Thank you, all of you, for appearing here.
Ms. Abreu, I wish I had time to ask you some questions on ITMOs, but I don't think I'm going to get there. You certainly limited the ability to use ITMOs right now, because Canada presumably is not meeting its Paris targets.
I want to focus my questions on Mr. Ragan.
Chris, in much of the work you do you operate in a theoretical world, and you're coming up with theoretical constructs that you're hoping will work in the real world. Our challenge as politicians is that we operate in a very real world in which human nature is very apparent and in full flux, and we live in a political reality that often collides with some of the objectives a theory might have.
I want to talk about the B.C. carbon tax, because it's being held up as a sort of role model for how tax policy should be crafted. You mentioned that the best carbon tax would be one that sets a price that people pay, on one hand, but in which the money is returned to taxpayers in another way—in other words, revenue neutrality.
B.C.'s carbon tax was a revenue-neutral carbon tax when it started out. Today, it's the highest carbon tax in the country: $35 per megatonne of emissions. It is no longer revenue-neutral. Why? It's because of human nature; political reality set in. You had a new government that saw a source of revenues that could be used for that government's own political priorities, and now we're left with what is essentially a tax grab, and we still see emissions in B.C. going up.
I understand that the economy is growing, but I think we can all agree that the targets in the Paris Agreement are absolute targets, so the emissions we would expect to see would be absolute reductions. It's not happening in British Columbia.
I would ask you to respond. How do we actually address the political realities and the political challenges of trying to keep a carbon tax revenue-neutral, when over the long run it's very difficult to do, given the nature of politicians—those of us around this table?
