I don't think we have anybody from international here, so I'll address the question.
I take it the question was primarily focused on international climate change activities. We have a range of international climate change activities. We are active participants in the United Nations Framework Convention on Climate Change, which is a forum for all countries to come together and basically exhort and create a framework for collective action and individual action. It also does important work on developing rules around such things as tradable emissions permits across countries.
