In 2015, the United Nations Member States, including the United States, unanimously approved 17 Sustainable Development Goals (SDGs) to be achieved by 2030. In a forthcoming book, leading legal scholars examine each of the SDGs and recommend a suite of government, private-sector, and civil society actions to help the United States achieve these goals. This Article is adapted from Chapter 15 of that book, Governing for Sustainability (John C. Dernbach & Scott E. Schang eds., ELI Press, forthcoming 2023).

The Inflation Reduction Act (IRA) of 2022 added seven new sections to the Clean Air Act (CAA) and provided the U.S. Environmental Protection Agency (EPA) with substantial new authorities and resources. This Article examines these new amendments and the EPA-related provisions of the IRA, and explains the major implications of this historic legislation.

This Article examines the nature of the threats that climate change poses and will continue to pose for salmon recovery, as well as possible legal responses to combat these threats. It also considers the future prospects of Pacific salmon in a world that will include significant climate change and other threats to preserving and equitably apportioning the salmon resource, whose environmental sensitivity and expansive life cycle will continue to pose substantial challenges for the foreseeable future.

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.

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.

The Tana River in northernmost Norway is the most diverse Atlantic salmon river in the world. Its native salmon population has declined dramatically and resulted in a fishing ban that has affected indigenous life and distressed the local economy. Concern is mounting over the secondary infestation of Pacific pink salmon, transplanted decades ago, which creates a potential threat to the river’s genetic diversity and challenges the regime structures of international fisheries.

In 2009, when carbon dioxide (CO2) levels were at 387.43 parts per million, the Center for Biological Diversity and 350.org submitted a citizen petition calling on the U.S. Environmental Protection Agency to take steps necessary to institute a national ambient air quality standard (NAAQS) for greenhouse gas (GHG) emissions under §§108-110 of the Clean Air Act (CAA). For 12 years, the petition was simply ignored. Then, the day President Donald Trump left office, outgoing EPA Administrator Andrew Wheeler issued a letter denying the petition.

State wildlife agencies commonly claim they are entitled to manage wildlife under the public trust doctrine (PTD). This assertion is frequently made in judicial proceedings, with state requests that their managerial authority be given due force throughout state, private, federal, and even tribal lands. One might conclude that a rich body of PTD practices and policies exists for wildlife; in reality, the PTD in state wildlife management proves to be ephemeral.

Over the past 50 years, tremendous progress has been made in reducing air pollution under the Clean Air Act. Nevertheless, while air quality has improved greatly for much of the nation, there are still places where the goal of attaining national standards has still not been reached. This is often true in urban locations that are affected by multiple pollution sources; typically, these areas are also environmental justice communities. Recent events have called attention to the urgent need for concrete action to address the many problems of these communities.

The U.S. Supreme Court’s opinion in Weyerhaeuser Co. v. U.S. Fish & Wildlife Service raises important questions about the scope of the Endangered Species Act’s (ESA’s) protections for critical habitat. Foremost among them is a question one might think was long settled: what is “habitat”? In a short ruling, the Weyerhaeuser Court opined that “critical habitat” must first be “habitat,” but it did not attempt to define exactly what habitat is or how much deference the U.S. Fish and Wildlife Service should get on what is both a biological and policy question.
