It's not by way of a directive. For the time being, these are targets for the negotiations in Copenhagen. That's our position, and we will negotiate along these lines.
Later on, once we have an agreement--hopefully--it will be transposed into acquis, as we call it, in community legislation. Whether it's by directive or by regulation remains to be seen. We have the carbon market already. We've built on the Kyoto Protocol. In terms of implementation, there will be legally binding instruments internally.
