"U.S. Democratic presidential candidate Joe Biden recently reiterated his desire to stop the Keystone XL oil pipeline project. “I’ve been against Keystone from the beginning. It is tarsands that we don’t need — that in fact is a very, very high pollutant,” he said.
This is just the latest move in a long political game with respect to Keystone XL. In 2015, Vice-President Biden supported President Barack Obama’s decision to block the pipeline. After the 2017 election, President Donald Trump restored the project. If completed, the 1,900-kilometre pipeline would carry crude oil from Alberta to Nebraska, ultimately feeding refineries on the Gulf Coast."
