Climate Change Bill [HL]

My Lords, I feel as though I need to say this because the noble Lord has obviously cut the ground from under me, although I do not want it to be agreed that he has. While the Government are boasting about giving a lead by introducing the Bill unilaterally, without having had international negotiation—as long as one does not count the devolved Administrations—it does not mean that, when we go to the detail of the Bill, requiring international co-operation to get the right methodologies is not the right way to do it. We can be unilateral in giving the lead in introducing the Bill and the concept of the way in which we are trying to deal with climate change, but we need to operate with our international partners on the minutiae of the methodology.
