Thank you. Thank you, Mr. Chair.
I have a quick follow-up question on the carbon tax.
We know it's a signature piece of legislation in regard to tackling climate change, according to this government, but we do not have, to my understanding, any metric through which we are measuring how many megatonnes of carbon emissions have actually been reduced as a result of the carbon tax.
Is that correct, Mr. DeMarco—yes or no? I don't believe we have a metric, do we?
I also have a quick follow-up.
