Climate Change Bill [HL]

My Lords, I, too, support my noble friend. If the Prime Minister is not responsible for this task, it is not at all clear that the Secretary of State for the Environment, or whatever the department will be called at the time, necessarily should be, quite apart from the very powerful points made by the noble Baroness and the noble Lord, Lord May. It is obvious that climate change involves the Chancellor of the Exchequer. Potentially huge costs are involved in anything to do with climate change, and they concern the Secretary of State for Transport, or whatever that department will be called at the time, and various other departments as well. It is not clear that the Secretary of State at Defra is the natural leader; because of the financial implications, it could just as easily be the Chancellor of the Exchequer. Therefore, the Government should seriously consider the point about the Prime Minister, not only because he is the ultimate spokesman for the Government and ultimately responsible for their policy but because this is not an issue that falls naturally into any one department. It crosses departments to a much greater degree than almost any other issue that is likely to come before Parliament.
