Just on the point of whether there is a government you can look to that has done that sort of modelling and has the answer, I would point out that in the text box that we have in exhibit 1 on carbon pricing, we mention that the Government of British Columbia had committed to increasing its carbon tax to $50 a tonne by 2021. We don't talk about the greenhouse gases that will be reduced by that, but it may be that the B.C. government government has done that modelling.
