Earlier this month, environmentalists scored a major win they’d spent years fighting for: the cancellation of the Keystone XL pipeline. But while that project died, there is another pipeline that’s been carrying oil sands from Canada to the US for years: Enbridge’s Line 3. Line 3 has long needed critical maintenance to operate at full capacity, and blocking work on a replacement pipeline has become another key fight for environmentalists. Today, POLITICO’s Ben Lefebvre explains the tensions around Line 3, and whether the Biden administration will step in to shut down the project. Ben Lefebvre covers energy for POLITICO.
