We feel that it's important to maintain the signal for emissions reductions so that we continue to make progress toward full decarbonization. There are no tools that we can leave on the table. We don't have a clear proposal at this point, although what I would say is that there have been claims that the price would increase to amounts that look like $300. This is far from what we are suggesting or thinking about when we're talking about a price increase beyond 2022.
This number that has been raised is the price of carbon should we not have any other measures in place to reduce emissions. This is not what the pan-Canadian framework on clean growth and climate change proposes. I think that for the certainty of investors, a schedule of increase that just stays the same, a $10 per tonne increase annually, is a reasonable proposal.
