Yes, and I've laid them out quite clearly, for example, in The Morning After. I believe you only need four or five policies. The policies I've seen so far seem wrong-headed to me. On the public transit subsidy, we're just simulating that right now. I may come out with something from the C.D. Howe Institute, but our guess is that it will have very little effect on people's use of transit. It will effectively be a transfer payment to people who already buy transit passes; therefore, its cost per tonne reduced would be exorbitant, at $500 or $1,000.
Likewise with ethanol content. If you don't put in the other policies that I'm talking about to constrain people's use of the atmosphere, it could very well be that the refiners that are built to help make ethanol would burn coal or whatever was the cheapest fuel available, as we've seen in the United States. We're also doing a simulation for the C.D. Howe Institute that we will probably come out with at some point, and it will show again a negative effect of that kind of policy.
Unless you're interested in moving very quickly on a strong message about use of the atmosphere in the way I've talked about, I don't think your policies will work.
