I think targets have an important value as you approach a meeting like this, and in fact to some extent Copenhagen can be deemed a success already, in that it has stimulated a great deal of discussion among other countries as to what their targets should be. I have a document that talks about the pledges. I can make it available to the clerk. It was done about two months ago and lays out the different targets. But you know, in the last week we've heard a target come up by Korea, by Brazil. Russia has changed its target. So it has stimulated a lot of discussion within many governments.
That being said, a target without domestic legislation to go along with it is relatively meaningless, as we've seen from experience. So I think to have credibility it has ultimately to be backed up by some legal form in individual countries.
