In July 2023, the International Maritime Organization (IMO) resolved to reduce international shipping’s greenhouse gas emissions to net zero “by or around, i.e., close to” 2050. There is a long-running debate about whether the sector should decarbonize and how it could do so in a way that is equitable for states and the shipping industry. This Article is the first to normatively define shipping’s fair share of the overall climate mitigation burden using principles of international environmental law.

The U.S. Environmental Protection Agency’s (EPA’s) enforcement program has long been the backbone of environmental enforcement in the United States. That program may now be bound for dramatic change. This Article analyzes the threats posed to the Agency’s program by the U.S. Supreme Court’s forthcoming decision in Securities and Exchange Commission v. Jarkesy, in which three constitutional questions presented cut to the core of administrative enforcement.

Supplemental environmental projects (SEPs) have received a growing amount of attention in recent years, from the Donald Trump Administration banning their use in settlements, to regulation and guidance from the Joseph Biden Administration reversing the ban, to legislative proposals prohibiting them altogether. This Article examines SEPs’ legality under existing law, focusing on claims that they violate the Miscellaneous Receipts Act and the Antideficiency Act. It begins with a brief history of SEPs’ policy evolution and the limitations on the U.S. Environmental Protection Agency’s and U.S.

As marketers across the fashion industry increasingly tout “circularity” initiatives, the reality remains that exponentially more clothes are being produced, purchased, and promptly thrown away than ever before. This Comment focuses on governmental responses to the environmental crisis created by textile waste that promote circularity in the fashion industry through extended producer responsibility (EPR) regulation of textiles.

Methane is estimated to be responsible for one-third of the global rise in temperatures from greenhouse gases; it is shorter-lived but much more potent than carbon dioxide. The United States and the European Union (E.U.) launched the Global Methane Pledge at the 2021 United Nations Climate Change Conference (COP26). At COP28’s Global Methane Pledge Ministerial last December, new strategies were announced, including the E.U.’s first-ever adoption of methane regulations and a final rule by the U.S. Environmental Protection Agency to reduce methane from the oil and gas industry.

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.
