Supreme Court Limits EPA’s Authority under the Clean Air Act

After seven years, three presidential administrations, and two appearances before the Supreme Court, the Obama Administration’s “Clean Power Plan” (“CPP”)—a Clean Air Act regulation designed to limit carbon emissions from existing coal-fired power plants (and later revised by the Trump-era “Affordable Clean Energy” (“ACE”) rule)—was struck down by the Supreme Court on June 30, 2022. See West Virginia et al. v. Environmental Protection Agency et al., No. 20-1530.

Relying on Section 111(d) of the Clean Air Act (“CAA”), the Environmental Protection Agency’s (“EPA’s”) CPP set a carbon emission limit that was essentially unattainable for existing coal-fired power plants. Consequently, EPA determined that the “best system of emission reduction” for carbon from these plants was to cause a “generation shift” from higher carbon emitting coal-fired sources to lower-emitting sources, such as natural gas plants or wind or solar energy facilities. Compliance with the CPP would have required a plant operator to: (1) reduce the amount of electricity the plant generated to reduce the plant’s carbon emissions; (2) build a new natural gas plant, wind farm, or solar installation, or invest in someone else’s existing facility and increase generation there; or (3) purchase emission allowances as part of a cap-and-trade regime. See West Virginia at 8.

Charting Climate Change Cases: A Survey of Recent Litigation

Margaret Anne Hill and Stephen C. Zumbrun

Introduction

Right now, cases involving climate change are being heavily litigated in courts across the United States. Hundreds of climate change-related cases have been filed in both federal and state courts, where parties are challenging governments’ and industry’s knowledge of and contribution to climate change. In the abstract, one would think that litigation involving emissions of greenhouse gases (“GHG”) linked to climate change would largely focus on the federal Clean Air Act. Yet, climate change-related cases now involve ever-expanding causes of action, including not only claims under the federal Clean Air Act and other federal statutes, but claims under the U.S. Constitution, state law claims, and common law claims.

There are several active cases that may have major implications on the government’s role in determining the direction of climate change policy, and on private companies’ past and future liability for alleged contributions to climate change, as well as knowledge of climate change impacts on business decision-making. This article discusses notable current cases involving climate change. Continue reading “Charting Climate Change Cases: A Survey of Recent Litigation”
