Thank you very much, Mr. Chair.
Dr. Exner-Pirot, I really enjoyed your comment with respect to how we need a climate war, not a culture war. Some of the things that we've heard at the committee today, that you've heard and that we've heard previously in committee are trying to say that virtually any type of tax credit that an oil and gas company is able to use is a subsidy, and therefore it's bad.
I'm wondering if you could perhaps point out that some of the tax credits that are being attacked as subsidies actually serve a pretty useful purpose in reducing greenhouse gas emissions.
