Thank you for the question.
As I mentioned in my opening statement, we see Canada's carbon pricing system as an advantage in responding to the U.S. Inflation Reduction Act. It is one of the most—if not the most—economically efficient ways to go about regulating or pricing emissions, and it does so with a relatively low fiscal cost.
The next big step that Canada needs to take is implementing carbon contracts for differences, which can essentially give businesses and investors some assurance that the price on carbon will rise according to its existing schedule so that it becomes, essentially, bankable. That's often a term we hear with the production tax credits in the U.S.—that these are “bankable”. Well, putting a price on carbon and wrapping carbon contracts for difference around that makes that bankable, just as the investment tax credits are bankable.
In terms of affordability, obviously a revenue-neutral carbon tax is a critical plank to ensure that. Ensuring the ways in which those revenues are returned to households is especially important, in terms of making the whole system more progressive for the lowest-income Canadians.
There are multiple ways to do that. In many cases, the Canadian government is already taking that approach. I think there are a lot of opportunities to leverage instruments such as carbon contracts for difference, as well as investment tax credits. Then, on the private sector side, implementing a climate investment taxonomy can give businesses and investors more certainty to invest in a clean economy.
