Per the U.S. Department of Transportation: "Pipeline transportation is the safest and most economical means of transportation for our nation's energy products.... Oil pipeline spills amount to ... less than one teaspoon of oil spilled per thousand barrel-miles." Likewise, an evaluation of the Keystone pipeline by the Obama administration State Department found that the pipeline would cut spillage by 89% as compared to using rails and tankers. On his first day in office, Joe Biden cancelled the Keystone pipeline while claiming it does "not serve the U.S. national interest."
