My Lords, it is obvious that in the international system there is a bit of a crisis in knowing how to take the world consensus forward. We are looking forward to Britain making an active contribution leading up to Glasgow. I say this because the international system has at some point got to agree specific concrete parameters so that we do not have an endless debate about China, India, Indonesia, Russia or Brazil, as it were, not playing by the same rules as other people. There has to be an understanding, which I think is to be supported, and an acknowledgement that the third world will have different rules from the second and first world. You can imagine the difficulty of agreeing internationally how to define those ideas.
I have great sympathy with the Government for trying to put together a leadership role for the meeting in a month or so in Glasgow, but this is very relevant to what is in this amendment. In practice, it is narrowing down to the question of how we in this country decide how to set targets for greenhouse gas emissions. One very important way of doing it is to define those targets or metrics in relation to the growth of national income. Everybody knows that there is some connection between the growth of national income and the growth of greenhouse gases. If people say that it is not possible to have a reduction in greenhouse gases without doing something to reduce the growth of national income, I say that the fact is that one can do that. We are doing it in this country already, partly because of the accelerated reduction in emissions arising from the use of coal to generate electricity.
We have to come to some conclusions about what exactly it is that we are concretely proposing. In this amendment, we have an idea that a 1% increase in the national income should be associated with a 1% reduction in emissions of greenhouse gases. That is a very crude example, but it is impossible to make progress on the short-term link to the long-term aspiration of zero emissions without trying to find some way in which people can go forward—ideally with international agreement—on how we are going to change this coefficient. That is what is in this amendment.
I am very pleased to have had the chance of an initial talk with the Minister of State last week about how these propositions can be taken forward. I look forward to hearing what he has to say. I am encouraged that some constructive thinking is emerging from the proposition in this amendment.
This also means that there has to be quite a big change in how Whitehall and government generally set targets. We do not have short-term targets at the moment. We have excellent reports from the Committee on Climate Change and associated budget work, but we have reached the point where we have to bite the bullet and look seriously at trying to acknowledge that we have to reduce the coefficient around the world,
where climate change is a risk because carbon and greenhouse gas emissions are growing at greater speed than national income. We have to reverse that.
I hope the Minister will accept that work should be taken forward on the idea of these metrics to reduce that coefficient and give a positive response to the principle involved. I look forward to his response. I beg to move.
