I agree with the end of the hon. Lady’s point. My proposal is deliberately pragmatic. It would put zero emissions into law, but the date would be decided by Government on the basis of advice from the Committee on Climate Change. That is right and it would be the lowest-cost way of proceeding. We need the experts’ advice. After all, they were appointed with cross-party support.
I am delighted to say that since I made this proposal three months ago I have had constructive discussions with the Government. I will not try to predict the reaction of the Minister of State, but I want to record my thanks to her, the Secretary of State, and the Minister for the Cabinet Office for their willingness to engage. I hope that we can move the idea forward in the months ahead and demonstrate once again the cross-party commitment to tackling climate change that is shared by the vast majority of hon. Members. I look forward to the Minister’s response.
