There is a startling lack of global regulation of the marine ornamental trade. The only international legal framework that governs the trade of marine ornamentals is the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Requirements under Appendix II help prevent traded species from reaching the point where they need stricter protections, while Appendix III targets species that range countries want help controlling in international trade. Yet both of these appendices are poorly equipped to help regulate the marine aquarium trade.

The iron and steel sector contributes nearly 7% of global anthropogenic GHG emissions. As global climate commitments tighten and industrial decarbonization becomes urgent, green steel, produced using low-carbon alternatives such as green hydrogen and renewable electricity, has emerged as a potential solution. This Comment explores how national and international regulations are shaping the future of green steel, focusing on the interplay between climate policy and trade law.

In China, the year 2024 witnessed further evolution of environmental protection and development of legislation and rulemaking. This mainly included adoption of the Energy Law of the People’s Republic of China, revision of the Mineral Resources Law of the People’s Republic of China, and adoption of a series of administrative regulations. This Comment summarizes some of the year’s major developments.

There has been an influx of “climate superfund” bills introduced and adopted in state legislatures across the country. Modeled after the federal Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), these laws are designed to recover costs from large emitters of greenhouse gases (GHGs) to pay for climate adaptation infrastructure.

The negotiations for the Global Plastics Treaty (GPT) that collapsed on December 2, 2024, were meant to be a step toward a plastics future informed by sustainable development principles. Given that no agreement has yet been reached, this Comment will discuss two broad issues that future GPT negotiating sessions must confront to produce an effective plastic life-cycle governance instrument. Part I reviews the fragmentation in current plastic waste-related governance instruments and institutions, and describes opportunities for the GPT to find synergies with those instruments.

This Article calls on the Council on Environmental Quality (CEQ) to issue guidance clarifying that concurrent decommissioning is a “connected action” under the National Environmental Policy Act for relocation, managed retreat, and protect-in-place projects aimed at replacing infrastructure in environmentally threatened Alaska Native communities.

Little has been said on how the just transition to a decarbonized world relates to the human right, recently recognized by the United Nations General Assembly, to a clean, healthy, and sustainable environment. This Article explores this relationship and how to build a framework that guides current and future climate change endeavors. It argues that the human right’s substantive and procedural content must incorporate just transition claims, which would help resolve whether and how to advocate for specific climate measures.

Combating climate change requires not only rapid reduction of greenhouse gas emissions, but also removal of significant amounts of carbon dioxide (CO2) from the atmosphere. CO2 removal (CDR) comes in many different forms, but climate scientists and policymakers are focusing on the potentially important role of large-scale use of emerging ocean-based techniques, often referred to as marine CDR (mCDR). In the United States, mCDR in domestic waters is governed by a patchwork of laws and regulations.

In 2025, the International Court of Justice (ICJ) will deliver an advisory opinion on the legal obligations of nations with respect to the mounting damage caused by climate change. This ruling will definitively restate applicable international law, provide a basis for new global policy decisions within the U.N. General Assembly, and provide a predicate for new lawsuits in national courts. To be effective, remedies for breaching a government’s duties to avert climate change will require a “collective remedy,” not merely financial compensation.

President Biden’s 2021 Executive Order No. 14008 created a new federal legal concept of “energy communities.” The Infrastructure Investment and Jobs Act (IIJA) and Inflation Reduction Act (IRA) further defined this term, with an emphasis on historical dependence on fossil energy industries. This Article summarizes and assesses current law for “energy communities” in the United States, with an emphasis on recent developments and early implementation efforts.
