I have a chart that was handed around that in fact does that. It's a little bit complex, because we're looking at a variety of technologies, and it's how you package them together.
I will say this to start. First, if we're going to see a program, for us a prompt launch is more important than the duration of the program. We've got a very definitive date coming up with the 2010 model-year engines, and we would want to avoid a pre-buy situation in 2009. The paper I gave you suggests that it depends on what percentage the federal government was prepared to invest. For example, for a simple package that would have the smog-free truck plus two or three of the fuel efficiency measures, we're looking at a Government of Canada investment at, say, 15% of about $56 million, compared to an industry investment of $320 million. I give some other examples at 20% and 100%.
Probably the best practical example is that initially there was a similar program for auxiliary power units in the trucking industry. These are electronic units that keep the engine running, as opposed to diesel. You use those to prevent idling and those sorts of things. There the federal government invested 17% of the cost, compared to the industry's 83%, and that was enormously successful.
As for us, we know that billions of dollars aren't going to drop from the sky. We have to replace our equipment at some point anyway, and we do have a vested interest in improving our fuel efficiency; what we're talking about is accelerating that investment. I think the government can do that with a rather modest investment that will see significant returns in terms of GHG reduction.
