A very significant portion of our spending on energy research and development would be for projects with an environmental dimension to them. I would have to go back to see if we could extract hard numbers on that, but reducing the environmental footprint is a very important dimension of the research and development.
I would also add that a lot of the work we do is on energy efficiency, which certainly helps reduce emissions and other environmental impacts. It also makes us more competitive and prosperous as a country. It makes us more secure, both as a country and a continent. A lot of work has payoff for more than one objective, so if we were to allocate by objective it would probably come to more than 100%, if you can see my point.
Oil sands production today is much less energy-intensive than it was ten years ago. Huge progress has been made, including work directly done by the centre in Devon. Perhaps it's a case of the glass half full or the glass half empty. There has been huge progress in this area.
