—I'm limited in time here.
The EPA has a study, and we've talked about 30 different studies that talk about actual CO2 emissions from biofuels being about double what they replace when you put them in, life cycle-wise, from an internal combustion engine. The latest one, of course, from the Environmental Protection Agency in the United States indicates that sinks are a contentious way of looking at this, I think, more than anything else.
Let me ask my next question.
Mr. McKitrick, we've had a few witnesses here, Mr. Jaccard from Simon Fraser University being one. He famously told us, as you can appreciate, that it's the policy you need and don't worry so much about the outcome, which I don't agree with. You can comment on that. He told us that he'd reviewed 20 to 30 studies that show that biofuels produce more GHGs than the product they replace, but they are wrong, according to him, because they don't use his own dynamic analysis; they use static analysis.
Could you please comment, Mr. McKitrick?
