You need to look at this in two or three perspectives.
To start with, are companies reducing their intensity on an annual basis? Yes, they are. We have been able to see significant changes on that. That's number one.
Second, in the short term what do we see? We see continuing annual intensity improvement targets. We agreed with the previous government that we were prepared to live with those, and once the government brings its plans forward, we will continue to do that. So we will meet our obligations on that front.
When you look at the longer term, it comes down to two particular issues. One is, how do we manage carbon? This is a question of carbon capture and storage that affects not only us but manufacturers across the country, and the power industry in particular. Second, in the longer term, what are the energy sources that allow us to reduce those numbers you've talked about from a step change point of view?
In my discussion of my paper today, I talked about different types of technology. We have to have the nuclear discussion. A number of them are out there, so you have to look at this. Very short term, you have to start reducing the rate of growth. Medium term, we have to start managing it. Long term, we have to turn it down. But the technology is not there yet.
