Climate Change Bill [HL]

I thank the noble Lord for that intervention and I agree with much of what he says. I am not fully resolved on the mechanism myself. All that exists at the minute is part of the remit of the climate change committee, which says that this will be something on which it advises. I would certainly require there to be a restriction even if we decided later what it was. I believe we should make up our mind on that restriction before the Bill gets Royal Assent. This is a core area. It does not get in the way of carbon trading happening within the schemes that exist at the moment or those that will exist in the future. In terms of the UK’s leadership, and the Government’s and the Secretary of State’s desire to lead, a formula like this is essential.
