Well, Kyoto will be the important reference for fast-developing countries pushing under the argument of equity, and the argument of equity is fundamental. These countries tell us that in 150 years of industrial revolution, you created the problem, we didn't, so why should we now pay for your problem? That's called Kyoto.
When you look at the facts and the projections of emissions in the next 20 years, concentrations of carbon dioxide and carbon dioxide equivalent will peak at more than what is souhaitable, and then we'll have to come to stabilization at 450 parts per million. It's going to take everybody's cooperation to get there, and we're at the very beginning, parodoxically, of this process. When you look at the curves and at the difference between the demand and the offer of liquid fuels, you see that's going to be conducive to going to coal. You can see the numbers in the next 20 years. It's frightening.
We have to be credible, but also we all have to be there, and we have to take the means to get there together.
