Keep in mind that the companies are always trying to do things better. Most of the emissions come from burning energy, which is needed to produce the oil and gas. You can save money by improving your efficiency, so that kind of stuff is going on all the time.
On the production side, a lot of the R and D happens in the service companies on the drilling techniques and that sort of thing, so it's not very clear exactly what that is because it's spread out. We rely on technologies developed elsewhere in the world.
While it's not a Canadian company, Exxon Mobil just sank $700 million to $900 million into developing liquid fuels from algae, so that kind of basic R and D is going on. But I'm afraid I don't know how much is actually happening from the Canadian companies.
