I can see the Whip looking at me with some care so I will be very quick. First, we have a moral duty because much of the climate change that is happening at the moment has actually been caused by us because we were the first in the Industrial Revolution. Secondly, if we want other, much less well-off people to follow, we have to set an example. Thirdly, 11% of the emissions in the world are made by organisations that are headquartered or sold on the London Stock Exchange, so we must realise how big our reach is.
Fourthly, because we have led the world—although we do not now—other countries are now doing significantly more than we are. The President of South Korea is here on a visit today. He comes from a country that has a programme of very considerable remit which will end up with it being carbon-neutral by 2050. China is moving from a carbon-intensity target towards a carbon-reduction target for the mid-2020s. It has already been shown that by leading the world, the world is changing. But if we stand aside and say, “After you, Claude”, nothing will actually happen. That is why we have to do it. We do it for the poor. To use the poor as an argument against doing things on climate change seems close—although I am not saying this about my noble friend—to reprehensible.
