Getting To Court Is The Hard Part, Michael B. Gerrard, Jessica A. Wentz

Faculty Scholarship

The article by Quilcaille and colleagues makes a convincing case that heatwaves around the world have been worsened by the combustion of fossil fuels produced mostly by a limited number of companies. This is the latest in a series of climate-attribution studies5 that are demonstrating — with increasing precision — the link between greenhouse-gas emissions and climate impacts.

Trump Epa’S Proposed Revocation Of Greenhouse Gas Endangerment Finding Raises Tangle Of Legal Issues, Michael B. Gerrard

Faculty Scholarship

On July 29, 2025, at an auto dealership in Indiana, Lee Zeldin, Administrator of the U.S. Environmental Protection Agency (EPA), announced a proposal to withdraw the Endangerment Finding for greenhouse gases (GHGs), which has been EPA’s legal basis for using the Clean Air Act to fight climate change. This action, which will surely be fought in court once it becomes final, raises a host of legal issues. This article discusses the legal basis for and significance of the Endangerment Finding; Zeldin’s principal arguments for revoking it, and challenges that will be raised to them; the range of possible outcomes in …

International Legal Guidelines For Marine Carbon Dioxide Removal Governance Under The London Convention And London Protocol, Korey Silverman-Roati, Romany M. Webb

Sabin Center for Climate Change Law

For the past two decades, parties to the London Convention and Protocol have negotiated rules, decisions, and amendments related to climate change. These efforts have principally focused on two sets of technologies – sub-seabed carbon dioxide storage and marine geoengineering. Initial discussions regarding marine geoengineering focused specifically on ocean fertilization but, more recently, the parties have considered an expanded array of marine carbon dioxide removal (mCDR) approaches, including ocean alkalinity enhancement and ocean sinking of biomass. Throughout these discussions, the parties have invoked legal principles and guidelines, like the precautionary approach, to inform their assessment of how to apply the …

Methane Removal Under The Paris Agreement, Romany M. Webb

Sabin Center for Climate Change Law

In the 2015 Paris Agreement, the international community agreed to “strengthen the global response to climate change” by limiting the “increase in global average temperatures to well below" 2 degrees Celsius above pre-industrial levels, and ideally to 1.5 degrees Celsius. As recognized in the Agreement, to stay within these limits, global greenhouse gas emissions must be rapidly reduced, “so as to achieve a balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases in the second half of this century” — a situation commonly described as “net zero.” The need to reach net zero has prompted growing …

Strange Bedfellows: Guardians For Fetuses And Future Generations, Celia Parry

Pace Environmental Law Review

In the 1970s, savvy anti-abortion lawyers began employing “fetal guardians” as a procedural mechanism to restrict abortion access. In Juliana v. United States, arguably the most important climate lawsuit from the past ten years, a “guardian for future generations” acted as a plaintiff. These forms of legal guardianship resemble each other because they both rely on property law precedent, invoke creative interpretations of guardianship, and represent future interests. This connection also presents a predicament for climate litigators and anti-abortion litigators, who don’t typically share the same agenda. To date, this intersection between fetal and future generation guardianship has not received …

Back To The Future For Climate Liability, Anthony Moffa

Pace Environmental Law Review

The Polluter Pays Principle has been a central tenet of environmental policy for decades. It provided an economic justification for compelling cleanups through the Superfund law (the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)). However, outside of that context, it has not been explicitly cited as the chief justification for much environmental law in the United States—until now. The principle has recently been invoked in state climate lawmaking. Last year, Vermont and New York became the first states to enact laws that impose liability on fossil fuel producers for climate change harms, invoking the Polluter Pays Principle and Superfund …

Arts-Based Sustainability: From New York To Malawi, Martha B. Lerski

Publications and Research

Recognizing that libraries serve multiple constituencies and subject areas, this chapter documents and advocates for development of transdisciplinary arts-based research (ABR) and culture-related projects linked to environmental challenges. Libraries contribute collections and spaces, as well as the research of library and information scientists. Libraries are currently among invisible contributors to sustainability planning and services. The chapter will link this invisibility to the value of what visual arts refer to as negative space elements in subjects ranging from traditional ecological knowledge to environmental science. Library collections, projects, and research contribute to education for sustainable development (ESD) as required to achieve the …

