Thank you, Mr. Chair.
I would like to come back to what my colleague, Mr. Caron, was mentioning when he was addressing Mr. Van Iterson.
Actually, I would like to get some clarification. In your brief, you said:
“Implementing a price on greenhouse gas emissions, through a cap-and-trade system or/and a carbon tax.... ” Just to clarify—I think some of my colleagues are a bit ill-informed—can you tell us if there's a difference between a carbon tax and a cap and trade system?
