The two questions are these: first, can it; and second, should we do it?
We just went through the numbers, and as Matthew Bramley said, the amount of credits available when I drop hot air out is 1.2 billion to 1.5 billion in total over the five-year budget period. So if I take 1.5 and divide it by 5, that means 300 million a year. So when you're positing that we might go out and buy 135 million tonnes, you're positing that Canada can secure the lion's share of the total supply out there, and I can't see a way to do that. So 135 million tonnes is higher than I think is conceivably possible, if we wanted to do it. That's the first thing.
The second thing is that in that supply that's out there, which I just gave you the numbers on, the real difficult part is that, in my view, last year the CDM/JI board made a very critical mistake in decision-making in that they agreed to issue credits to developing nation manufacturers who make HCFC-22. It's a refrigerant that, after CFCs, is the most potent ozone-depleting substance and it is a highly potent greenhouse gas. So when you make HCFC-22 and sell it, you are discharging an ozone-depleting substance and greenhouse gas into the environment.
It is illegal to make HCFC-22 in Canada. As of January 1, 2010, under existing law it will be illegal for us to import it, because we consider it a most damaging substance. To date, 51% of all of the credits that the CDM/JI board has approved are credits that are being issued to those plants. The U.S. EPA estimates that the effect of that one decision to issue credits to those plants completely wipes out all of the benefits of the Montreal Protocol by 2020 and adds 3 billion tonnes of greenhouse gases to the upper atmosphere that would not have been emitted in the absence of that decision.
Before that decision, the average HCFC-22 manufacturer made a before-tax profit of $500 U.S. a tonne. After that decision, his before-tax profit jumped to $2,600. There's nothing you can manufacture in the world more profitably because of that one decision.
So when I'm saying we're going to go out there and pick up 91 million tonnes, I'm saying we're going to go pick up 91 million tonnes and 50% of them are going to be us giving money to plants that are making a product we have already deemed so dangerous it's illegal to make or import into Canada.
