The Thin Green Line is a new short video from the Sightline Institute in Seattle showing how fossil fuel export projects on both sides of the border threaten to unleash the carbon equivalent of roughly five Keystone XL Pipelines.

As Sightline put it: Will we double-down on coal and oil use, thereby jeopardizing our chance at a stable climate? Or will we act as a thin green line, insisting that we must do better—that our economy and our children demand a cleaner future?
