I will of course try to take as many interventions as I can, but I just want to respond to some of the points made in the debate.
After the very startling and worrying IPCC report, we were the first developed country to ask for advice on how we would achieve that target. We have asked how, by when and how much it is going to cost. We have to be pragmatic about this: we have to recognise the need for urgency, but we cannot bring forward policies and proposals that do not command the support of the people we represent. We can see just across the channel what happens when we do that.
