One thing that hasn't changed a lot is that in Canada probably 70% or 80% of our spending is still on roads, not on public transit or rail, etc. So that's the wrong direction to go, as far as I'm concerned.
That's an old study from 1998, so there really isn't any new study that would give an estimate that if we are taking 41% of the people from automobiles, and we are looking at 16.4 million, what would be the greenhouse gas reduction per tonnage, that kind of thing? We wouldn't know that until the study is finished.
