Let me respond. I think I said earlier on--maybe I wasn't very clear--that we had reduced our energy consumption per barrel since 1990 by about 17%. Going forward, we would expect that in the foreseeable future we're going to see that virtually double, and we'll come down by another 17%. I believe there are probably other things we can do as we go forward. One of the things that has really been critical to the success of the oil sands industry is the whole issue of research and development and continuous improvement in everything we do. If you went back to the very early days, it cost over $30 a barrel to make a barrel of oil from the oil sands. We sure weren't going to grow this business if we hadn't had continuous improvement and figured out how to get those costs down. Part of getting the cost down was also getting the energy consumed in our business down as well. That's why we've been able to drive it down by this 17% that I'm talking about.
We've done it through a whole host of things. We've done it, as I mentioned earlier, by implementing new technology, mixing the oil sand with water, reducing the temperatures of those processes. We're not conveying the oil sand anymore; we're putting it through a pipeline. It's more energy efficient to transport it that way. We've gone from 170-tonne heavy-haul trucks to 400-tonne trucks. The fuel burned per tonne kilometre on those trucks is less than two-thirds what it used to be for the 170-tonne trucks.
So we have less fuel consumed in mining, we have less NOx emissions made, and we will continue to do that as we go into the future. So on a per-unit-of-production basis, we will continue to reduce energy consumed.
If you're talking about an absolute reduction, that means you don't grow the business. Absolute reduction would mean that we do not grow the business.
