Climate Change Bill [HL]

My Lords, before the noble Lord, Lord Taylor, replies, perhaps he will not mind if I ask the Minister to clarify something for me. I believe that we are drifting into an area of ambiguity that could trap us later. As I understand it—and I am very happy with it—the Minister said that matters which affect the behaviour of people in this country must remain issues of primary legislation and should not be devolved to decisions made by the climate change committee or to secondary legislation. Is that what he said?