Decommissioning Offshore Oil And Gas Infrastructure: Report Of Proceedings, May 2, 2025 Offshore Decommissioning Workshop, Martin Lockman, Ashwin Murthy, Romany M. Webb

Sabin Center for Climate Change Law

On May 2, 2025, Ocean Conservancy and the Sabin Center for Climate Change Law organized a workshop at Columbia Law School on offshore oil and gas decommissioning in the United States. The overarching goal of the workshop was to bring together offshore law and policy experts to outline a research and policy agenda for offshore decommissioning. Within this broad goal, we sought to (1) identify key opportunities to reform offshore decommissioning law in the United States, both in the short term and over the next decade, (2) identify knowledge gaps and highlight areas for future research, and (3) begin to …

Opposition To Renewable Energy Facilities In The United States: June 2025 Edition, Matthew Eisenson, Jacob Elkin, Ivonne Norman, Rebecca Coombs, Chadol Kim, Rex Koenig, Suzan Michalski, Eric Quiroz, Josepi Scariano, Ava Teasdale, Victor Tong, Annabel Williams

Sabin Center for Climate Change Law

Increasing the amount of electricity generated in the United States to power electric vehicles, data centers, and other end uses, while simultaneously reducing greenhouse gas emissions will require deploying a massive number of renewable energy facilities at an unprecedented scale and pace. Although many renewable energy facilities are sited without a problem, local opposition often arises. The Sabin Center’s annual report, Opposition to Renewable Energy Facilities in the United States, documents legal obstacles and challenges that arise during the siting process. In particular, the report focuses on: (a) state laws and local ordinances (“restrictions”) that impede the siting and deployment …

Water Flowing Down Wall Street, Vanessa Casado-Pérez

Faculty Scholarship

Water scarcity is a perennial problem with dire consequences for the United States and governments around the world. A lack of adequate water resources is a systematic cause of environmental harm, economic damage, and societal division. Climate change has exacerbated these problems making water even more valuable and essential.

Financial actors have turned water into the new oil. These large financial actors profiteer from buying and selling water without any interest in its actual use as an input of production. Instead, they typically seek to hold these rights until dire situations, like droughts and fires, cause temporary, but large, spikes …

Legacy Liabilities For Oil And Gas Wells Under The Mineral Leasing Act, Martin Lockman, Ashwin Murthy, Romany M. Webb

Sabin Center for Climate Change Law

The federal government is the largest landowner in the United States. The bulk of federal land is controlled by the Bureau of Land Management (“BLM”), an agency within the Department of the Interior (“DOI”) that manages more than 245 million acres or approximately 10% of the land in the United States. Below the ground, BLM’s authority reaches even further. In total, BLM controls around 700 million acres of minerals — 30% of the onshore mineral resources in the United States, spanning an area larger than Argentina. The enormous scale of oil and gas production on federal land has created a …

Valuing Heat-Related Mortality Risks, W. Kip Viscusi, Clayton J. Masterman

Vanderbilt Law School Faculty Publications

Heat-related mortality risks are a substantial component of the looming costs of climate change in the United States and globally. This article presents the results from a risk-risk survey to test whether U.S. respondents place a valuation premium on mortality risks from heat relative to cancer and transportation risks. The questionnaire exploits exogenous shocks to temperatures during a heat wave and randomized elements to further test whether preferences vary with heat exposure or the age of individuals exposed to heat risks. The results provide strong evidence that there is no valuation premium in the U.S. for heat-related risks. Subjects valued …

Trump Attacks On Climate Science May Violate Numerous Federal Laws, Michael B. Gerrard

Faculty Scholarship

Starting on its first day on January 20, 2025, the second Trump administration has launched an unprecedented rollback of efforts to fight climate change. The Sabin Center for Climate Change Law’s Climate Backtracker already has 117 items.

Much of this is aimed at scientific research on climate change, or has the effect of inhibiting the conduct and dissemination of this research. Many of these actions may also violate federal laws.

