I don't know. I can get you that number before the end of this hearing. That will be a reduction relative to a baseline of 2005. That's how we established the target. The study we released last week indicated that pricing across Canada by 2022 will result in emission reductions of approximately 30 megatonnes. The federal government and the provinces have committed to collectively reviewing where we go with carbon pricing after 2022, so it's not possible beyond very broad generalities to predict what additional contribution carbon pricing might make between 2022 and 2030.
Again, it is a foundational measure designed to change behaviour, reduce emissions, and thereby make a contribution. It is not the exclusive method of attaining our target.
