I don't mean to cut you off, but I think I want to narrow down your answer a bit. I believe Professor Leach said in his opening statement that a barrel of oil had never been as emissions-intensive as it is today. The emissions intensity of a barrel of oil is rising, not declining.
It feels as though you're trying to convince us that it is possible to produce oil with a lower carbon footprint. Personally, I think it's impossible to do in a cost-effective way. As soon as you try to lower the emissions intensity of oil, you automatically have to invest in R and D. In light of that, I want to know whether your sector is cost-effective or not. If it can't be done without the financial support of the government, we have a real problem.
I'd like a clear answer to that, please.
