I'll answer on behalf of ICON.
Most of the companies involved in the oil sands have been active in terms of emission reductions on a voluntary basis. A lot of them have signed on to the Canadian Association of Petroleum Producers' voluntary program that was run by NRCan, and have been and probably still continue to either make reductions or make plans for reductions. Some of the companies have made significant emission reductions in their operations since they started on that program in 1997.
When we talk about a project on the scale of the ICON project—a 20-megatonne carbon dioxide pipeline—we're talking about an infrastructure, a system that surpasses the ability of a single project, or perhaps even of a group of projects and companies, to bring all of that together. We are looking at appropriate ways for that risk to be shared amongst the participants, both the federal and provincial government. I would note that the creator of the wedge concept, which the national round table used in part of their analysis, was a Harvard professor named Dr. Sokolow, and he did indicate with respect to carbon capture and storage that subsidies may be applied at the early stages to get over the initial economic hurdles.
On regulations and controls, we've understood for a number of years now that regulations will be forthcoming in this area. We anticipated those when Kyoto was signed. We've been looking for the regulatory process to be refined and defined in Canada, so that the investments we make are not stranded or otherwise disadvantaged in the future. We have seen some of that in the past, for companies that have taken early action, whether it was on a voluntary basis or not, and those actions have proved that they have not given or will not give the anticipated results. We would like not to see that happen in the future.
But we believe all three of those are going to be means by which we can effect real and verifiable long-term emission reductions in our sector.
