On this one I'll let my colleague Ms. Leach go into detail.
I think one of the things we did note was that in the plan of 2010 there was $1.5 billion transferred to the provinces. But as yet there isn't a system in place, and I think this is a big challenge. This is not simple or it would be there. But it's important to have a system in place where provincial reductions, federal reductions, and private sector reductions are all able to be rolled up into a comprehensive national single number.
I think, particularly in the private sector, there's a lot of work now under way in certification of greenhouse gas reductions. We noted in the chapter that right now Environment Canada and other officials are working on a system with the provinces to be able to count that up, but as of this moment it's not able to do so.
