My Lords, I will not detain the House for very long, bearing in mind the late hour. I thank all noble Lords who have taken part in the debate; we have had some fantastic contributions covering a wide variety of topics. I thank the Minister for his wide-ranging responses to the points raised. I also join others in congratulating the noble Earl, Lord Russell, on his truly excellent maiden speech. I look forward to many future contributions from him on matters to do with the environment and, no doubt, other topics of importance.

I also acknowledge the noble Lord, Lord Deben. I had the honour of serving on the Climate Change Committee under his chairmanship for a number of years. I do not know which of us was more alarmed when we found that on many occasions, perhaps even on most occasions, we tended to agree with each other—but we were always on the right side when we agreed. I acknowledge his tremendous contribution to the Climate Change Committee and the pleasure I had in serving under his chairmanship.

I just want to very briefly refer to three points mentioned in the debate. One—which I think many noble Lords including the Minister effectively responded to—is this notion that it is either mitigation or adaptation. I am sorry to say that the noble Lords, Lord Frost and Lord Lucas, seemed to feel that you could do one but not the other, and that is clearly not the case. They are both needed.

The second point again has been dealt with by a number of speakers, including the noble Lords, Lord Deben and Lord Teverson: the deaths from cold and heat. It is a peculiar kind of levelling-up argument to say, “More people are dying from cold. Therefore, we can allow the heat deaths to go up”. Perhaps one way of emphasising the bizarreness of that assertion is if you consider that last year 1,675 people died as a result of being killed on our roads. Compare that with the 86,000 deaths that arose as a result of bad diets in this country, according to the Global Burden of Disease study. Does that mean we should allow road deaths to increase and not worry about them, maybe deregulating to allow people to drink and drive and drive too fast in speed-limited areas? Clearly not: we bear down on all causes of death because every death, as the noble Lord, Lord Deben, said, is a tragedy for the families whose loved ones have gone away.

My very final point is about this figure of a cost of maybe 1% to 2% of GDP by 2050 for mitigation. When I was on the Climate Change Committee and it produced this figure, I almost asked, “Is it a big or a small number? How do we know?” One way of expressing it is this: if we reckon we ever get back to a trend of 2% growth per year in GDP, a cost of 1% by 2050 means we will delay until June 2050 being as rich as we would have been in January 2050—a tragedy for all of us: six months of being that bit poorer. When we throw out numbers as a percentage of GDP, we have to be careful about what they actually mean.

Having said that, I reiterate my thanks and wish all noble Lords, as others have done, a very relaxing and pleasant summer break.

Motion agreed.

House adjourned at 9.45 pm.
