"It will stop economic growth." That, as the Minister for Climate Change said, is the biggest fallacy. If we look at countries that have achieved reductions in carbon, they are the countries with the highest growth. They have harnessed technology and they have managed to do this in growing economies. And whilst Treasury projections in respect of this bill see a modest reduction in GDP, in fact history would suggest that this will be a huge boost as we enhance our productivity, enhance our energy efficiency, enhance our transport networks, and so on. So this is, in fact, a great and timely piece of legislation. It is a big bill, and, as was noted, it's a complicated bill.
