May I first congratulate the hon. Gentleman and his partner—I have looked at his Twitter feed—on the imminent birth of their second child later this year? I wish both he and his partner well. On his question, it was this Government who went to the independent Committee on Climate Change to ask for advice about how, and over what timeframe, to make that move to complete decarbonisation. We have only very recently received that advice. It will clearly need to be considered within Government, and we want to bring forward our decision at the earliest possible opportunity, because I share his view of the importance of getting on with this.
