We consider the recommendation that we've put forward today to be very much a minimum start in terms of what has to happen to get us on the track we need to get on to, to avoid dangerous climate change impacts around the world. That includes a price on carbon, either through a tax or a trading scheme of no less than $30 by 2009 and no less than $50 by 2020. That would really be considered very much a minimum. We need to package that with other policies, regulations, and standards so that we shift the path we're on that will not get us to where we need to be to avoid the impacts of dangerous climate change.
