Lord Ravensdale (CB)

My Lords, as the noble Lord, Lord Moylan, referred to earlier, I think this wraps up a number of points in previous groups. It is a good point at which to have this debate about what actually qualifies for support under the revenue certainty mechanism. First, I take the opportunity to congratulate the noble Earl, Lord Russell, and the noble Lord, Lord Addington, on their peerages. It is absolutely brilliant news, and I am really pleased for them. There are two parts to this amendment, and I would like to deal with them in reverse order. At Second Reading, I asked a question on the eligibility of nuclear energy or nuclear-derived SAF. The Minister said: “SAF produced using nuclear energy is and will be eligible for the SAF mandate”.—[Official Report, 20/11/25; col. 990.] I noted that he said the SAF mandate and not the revenue certainty mechanism. What I am really after from the Minister is explicit clarity that nuclear-derived fuels are within the scope of the revenue certainty mechanism, and perhaps some commentary on how this flows through the legislation. The reason for needing this clarity is that the legislative route is a little convoluted. Clause 16 defines sustainable aviation fuel as “aviation fuel that is renewable transport fuel”. Renewable transport fuel is defined in the same clause as “anything that is (or is treated as) renewable transport fuel for the purposes of Chapter 5 of Part 2 of the Energy Act 2004”. As I said at Second Reading, I proposed the amendment to the Energy Act 2023 that led to the insertion of Section 131D into the Energy Act 2004, which treats recycled carbon fuels and nuclear-derived fuels as renewable transport fuels. But it was stated there that it required secondary legislation to take effect and to treat these fuels as renewable transport fuels. I noted that this has been done for recycled carbon fuels, but the secondary legislation has not been done for nuclear-derived fuels. We have this quite convoluted route through the 2004 Act, the 2023 Act, the secondary legislation and the SAF mandate, so I would appreciate that clarity from the Minister on nuclear-derived fuels. That is the second part of my amendment to ensure that they would be within the scope of the Bill. My second point is around the eligibility for this Bill of certain types of sustainable aviation fuel. I am seeking to exclude first-generation SAFs from the revenue certainty mechanism. I do not see the need for crop-based biofuels to be given support, because the production pathways for these fuels are already there—they are already commercialised at scale. On previous groups we have talked a lot about some of the issues with crop-based biofuels: they are CO₂ saving; they compete with food, potentially raising food prices; they drive land use change and reduce biodiversity. Those fuels have all those other effects, and they are already commercially viable and commercialised, so I cannot see why we need them to be within the scope of the revenue certainty mechanism. That is brought out in a lot of the government guidance as well. The driver behind the Bill is to provide a mechanism for second and third-generation sustainable aviation fuels. That has been stated repeatedly by the Government. I cannot see a good reason for including these fuels within the revenue certainty mechanism. I look forward to the Minister’s thoughts around that. I beg to move.
