As a start, electricity is really the only industrial sector that has meaningfully reduced its carbon emissions since 2005. It's about 60% overall, and some of the largest reductions as a percentage are in places like Alberta, where the phase-out of coal has seen dramatic reductions in carbon emissions. We should remember this when we think about these things.
As for the opportunity for our electricity, right now, give or take, we have about 50 megatonnes of emissions, and from the Electricity Advisory Council report a couple of years ago, the opportunity to reduce the rest of the economy's emissions is about 270 megatonnes. That's a pretty good multiplier.
I would suggest that as we think about building out the electricity system, the focus should be on making sure that it's reliable, affordable and available. Broadly, that is going to be in non-emitting categories, as places like Ontario and Saskatchewan add new nuclear plants and as we build out wind and solar elsewhere and balance resources with our hydro. That gives us the opportunity to grow the system and see a shift to electrification, be it in cars or in buildings, and that will mean real and meaningful emissions reductions.
This is a place where emissions intensity, on which the electricity sector is as good as it's going to get, is great and getting better, and it really is the measure that we should think about for our climate ambitions when it comes to fuel-switching and increasing the system.
