Keystone XL Pipeline
Keystone XL was a proposed 1,947 km long pipeline project that would have carried crude oil from Alberta to Nebraska. It was owned by Calgary-based TC Energy Corporation. The pipeline was named XL for “export limited.” First proposed in July 2008, it was the prospective fourth phase of TC Energy’s existing Keystone Pipeline system. In Canada, Keystone XL had the support of both the federal and Alberta governments. However, the project faced significant opposition and legal challenges on environmental grounds. In January 2021, United States president Joe Biden cancelled its permit on his first day in office. On 9 June 2021, TC Energy and the Alberta government announced the termination of the Keystone XL pipeline.
