Just to put that into context, though, in Buenos Aires in November 1998, the U.S. delegation said they would not ratify the Kyoto Protocol unless developing nations accepted caps. At that meeting, it was either Brazil or Argentina--I think it was Brazil--that proposed that key developing nations take on caps that were the equivalent of 40% above 1990 levels by the end of 2012, and China and India refused to buy into those caps. My understanding is their positions are not much changed today.
So the question is, how do we change their behaviour by saying what we will buy and what we won't buy, given that a 40% growth allocation is not acceptable?
