The circular economy has gone mainstream as a goal in the transitions toward a more sustainable society. Often, however, laws that promote a circular economy remain vague or narrowly focused on resource efficiency, obscuring the fact that they have multiple environmental effects and can lead to environmental trade offs. This Article examines how to properly frame circular economy laws for sustainability, focusing on product-service systems generally and the case of car sharing in particular.

On October 29, 2021, the U.S. Supreme Court granted certiorari in West Virginia v. Environmental Protection Agency, a petition filed by several states and coal companies attacking the U.S. Environmental Protection Agency's (EPA’s) regulatory authority under the Clean Air Act (CAA). The Court’s holding in this case would determine EPA’s continued ability to use the CAA—including the national ambient air quality standard (NAAQS) program—as a climate change tool.

This Comment provides a basic introduction to the Superfund removal program, a program through which millions of dollars are allocated through the U.S. Environmental Protection Agency's 10 regional offices each year for cleaning up contaminated sites that are not designated “Superfund” sites, and particularly encourages consideration of Superfund removals to address growing concerns for environmental justice.

On the final day of the 2021-2022 term, the U.S. Supreme Court released its decision in West Virginia v. Environmental Protection Agency. The majority (6-3) opinion limited the U.S. Environmental Protection Agency’s (EPA’s) authority to regulate greenhouse gas emissions from power plants under Clean Air Act §111(d), in part by invoking the “major questions doctrine.” The decision has implications for EPA’s authority both to regulate emissions from stationary sources and to regulate greenhouse gases more broadly.
