Concerned by methane’s potent climate-altering emissions, a growing number of states and municipalities have embraced the phaseout of natural gas as a tool to mitigate climate change. But in April 2023, the California Restaurant Association successfully petitioned the U.S. Court of Appeals for the Ninth Circuit to overturn the city of Berkeley’s ban on natural gas infrastructure in new buildings. The three-judge panel found the ban preempted by the federal Energy Policy and Conservation Act, and in January 2024, the Ninth Circuit denied Berkeley’s petition for rehearing.

The Nuclear Regulatory Commission (NRC) and the U.S. Environmental Protection Agency (EPA) both have long-standing risk regulation regimes. To promote deployment of advanced nuclear reactors, Congress directed the NRC to reform its licensing regulations to increase the use of risk-informed, performance-based, and technology-neutral approaches. However, the NRC has doubled down on its traditional risk-management strategies, which require eliminating even the most remote and improbable risks, and which fail to account for the benefits of advanced reactors.

Climate change and invasive species are jeopardizing already endangered and threatened species, prompting the U.S. Fish and Wildlife Service (FWS) to finalize its 2023 rule allowing experimental populations to be introduced into habitat outside their historical range, as long as the areas are capable of supporting the experimental population.

This Article analyzes domestic hurdles to renewable energy development, and explores effective regulatory strategies at both the national and state levels to overcome barriers to clean energy transition. Projections indicate that the United States will need to triple its transmission grid capacity by 2050 to achieve decarbonization at the scale promised under the Paris Agreement. The transition faces major obstacles in permitting and siting, with limited transmission access and complex processes effectively obstructing the transition.

December 2023 marked 50 years since the Endangered Species Act (ESA) was signed into law. The ESA has proven resilient to numerous legal challenges and saved many species from extinction. But its overall success has been debated, as the list of endangered and threatened species continues to grow, and only 54 species have been taken off of the list completely. On October 26, 2023, the Environmental Law Institute hosted a panel of experts who explored the successes and shortcomings of the statute and discussed what might happen next as climate change increases the risk of extinction.

Congress in the 2020s has authorized three new environmentally focused grant programs relating to western waters and appropriated $450 million in multi-year funding. The Bureau of Reclamation is responsible for creating and implementing these programs, giving it a new tool and resources for addressing stubborn environmental problems—some caused by the Bureau’s many dams.

Agrivoltaics, the concept of using solar energy systems to enhance agricultural production and generate renewable energy on the same plot of land, offers a lifeline to beleaguered farmers and  communities facing water shortages, cost increases, and marginal agricultural profitability. This concept seeks to aid California in its ambitious renewables portfolio standard, and could reduce the impacts of climate change and the toll agricultural operations take on the San Joaquin Valley’s groundwater resources.

U.S.-Canadian management of marine migratory species is a particularly rich place to understand the complex relationship between migratory science, conservation, and law. The two nations share a large border, have a long-lasting historic friendship, and already collaborate extensively. However, the relationship is not without contention. The substantial economic interests in the oceans and differences in governance structure have not infrequently frustrated efforts at cooperative management.

On August 29, 2023, the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers issued a direct final rule that revised the “waters of the United States” (WOTUS) definition rule. This rule amended the final WOTUS rule, previously published in January 2023, to be consistent with the Supreme Court’s May decision in Sackett v. Environmental Protection Agency. On September 14, the Environmental Law Institute hosted a panel of experts to analyze the new rule and discuss its regulatory and policy consequences.

Communities around the world are seeking to acknowledge nature’s rights through legal tools and litigation. This Article provides an overview of recent developments in earth law movements, including Rights of Nature, Rights of Rivers, and Ocean Rights, and considers the potential impacts these ecocentric conservation measures could have on Indigenous peoples and local communities.
