Doubtful. KXL will only serve to lower the price of oil, not increase emissions.
“The stakes in this battle could not be higher. If Keystone XL fails to win the president’s approval, the industry will certainly grow at a far slower pace than forecast and possibly witness the failure of costly ventures, resulting in an industry-wide contraction. If approved, however, production will soar and global warming will occur at an even faster rate than previously projected. In this way, a presidential decision will have an unexpectedly decisive and lasting impact on all our lives.”
