>> I really believe that we can be better as a country.>> Last week, Scott Pruitt was trying to ease concerns of staff at the Environmental Protection Agency. But today he was telling CNBC what his critics have feared most. That he is not convinced carbon dioxide from human activity is the main driver of climate change.
He told CNBC's Squawk Box quote, there's tremendous disagreement about the degree of impact. So, no, I would not agree that it's a primary contributor to the global warming that we see. But we don't know that yet. Pruitt said he wants Congress to weigh in, and that the administration will make an announcement on fuel efficiency standards for cars very soon, stressing that he and President Donald Trump believe current standards were rushed through.
>> I respectfully->> Pruitt is known as a climate change denier. As Oklahoma's former attorney general, he sued the EPA more than a dozen times.
