Okay. That's a big half. Let's try to cover off some of that.
The question about whether oil and gas-related emissions.... The two biggest sources of emissions in Canada are oil and gas and transportation, as I think you are aware. Whether oil and gas emissions will decline...and they do need to decline for Canada to meet its 2030 target and, obviously, meet the 2050 net-zero target.
Can they decline without the imposition of a cap? Is that what you're asking? Conceivably they could because there are so many different tools that you can use to reduce emissions. Whether it's a regulation, a cap, an incentive or a carbon price, there are a whole bunch of different tools. Our office isn't here to say which tools you should use for every one, but I know that the federal government is thinking of imposing an oil and gas cap. It could achieve reductions through a range of different tools, though.
I should add, though, that this historical and present belief that oil and gas production can continue to rise in Canada, especially from the more carbon-intensive sources, but we could still have a net reduction in emissions because of efficiencies hasn't been the case. We've had increases in efficiencies over the last 30 years, but the total volume of production has outpaced the efficiencies so that many of those efficiencies are drowned out by the overall increase in production.
Canada has to get a handle on that and either make vast improvements in efficiency or figure out something like a cap on emissions, if it's going to actually add up to the 40% target in 2030 and net zero in 2050.
