There are two parts to this. One is the way you operate your business, and we have seen dramatic changes, particularly at the provincial level, on things like flaring and venting the gases that are released. We're looking forward to the government's upcoming air quality and climate change package, because clearly that's going to push things a little further, and we will participate in it.
Quite honestly, Ms. Ablonczy, the biggest issue is capital stock turnover. When you bring in and build an $8 billion facility, which is what a new oil sands project costs, you're not going to turn around and change out the equipment in two years. Changing out equipment and the processes that go with that take time, both in terms of development and in terms of deployment.
To throw out one statistic, the new oil sands plant will have 99.5% SO2 recovery. If you go back to a plant built 15 years ago, it's probably less than 80%. On the other hand, you don't retrofit a facility quickly, so we support capital cost allowances and those kinds of things, and we think they are important. It's clearly something we spend a lot of time on, and we will, I imagine, continue to do so.
