fuel represents a significant milestone in the RAF’s journey towards helping mitigate against climate change. By integrating sustainable practices into our operations, we are not only enhancing our ability to protect the nation and deliver excellence on operations, but also contributing to a more sustainable future for generations to come.”

I welcome the fact that the RAF has some ambitious targets to reduce its aviation carbon emissions.

Inverness airport, publicly owned by Highlands and Islands Airports Ltd and responsible to the Scottish Government, has offered SAF to operators since 2023—a vital piece of work towards the Scottish Government’s deliberately ambitious goal of creating the world’s first net zero aviation region by 2040.

Offshore supply flights are one of the most promising parts of our aviation sector for SAF potential. With Scotland having the lion’s share of these flights from Aberdeen airport, it is vital that we see investment in SAF production in Scotland. Aberdeen airport, operated by AGS Airports, has supplied SAF since 2022, helping offshore industries to reduce their emissions. In 2021, one of the first fully-SAF helicopter flights in the UK took off from Aberdeen airport. BP is working with Bristow Helicopters to ensure that flights to BP platforms have used a SAF blend for more than two and a half years.

Scotland has an immense SAF production potential. The Bill alone is insufficient to see us reach that potential, but it is an important part of that. Scotland’s SAF progress has been held back by the inaction of successive UK Governments on funding the Scottish carbon capture, usage and storage cluster. The CCUS cluster is, in turn, integral to the investment in SAF production at Grangemouth.

Industry body Sustainable Aviation found that a UK SAF industry could deliver £2.9 billion annually to the UK economy, and create more than 20,000 jobs. It is vital that, with long-overdue funding finally confirmed today—something that the SNP has campaigned on for over a decade—the full detail is rapidly made clear and that pace is further injected into the process if that overdue cash is to be converted to construction and processing.

My SNP colleague and Transport Secretary in the Scottish Government has put in place an expert working group on sustainable aviation fuel to exploit the potential for the Scottish economy.

I have covered our broad welcome for the Bill, but there is one area that the Government must address, which is ensuring that feedstocks are coming from sustainable sources. We welcome the Secretary of State’s comments on further design work in the process and we will see that come through in the passage of the Bill. However, the Government must set out how they plan to manage the sourcing of sustainable aviation fuel feedstocks, so that the waste hierarchy is adhered to, and that existing businesses are not damaged by the introduction of the revenue certainty mechanism.

The most obvious illustration of this is the potential use of high-quality wood as one potential feedstock for SAF production. Some Members, but I suspect not all, will be aware that current demand for wood will outstrip supply by 2035. It will be obvious to everyone that it takes more than 10 years to grow a forest, so there is a real and well-articulated concern from organisations such as the Wood Panel Industry Federation and the many sawmill operators throughout the UK.

The UK wood panel industry currently supplies 65% of the UK’s demand for wood panel products, utilising 25% of the annual roundwood harvest basket and 25% of the annual waste wood basket. Fully 10% of the UK economy utilises wood panel products and, again, it will not be lost on the Government that, in order to achieve a 1.5 million new homes target—something the SNP welcomes, given our own substantial success in social and affordable housing build in Scotland—protecting and growing wood supply will be absolutely vital.

The eligibility criteria for the SAF mandate stipulates that feedstock materials must be waste that cannot be prevented, reused or recycled in accordance with the waste hierarchy. While the mandate acknowledges the waste hierarchy, which in principle would prioritise the use of waste wood for recycling before energy recovery, it is not clear how it will be monitored and enforced, leaving supplies of waste wood vulnerable to being used in SAF, against the eligibility criteria. There is a risk that the introduction of a revenue certainty mechanism will incentivise producers wishing to use this essential raw material for SAF production.

There will be time during the passage of the Bill for Ministers to mitigate this risk and address this issue across the Departments involved, of which there are several. I particularly hope that the Deputy Prime Minister’s responsibility for housing will help to focus ministerial and wider departmental minds on ensuring that the final iteration of the Bill supports sustainable SAF feedstocks. There are many good ways to manufacture SAF, and there are some bad ones. Let us get the mix right in this Bill.
