You're right. It is very difficult, in a package of 80 different measures, to attribute specific megatonnes to individual measures, although we know that carbon pricing is a significant contributor to the expected reductions. I think the commissioner's report agrees with that statement.
I think we're probably in a world where we could say, with some rough analysis, that up to one-third, potentially, of the emissions reductions that we're projecting to 2030 would come from carbon pricing.
