Thank you, Mr. Chair.
Thank you to all the witnesses here. I've enjoyed your discussions. Of course, indoor/outdoor air quality is extremely important in this bill, and certainly is to all Canadians. What we can do, in some cases, is clarify what we're trying to accomplish here, as well. There has been a lot of confusion in Parliament and everywhere else on the street about the difference between smog and greenhouse gas emissions.
Maybe you could comment a little bit about that, in terms of how you feel that difference is stated.
