I think it's very important. This is one of the ways to send appropriate market signals to investors. Of course, if there are investment opportunities here where there's a return and that can be traded on the market, then yes, I think it's extremely important.
But to reiterate the point that Monsieur Bertrand has made, we need a well-defined market first of all. You don't have a market unless it's defined and regulated. Number two, the extent to which it can be international and efficient is extremely important.
But if you were going to have a perfectly competitive market with zero administrative costs involved--and I would hope we would all try to reduce the administrative cost to participating--the price over a period of time would equal the marginal cost of new technology around the world required to reduce emissions.
So what you would see, first of all, are investments in those opportunities worldwide where investors could see the biggest return for the lowest-cost investment. That would probably be in emission reduction technologies, perhaps in developing countries. But the oil sands industry, any industry in Canada, would have to be competing internationally for that investment.
Much of the technology that would be required in the oil sands or in other industries is considerably higher than $15 a tonne for making those investments. So the oil sands industry or any other industry in Canada would have to compete for that international investment.
But it's a useful mechanism, and clearly, one of the weaknesses of our approach to climate change is that we have not had a very clearly defined registry or a very clearly defined market. Our organization has been involved with Chile, with Brazil, with China in identifying projects where we can transfer manufacturing technology to reduce emissions, and one of the biggest problems is that we don't have a Canadian registry in order to book those initiatives and there's no way of monetizing that here, so the progress that is being made is simply not recognized.
