The Financial Post reports in its Thursday edition that a recent spate of oil-train derailments in the United States and Canada has reinvigorated the debate over how Canadians and Americans transport oil. The Post's guest columnist Kenneth Green writes that the barrage of derailments continues to illuminate the folly of the anti-pipeline movement. While the vast majority of oil transported by any mode arrives safely at its destination, there are still discernible differences in relative safety. On virtually all metrics of safety, whether environmental or occupational, it is clear that movement of oil and gas is safest via pipeline, and less safe via rail. Specifically, on an apples-to-apples basis, transport one billion tons of oil over a mile by pipeline and there is a very low likelihood of leakage. The risk of a leak by rail is twice as high, at two likely incidents. Trucks are 10 times higher still, with 20 incidents likely in moving a billion tons of oil over a mile. Environmentalists who engage in anti-pipeline crusades risk causing more harm than good. Mr. Green says their pipeline-stalling actions are diverting oil to rail, oil that would otherwise be transported more safely by pipeline.
