Well, definitely, because in fact the 15 member states—now we have 27—do hang together very intensively within a common economic market. So environmentally speaking, we can learn from each other. Economically speaking, within such an integrated economic market we have to minimize economic distortions. Otherwise, member states are blocking each other. They are sitting on the fence and seeing what the others are going to do.
As part of our emissions trading scheme, we have to agree on national allocation plans. The commission has been developing a common methodology to make sure that industry, the power sector, and energy-intensive industry is treated in a very comparable way in the different member states. I'm absolutely sure that without such a common approach, it would have been extremely difficult for every single member state, on its own, to reach the targets in a cost-effective manner.
Our experience to date I think has been helpful, and emissions trading has facilitated that a lot.
Thank you.
