As was noted earlier, there is a lot of consensus around the cost-efficiency and effectiveness of this model, but I take your point that it's important to point to some concrete examples, and there is a lot of evidence for that.
We can look at our own country, at British Columbia. Outside estimates see that the reductions in emissions in the province since its carbon tax was implemented in 2008—I think it's a range of emissions reductions—are between 5% and 15% lower than what you would have had in the absence of this carbon tax. That's one example. There are a lot of other examples from different jurisdictions around the world where we see the effectiveness.
I guess I'd flag the point I made earlier, which is that it's a common mechanism to basically put a price on pollution to change the incentives people have when they make choices. Whether it's to individual consumers, to businesses or to households, it creates a signal and an incentive to make lower-carbon choices. It's as simple as that.
There is one example that I don't think gets flagged as often, but I'll point to it again. This is an old mechanism, but it's a similar tool that was effective in eliminating acid rain. This is going back many decades, but these are kind of the same market tools that allow emissions of pollution, whether it's greenhouse gas pollution or other forms of pollution, to be reduced in a way that doesn't prescribe how and enables low-cost reduction.
We can follow up to provide other examples, but there is a lot of evidence we could point to in order to show the effectiveness. There is a lot of support across stakeholders from a lot of industry and the big banks in Canada. We do have a lot of support. We're still working through some of the details of how; for example, the output-based pricing system is under development. I think we could provide some follow-up examples, if that would be helpful.
