To achieve net-zero emissions, our modelling tells us that we must first decarbonize our society as much as possible, which is to say, electrify a large part of our energy consumption with clean electricity. The second is to reduce emissions from the oil and gas sector. Our analyses show that it's difficult to do so in a cost-effective manner. We'll also have to reduce oil and gas production and make large-scale carbon capture and sequestration. We are at over 150 million tonnes a year. So between 20% and 25% of greenhouse gases emitted in Canada should be captured and sequestered to offset emissions from agriculture and other sectors.
