I suggest that you defer the question to another time so that we can continue to hear from the witnesses. Otherwise, we could proceed immediately with the vote.
As an observation, I would say that the words carbon tax refer only to the tax on carbon. In Canada, we also have the cap-and-trade system, which is commonly known as the “carbon exchange.” Maybe the term carbon pricing, to reflect the notion of the price on carbon, would be a better choice of terminology than carbon tax.
