To get to your point, the credits are issued to the HCFC-22 manufacturers because they're combusting HFC-23, instead of discharging it to the atmosphere. So that's how the credit is derived, but that creates a subsidy for the manufacturer of HFC-22, which is the substance that is considered so damaging. I can write that up to explain it to you.
I went to the UN FCCC site this morning and went through the projects. If we said we're not going to buy freon tonnes, which I would recommend, and we place no other criteria on our purchasing—so we didn't look for Canadian content, we bought from the hog producers, who I'm not comfortable buying from—then, as of today, the maximum potential supply we could pick up on that market as far as I can tell is about 20 million tonnes, or 4 million tonnes a year.
So for us to get more than 5 million tonnes a year out of the marketplace, we'd have to get our little boots on and be working really, really hard to develop a bunch of new projects in the international marketplace. The supply that is not yet already attached to a European or Japanese progress report is not large right now.
