Certainly. Again, that is possibly a question that would lead to a Ph.D. thesis. There are quite a few areas that we can talk about.
The first thing that I would say is that we're very happy to see the change in direction by the federal government on the clean fuel standard. When it was originally conceived, it was designed to also apply to industrial fuels. That would have been incredibly complicated, and it would have exposed the industrial sectors in Canada to a significant amount of external trade competition as a result of the increases in costs there.
Another issue that's come up is the prospect of renewable natural gas. Quite frankly, there just isn't a lot of evidence right now that some type of increase in renewable natural gas content in Canada is something that we could either, first, achieve or, second, consider economically. Renewable natural gas, depending on the source, can be up to four times as expensive as virgin natural gas. The other issue is just how much of it we have, and we don't have all that much.
To see the moves that the government made on the clean fuel standard for industrial fuels.... That was a very good idea. The reason is that the output-based pricing system has mechanisms in it to account for competitiveness issues outside of our border.
