The reality is that yes, as Nancy said, many of our businesses facing regulation would like to see the flexibility of some kind of an emissions trading regime. The reality is, though, that one can't answer that question without understanding what the targets are and how they relate to what's realistic and achievable for those industries. Otherwise, the previous schemes we've seen would largely--and the government has acknowledged this--mean that all major industrial emitters in Canada would be buyers. That's really a tax, not an emissions trading regime.
