Certainly. I'll start off by taking the opportunity to say that in 2007, 38 megatonnes of GHG came from the oil sands, and that was between 4% and 5% of the Canadian total. That was in response to a previous question.
On the economics and the current forecast, we have provided, in the slides--I think it was slide seven--a sense of where we think it's going.
There are two or three things to keep in mind when we're thinking about forecasts. First of all, to be candid, when you're talking to people in Calgary who are making these decisions, their views seem to change from week to week. It really is a moving target at the moment.
What we are confident about are two or three things. One is that there is a slowdown. There's no question that we think there's going to be less spending in the future than there has been in the past. How long that is, we don't know. If you look at the announcements that have been made by the major companies that have investments and that had announced major expansions, they're not saying they're not doing it; they're saying they're delaying it, and they're saying they're delaying it for up to 18 months, or for a certain period of time. You should know that with the environmental assessment for the construction phase, it takes six years, or in that range, to go from planning to application to approvals to construction. So it may be some time before we see some of these things come back and see significant growth in the oil sands. That's one point.
A second point I would make is that what we are seeing is a significant decrease now--and this is just recently--in input costs. I might have said, and probably should have said back when I was here in May or June, that the input costs for steel or engineering work, for labour, were.... “Overheated” is a word that was often used; that word is no longer being used. We are still seeing significant employment in the oil sands. We're not seeing production cuts, but we are seeing the input costs come down and come down significantly. Whether they will come down to where the price of oil is at is a challenge, and that will determine how much new investment there's going to be.
The final thing I would say is that whether it's a delay of two years or whether it's a delay of six years, if we look at the requirement for oil in the world and where it's going to come from, this will be a very important resource, whether it's, again, a decade from now or two decades from now. There is a view, even within the patch, that it's much more sustainable now in terms of the pace of growth and that there's an opportunity to work on some of the issues we're talking about today.
Those are some of the comments I would make. What we have provided to the committee is an early sense of what that growth pattern might look like. We're watching it very closely, and I think those three points are what I would say in terms of the growth forecast.
