In a stern warning to the Biden administration, environmental groups are cautioning that approving oil terminals could unleash a carbon catastrophe. The warning comes as the Biden administration is considering approving several oil terminals along the West Coast of the United States. The terminals, which would be used to transport crude oil from Canada and other sources, have been proposed by several companies, including Kinder Morgan and Tesoro. Environmental groups are concerned that the terminals will increase the amount of oil transported in the region, leading to an increase in greenhouse gas emissions. The groups fear that if the Biden administration approves the terminals, it will be a major setback in the fight against climate change. "We are deeply concerned that the Biden administration is even considering approving these oil terminals," said Michael Brune, executive director of the Sierra Club. "It would be a huge step backward in terms of fighting climate change, and would put the entire West Coast at risk of a carbon catastrophe." The groups are urging the Biden administration to reject the proposals and instead focus on transitioning the region to clean energy sources. "We need to move away from fossil fuels and towards renewable sources of energy," said Brune. "The Biden administration needs to understand that approving these oil terminals would be a major setback in the fight against climate change." The Biden administration has yet to make a decision on the proposals, but environmental groups are hopeful that their warnings will be heeded.
