We should never underestimate the ability of such people to play games. On the facts, we have said that as a condition of building any new coal-fired power station, at least 25 per cent. of the plant will have to be based on carbon capture and storage. There is a simple reason for that. Because it will cost significant amounts of money to build CCS plants, we think it right to demonstrate capacity at that scale. When the technology is commercially proven, which we hope will happen by 2020—that is the basis on which we are planning—plants will have to be 100 per cent. CCS-based. That is the most environmentally ambitious set of conditions for new coal-fired power stations of any country in the world.
