U.S. President-elect Joe Biden may end the Keystone XL pipeline project as one of his first acts in office, a source familiar with his thinking told Reuters it could happen as early as day one. Biden, who will be inaugurated on Wednesday, was vice president when Barack Obama rejected the $9 billion project in 2015. Then two years later, Donald Trump issued a presidential permit that allowed the line to move forward. Since then the project has seen opposition by environmentalists seeking to check Canada's oil industry and Native Americans whose land faced encroachment. Construction of the pipeline is well underway and if completed, would move oil from Canada's Alberta province to the U.S. state of Nebraska. In his 2020 run for president, Biden vowed to scrap its permit once elected. The Canadian Broadcasting Corporation reported on Saturday, the words 'rescind Keystone XL pipeline permit' appeared on his list of Biden's executive actions likely scheduled for his first day. Biden's team did not respond to a request for comment, but Canada's ambassador to the U.S. said she looks forward to a decision that fits both countries' environmental protection plans. In a statement, Ambassador Kirsten Hillman said: "There is no better partner for the U.S. on climate action than Canada as we work together for green transition." Meanwhile Alberta's Premier tweeted he was "deeply concerned" by the report, adding the decision would kill jobs, increase U.S. dependence on foreign oil, and weaken U.S.-Canada relations.
