Sierra Club v. FERC

Plain English (For Everyone)

Imagine you're building an addition to your house, and the city needs to check if it will cause problems for your neighbors. This case is like a judge telling the agency that approved a big natural gas project that they didn't do a good enough job checking if the project would harm the environment, especially regarding climate change. The approval was sent back for a more thorough review, like the city needing to do more homework before approving your addition.

For Legal Practitioners

The D.C. Circuit vacated FERC's approval of a natural gas pipeline expansion, holding that the agency's NEPA review was deficient in its consideration of upstream and downstream greenhouse gas emissions and cumulative impacts. This decision reinforces the heightened scrutiny FERC faces under NEPA for climate change considerations and signals a need for more robust environmental impact statements, potentially impacting the viability and timeline of future pipeline projects.
