The policy commitment is to achieve an absolute reduction in emissions by 2020. In absolute terms, our emissions in 2006 were 718 million tonnes. That would mean, in 2020, our annual emissions would be 575 million tonnes.
On the specifics of the industrial regulatory regime, I think Mr. Prentice spoke about that recently in the House in terms that ongoing work. I wouldn't wish to comment further on what he has said.
The overall policy requirement to fulfill the commitment is to have in place policies and measures that achieve an absolute emissions reduction. The choices to be made on that, of course, are still under discussion as it relates to the industrial regulatory regime.
