We have not costed doing nothing. We have tried to estimate the impact of climate change on the Canadian economy in two scenarios. One is stated policies, under which everybody across the world does what they've promised to do and does it on time. Another scenario is that countries do what they have done so far and nothing more. We find that the impact on the economy is—no surprise—greater in the scenario in which we do what's currently implemented and nothing more. That estimate has big caveats, because it's one of the first attempts at estimating the cost of climate change. It does not factor in potential tipping points where exceptional climate events would become even more frequent, and the cost of these exceptional events.
It's very much a first attempt at costing climate change. It has numbers, but again, it's still something that is in its infancy.
