Lord Harper (Con)

My Lords, briefly, I support my noble friend Lord Moylan’s amendment. It is very important, particularly when we come on to later groups and are talking about the ultimate impact of this—which is that it will, in effect, fall on to the end consumer, as all taxes do—that we make sure that this is as simple and straightforward a process as possible, so that we can explain to people what we are doing, why we are doing it and what the cost is. That is always to be welcomed in policy-making. Further, this should be workable and straightforward for aviation fuel producers. They are the ones that we have chosen to put the mandate on, in giving them the legal responsibility to produce sustainable aviation fuel and blend it with their regular fuel. The current structure transfers the level of financial risk to them. I agree with my noble friend Lord Moylan, in that I suspect that behind this—the Minister can tell us that we are wrong if we are—is the Treasury wanting to make sure, not entirely unreasonably, that there is no risk to the taxpayer. However, in doing so, all that has happened is that the risk has been moved on to the fuel supplier. As my noble friend Lord Moylan says—I have thought about this as well, and I have listened to the industry—it seems that, for the producers to deal with the risk, they will have to increase what they charge the airlines. So rather than the cost and the risk falling on the Treasury and the taxpayer, it will, in effect, still fall on the taxpayer but just in their guise of an airline passenger who will face a higher ticket price. That is not very economically sensible. The industry is very clear that the Treasury should not be picking up the costs for this. The only sensible thing would be to have a per unit price. There would be some risk for the Treasury in the short term, but that could be smoothed out over time, and the Government are perfectly able to do that. That would be a much better solution, and I hope that the Minister can at least indicate that that is where the Government’s thinking is. If he cannot do that, I suggest that my noble friend Lord Moylan is correct that we should have done the detail before the legislation, rather than the other way around.
