Or, it'll be transported via ship overseas, which can result in an even larger catastrophe. I agree, he dropped the ball on this one. The oil is going to be mined, it will be sold, and it will be refined - the only question is where. The carbon will enter the atmosphere, except now it'll be accompanied by the additional carbon required to ship the oil the refinery in a much less efficient manner. I can only surmise that the decision was based entirely on politics and not on common sense.
