QuickTake: Keystone XL Pipeline’s Second Chance

The video discusses the Canadian oil sands, which are abundant but produce more greenhouse gases than conventional crude. The Keystone XL pipeline, proposed by Trans Canada, aims to transport this oil. President Trump supported the pipeline, seeking to renegotiate terms to ensure U.S. construction, while Canadian Prime Minister Trudeau also supports it but emphasizes climate action. Previously, President Obama rejected the pipeline, citing environmental concerns and its impact on U.S. climate leadership. Environmentalists argue the pipeline will hinder renewable energy transition, while proponents claim it will be safer than rail transport.
