Lots of people have concepts. All sorts of people in downtown Calgary have their own models. I don't know very well. I think it really depends on the details of the government's plans.
I'm sorry to dodge that question. My amount of uncertainty would be pretty big.
I'll say this. If you really wanted to reduce emissions to bring them back down to current emission levels in five years, which I believe is what the government said they would do, if I recall correctly, I think the sorts of carbon prices necessary to achieve that would be very high, over $100 a tonne of carbon, $100 a tonne of CO2, that kind of number.
