So that's the status quo we're projecting out of this bill. You're right, we can't predict the future. We're all better at predicting the past. All we can do when we pass a bill is just assume that it's the last bill that will be passed because we can't impose projections on bills that have not even been introduced. So if this is the final word and the federal government does impose a $50 a tonne carbon tax on provinces, and that stays in place until 2030, how much would we see carbon emissions reduced by the time that year comes?
