That's a great question.
I think it is important to keep in mind that the different ways in which the world might use less oil in the future have very different implications for Canadian oil production and the prices received here. If there is a reduction in the use of oil globally through supply-side policies that restrict production elsewhere, then that could be a world in which we have a lower use of oil globally but higher oil prices. That would tend to be associated in Canada with a trajectory of potentially rising oil production even if global oil demand is falling. In that kind of world, it would be where Canada is among the final producers of oil globally in the future.
Alternatively, if there's demand-side policies, then that might be a state of the world where prices are lower, associated with lower oil use. It's really hard to say which of these two scenarios we might be in.
In terms of the Canada Energy Regulator's more recent projections, even in a Canada net-zero world their baseline projection has oil production still rising in Canada out into the 2030s, and even as far out as 2050, producing still in Canada a little over four million barrels per day.
I'd say that climate policy and making progress on lowering emissions globally are not necessarily at odds with the viability, sustainability and financial returns that this project comes with.
