That's a great question. I don't want to say that renewable natural gas isn't a climate solution. It absolutely is a climate solution. I just don't know if it is the climate solution.
As I said, I just don't know if we have the volumes in Canada to get to a significant, mandated requirement. Certainly, the costs would be very significant. There is an issue about whether or not the renewable natural gas will have the same physical and chemical properties as the virgin product from a feedstock perspective. There should be more study in this area. To say that we need a mandate in this area.... I think there just isn't enough fuel in the market right now to create such a mandate.
