Thank you, Mr. DeMarco. I appreciate that answer.
My next question is for Mr. Ngan or Mr. Hermanutz.
With respect to carbon pricing, it's difficult to quantify how many of the reductions we've seen since 2005.... I appreciate that we have been able to measure our emissions reductions since 1990 or 2005. I've seen all the graphs in the G7. It's challenging to identify exactly when we ought to start measuring. However, we have seen a 6% reduction in emissions, as a country, since 2005. Since 2019, those have gone down quite dramatically. That's also—not coincidentally, in my view—around the same time we started pricing carbon emissions and pollution in Canada with a federal carbon tax.
I know it's challenging to say how many of those emissions reductions are attributable to carbon pricing. Do you have an estimation or some insight for us with respect to, perhaps, a range that might be attributable?
Anybody who might have insight could answer.
