I'll start and then turn to Derek.
The number that was discussed, the 3%, I assume is with reference to a statement about Canada's absolute emissions relative to a previous year. Of course, that doesn't take into account avoided emissions—in other words, what the emissions would have been.
Emissions, as we know, have grown steadily and increasingly for decades, until the introduction of carbon pricing and complementary measures. For a fair kind of attribution of the impact of carbon pricing, one needs to account for not just where we are today but all of the emissions that have been avoided as a result of those measures.
Thanks for the question.
