My Lords, the order was laid in draft before this House on 24 July 2024. It will ensure that sustainable aviation fuel, also known as SAF—I hope that your Lordships will tolerate the use of that acronym—makes up an increasing proportion of the jet fuel supplied to the UK each year. As a consequence, the greenhouse gas impact of flying will be significantly reduced. The draft order, referred to as the SAF mandate, will contribute to fulfilling our manifesto commitment to secure the UK aviation industry’s long-term future and it has received significant cross-party parliamentary support to this point. No issues were raised on the draft order at the Secondary Legislation Scrutiny Committee or the Statutory Instruments Joint Committee.
The SAF mandate is a bespoke mechanism for guaranteeing demand for SAF in the UK. It will send a strong signal to industry that SAF will play a pivotal role in the future of UK aviation and will provide an incentive for SAF to be supplied. However, it is just one pillar of a wider approach to capitalise on the environmental and economic opportunities that SAF offers. The UK will also lay legislation to support SAF production in the UK by providing revenue certainty. This will strengthen the UK’s leadership in SAF production, improving its fuel security while fostering industrial development and generating green jobs.
We are pleased to see SAF starting to be brought to the UK market in small but increasing volumes. The SAF mandate will help to address barriers to widespread adoption and realise the full potential of this technology. The United Kingdom has a rich history of being at the forefront of aviation innovation and we will continue to show leadership by introducing one the world’s most ambitious frameworks to drive demand for SAF.
SAF is blended with conventional kerosene to be used in existing aircraft and engines without modification. It is a low-carbon fuel that uses sustainable feedstocks instead of crude oil, which achieves greenhouse gas savings across its lifecycle production and use. It can be derived from a wide range of sources that achieve carbon savings relative to fossil fuel in different ways. They include biomass derived from wastes and residues; fossil wastes that cannot be avoided, reused or recycled; and renewable and nuclear energy. This means that we can draw on resources that would otherwise be discarded, such as agricultural residues and black binbag waste, to make jet fuel. The existing renewable transport fuel obligation, or RTFO, rewards the supply of SAF but does not obligate aviation fuel supply. By introducing a specific obligation on aviation fuel, we will guarantee a minimum supply of SAF.
I turn to the specific content of the statutory instrument. It introduces two obligations on suppliers of fossil jet fuel: a main obligation and a power-to-liquid obligation. The obligations are placed on jet fuel suppliers at the point at which their fuel can be supplied only to UK aviation. Each obligation period is one year in length and runs on a calendar year basis. To fulfil the obligations, suppliers must redeem SAF certificates at the end of the obligation period. Certificates are awarded to suppliers of SAF that meets the sustainability criteria. The number of certificates that a supplier receives is in proportion to the greenhouse gas savings that it achieves.
Power-to-liquid fuel, a type of SAF made from carbon dioxide and renewable or nuclear power and heat, will be rewarded with specific certificates that can be used to meet the power-to-liquid obligation. This will specifically incentivise the supply of these fuels, given their potential for higher greenhouse gas emissions reduction and lower risk of environmental impacts.
SAF made from segregated oil and fats, such as used cooking oil, commonly called HEFA, will also receive separate certificates. Suppliers can use these certificates to meet their main obligation, but the amount will be capped, starting from 2027, to allow market space for novel technologies. All other types of SAF are rewarded with standard certificates, which can be used to meet the main obligation. All certificates can be traded between account holders for a price determined by the market. The value of these certificates therefore provides a revenue stream for producers of renewable fuels and demand for their products in the fuel market.
Where a supplier has a shortfall in certificates to meet the obligations, a supplier must pay the buyout, which is a fixed price per unit of energy. The purpose of a buyout mechanism is to provide a way for suppliers to discharge their mandate obligation in cases where they are unable to secure a supply of SAF, preventing excessive costs from being passed on to consumers. This price is set to be higher than the expected cost of producing and supplying the same unit of SAF under normal market conditions, thus incentivising the supply of SAF.
The instrument also sets out the criteria that SAF must meet in order to be eligible, to ensure that we maintain the highest sustainability credentials. The order makes provision for the administration and management of accounts for suppliers to ensure that a record is kept of obligations and certificates. It also sets out appropriate processes for the revocation of certificates and issuing penalties where certain provisions are contravened.
Renewable fuels already contribute one-third of transport’s emission reductions from the current carbon budget. However, this is almost exclusively in the road fuel sector. Introducing the SAF mandate will broaden the use of low-carbon fuels into aviation and secure the long-term future of this transport mode. It is projected that, between 2025 and 2040, the SAF mandate could deliver up to 25 million tonnes of SAF, securing a saving of up to 54 million tonnes of carbon dioxide.
To conclude, we must act now to address the global challenge of climate change. Historically, the aviation industry has faced difficulty in achieving carbon reductions. However, SAF represents an immediate opportunity to change this. The technology has been proven to achieve significant greenhouse gas savings and it can be used in aircraft today.
