Nebraska’s Supreme Court gave final approval to the Keystone XL pipeline’s proposed route through its state, and just like that, the Obama administration has run out of plausible reasons for not making a decision on the controversial project.President Obama has long insisted that the fate of Keystone is in the hands of the State Department, going so far as to promise a veto this week to any proposed legislation out of Congress approving the pipeline. Nearly one year ago the State Department issued a report affirming what many have believed: that the pipeline will not have an impact on global emissions, operating under the logic that the oil it would carry is going to come out of the ground with or without this conduit.Since then, a legal dispute over whether the Nebraskan governor was right to approve the pipeline’s route through his state has given the President time to defer a final decision on Keystone, but the Nebraska Supreme Court’s decision today dismantles this last regulatory hurdle.Greens have made Keystone a make-or-break issue, eschewing facts in favor of a symbolic stand-off with a secondary piece of infrastructure for what is an admittedly dirty fossil fuel source. On the facts alone, Keystone ought to have been approved long ago, but the political rhetoric surrounding the project has sentenced it to regulatory limbo. The White House said it will review Nebraska’s decision, but it’s clear that President Obama now has to make a decision. Let’s hope that comes soon—there are so many more important energy policy issues worth discussing.
