My Lords, I thank the Minister in particular for acknowledging the importance of understanding how we can set targets. It is very easy to accept the case for saying that GDP or some other measure should not be mentioned, but we live in a world where international agreements have to be made using consistent units. The OECD or the UN is not the place to argue that we can suddenly revisit the national income accounting methods created by John Maynard Keynes and others in Cambridge in, I think, 1944-45. There has to be some international agreement about how you measure the economy.
Some people say, “Let us measure the value of forests”, and I have very great sympathy with that, or the destruction of habitats and the elimination of species—the lion, the tiger and so on. We need a practical way to see how far—and this leads up to the Glasgow debate—there can be any agreed view around the world on how we break the link that we all know exists between economic growth and emissions, which are becoming a very dangerous trend in relation to extreme temperatures, to mention only one point.
In light what the Minister has said, there should be something more specific for people in the next few years. It has not been mentioned but it is important that the people of the country as a whole understand the answer to a widely stated nostrum that we cannot do anything about climate change or we will get poorer. We have to have a narrative, with the Government behind it, so that we can actually do something about it. Changing the coefficient is a technical way of saying it, but we must get to a position where the people of this country can ask, “How are we doing on this?” and the answer is that we are doing something here and now and helping it to become part of the standard world metric. However, I beg leave to withdraw the amendment.
