Questions presented
SCOTUS records, cert granted 29 Oct 2021
In 2015, the EPA promulgated its "Clean Power Plan," which for the first time imposed carbon dioxide emissions limits on existing coal- and gas-fired power plants. The EPA developed those standards based not on any technology that the plants could themselves apply in their operations, but instead on an industrywide system of "generation shifting"-a cap-and-trade- style regime that effectively required many existing power plants to be shuttered or to scale back while subsidizing renewable energy sources. This Court stayed that rule even before any lower court had reviewed it. And no court ever did review it, because the EPA soon changed course. It repealed the Clean Power Plan, reasoning that the Clean Air Act authorized it only to promulgate standards based on technology actually applicable to a given existing source-not to devise its own national, systemic solution to greenhouse gas emissions. Now, in the whiplash-inducing opinion below, the D.C. Circuit has held that this repeal was arbitrary and capricious, because the Act supposedly does grant the EPA the requisite authority after all. With that background, the question presented is: Whether 42 U.S.C. § 7411(d), which authorizes the EPA to impose standards "for any existing source" based on limits "achievable through the application of the best system of emission reduction" that has been "adequately demonstrated," grants the EPA authority not only to impose standards based on technology and methods that can be applied at and achieved by that existing source, but also allows the agency to develop industry-wide systems like cap-and-trade regimes.
Opinion summary
Etalia.ai summary of the majority opinion
The case involves the North American Coal Corporation challenging the Environmental Protection Agency's (EPA) authority to regulate greenhouse gas emissions under the Clean Air Act. The central issue was whether the EPA overstepped its regulatory powers by implementing broad measures aimed at reducing carbon emissions from power plants, which are significant contributors to climate change. The Supreme Court examined if such actions were within the scope of congressional intent when it granted regulatory authority to the EPA or if they constituted an overreach requiring explicit legislative approval. Ultimately, this decision had significant implications for environmental policy and administrative law, particularly concerning how federal agencies interpret their mandates in addressing complex issues like climate change.
