I draw your attention to the Lieberman-Warner act in the United States. It's a bipartisan piece of legislation that has already essentially set the framework for a cap and trade system in the United States. That bill won't pass per se, but that set of rules will be in place when the next U.S. administration comes in. When that happens we will have to follow suit.
It is important to get a handle on this carbon issue, because if we look five years down the road, we could well see carbon tariffs being put up by the United States, especially on places like China and India. We want to make sure we're on the right side of that--not in front of it but behind it.
