Okay.
Professor, I want to ask you another question.
We had the expert here this week, one of the top economists from the World Resources Institute, who said that this government's claim that its use of intensity targets would be connectable--or fungible, using the economic term--with the American absolute targets in a trading system would be impossible to achieve.
Can you help us understand whether we can connect an intensity-based set of targets with an absolute-based set?
