On carbon capture and storage, the demonstrations, such as they are right now, are early days. It's an early investment. The IEA expects that by 2050 CCS could account for a reduction of 20% of the reduction required in global GHG emissions. In Canada and Alberta, it could be much greater than that. Investment by the government is in very early-day demonstrations of that type of technology to see what the barriers are from a technology perspective while working with provinces as well. The provinces are looking at their regulatory framework. That's how they adopt that type of technology.
Again, this would be a policy question. We're working on the demonstration side, trying to make sure that this is a technology that will work as it gets deployed on a much broader scale.
