Back in the United States, a federal court in Montana has ruled that the company hoping to build the Keystone XL pipeline must conduct further environmental reviews before proceeding with construction. The ruling is the first major victory for environmentalists opposed to the pipeline since regulators approved an alternative path for it last November. The KXL pipeline would carry oil from Canada’s tar sands region in Alberta to refineries as far away as the Gulf of Mexico. In a statement, Tom Goldtooth of the Indigenous Environmental Network welcomed the ruling, saying, “The dirty tar sands crude oil that KXL would transport requires far more energy to process than other sources of petroleum, and its extraction has already destroyed hundreds of square miles of boreal forests and wetlands in Alberta. We need to keep our fossil fuels in the ground and shut down extraction of highly polluting tar sands at their source.”
