The Keystone pipeline was an oil pipeline system in Canada and the United States commissioned in 2010 and owned by TC Energy that was to run from the Western Canadian Sedimentary Basin in Alberta to refineries in Illinois and Texas and also to Cushing Oklahoma. The pipeline had significant opposition from environmentalists. In 2015, it was temporarily delayed by President Barack Obama. In January 2017, President Donald Trump took executive action to move the project forward, but on Jan. 20, 2021 President Joe Biden signed an executive order to revoke the permit. In June 2021, TC Energy abandoned plans for the Keystone XL pipeline.
