I think you touch on a very good point, in terms of what needs to happen in terms of the context to actually make some of these what we refer to as step-wise changes occur. What we have seen--and to give the industry credit where credit is due--are some incremental improvements on an intensity basis, whether it's the amount of water used per barrel of synthetic crude oil or the greenhouse gas emissions, etc. But with the pace of development and the rate at which these companies are expanding, despite those intensity improvements on all fronts, we're seeing a drastic increase in the environmental footprint. So it begs the question, how do we manage that overall cumulative growth of environmental impacts?
Certainly one of the challenges I alluded to is that we don't actually have the regulatory framework in place today to actually drive the changes we need within the industry. I think government has a very clear role on the regulatory side, as well as in terms of using things like its fiscal tools, like tax concessions, such as the ACCA, to be directed very specifically at investments in technology that will make a very significant step-wise improvement, whether it's reducing greenhouse emissions or improving water use.
