I can't answer that question. I would say, though, that what we should be aiming for is good policy here and expenditures that improve environmental performance and that improve our economy. That's long-term sustainable improvement.
Buying credits will do neither. It will neither help our economy nor help our environment. If we did all of that and at the end of 2012 we looked at our environmental performance and said, it's not very good, why is that? We spent all our money buying credits from somewhere else.
The objective in Canada should be to get the best possible environmental technologies and economic performance at the same time. I believe it can be accomplished. We've shown that it can be accomplished.