This article discusses these actions, some of their legal implications, and the litigation challenges that have already been brought. It begins with actions that are specifically aimed at climate research, …

Conversation In My Parlor About Climate Change And The Call To Thoughtful Service By Lawyers With Disabilities, Gary Norman Esq. Llm

Journal of Law and Health

Pope John Paul II penned, "So much of our world seems to be in fragments, in disjointed pieces." Experts admonish that an irreparable threshold of 1.5°C for global temperatures is not a theoretical remonstrance but an imminent imperative. Is this true? This article will explore if climate change exists. I will thoughtfully respond to this question in the affirmative, exploring center-based solutions. Specifically, this article will urge that these great United States require a new generation of leaders who can embody the energy of a Brother President Theodore Roosevelt, who possesses the eloquence of President John Kennedy, and who, like …

Climate Exceptionalism In Court, Zachary D. Clopton, David A. Dana

Northwestern University Law Review

Across a range of cases, fossil fuel companies, government actors, and some judges have conceded that climate change is an exceptional phenomenon, only to argue that its exceptional nature is a reason to keep climate change out of court. These parties and judges thus seek to avoid the adjudication of climate cases on the merits, even when the neutral application of existing law would provide for jurisdiction in these cases. We term this phenomenon “climate jurisdiction exceptionalism.”

This Article provides a comprehensive account of climate jurisdiction exceptionalism, focusing on two main threads: Article III standing and state court jurisdiction. First, …

Streamlining Wildlife Regulation, Robert L. Fischman

Michigan Journal of Environmental & Administrative Law

A recent burst of revisions in the bedrock regulations governing projects that may adversely affect wildlife represents a generational shift in policy. Streamlining federal decision -making drove much of this reform. Streamlining offers a path to address climate change without abandoning a longstanding commitment to wildlife conservation. The conservation community recognizes the need to build new infrastructure to reduce the rate of climate change through air emissions. The most urgent priority is decarbonizing the electrical ~rid through renewable energy generation and a better transmission network. Adaptation to the "new abnormal" of climate-driven environmental disruption demands federal approvals for a host …

Drawing Lines In The Sand: Armed Conflict, Climate Damage And Setbacks To Climate Action, Beatrice L. Hamilton

Michigan Journal of Environmental & Administrative Law

Armed conflicts have a significant and detrimental effect on the climate system, with considerable implications for efforts to mitigate and adapt to climate change and the civilian population. Yet the environmental provisions under the law of armed conflict (LOAC), drafted some half a century ago, struggle to adequately address these concerns. This article assesses the capacity of LOAC to address conflict-driven climate damage and its cascading impacts by characterizing these harms as environmental damage and as injury to civilians. The analysis highlights opportunities for broadening LOA C's scope and offers recommendations to enhance its capacity to address climate damage and …

Tomorrow’S Climate Law, Today, Daniel E. Walters

Faculty Scholarship

The prospects for domestic legislation or international treaties that would require governments, businesses, and individuals to stop emitting the greenhouse gases that cause global climate change are particularly bleak these days. Even as the United States has recently passed its most ambitious climate legislation to date in the Inflation Reduction Act and related “green industrial policy” legislation, these successes were ultimately a compromise with politicians who refused to consider more direct controls on emissions. Assuming they survive the second Trump Administration, the green subsidies and nudges contained in these laws, coupled with a groundswell of private environmental governance, will do …

Seaweed Cultivation And Sinking For Carbon Dioxide Removal In Alaska, Ashwin Murthy, Korey Silverman-Roati, Romany M. Webb

Sabin Center for Climate Change Law

Meeting global climate change goals requires a rapid and dramatic reduction in greenhouse gas emissions. That will not be sufficient by itself, however. It will also be necessary to remove carbon dioxide, and potentially other greenhouse gases, from the atmosphere. One proposed approach involves the cultivation and sinking of seaweed.

Alaska’s coastal waters, rich in nutrients, provide ideal conditions for seaweed cultivation projects. Moreover, Alaska’s coastal waters are more vulnerable to acidification than those in lower latitudes, making aquaculture particularly beneficial in this region. Alaska has made active efforts to streamline the permitting of seaweed cultivation, encouraging research projects in …

Wildfire Smoke And U.S. Law, Michael B. Gerrard

Faculty Scholarship

Many of the most wicked feedback effects of climate change relate to wildfire smoke. In some places the greenhouse gases poured into the atmosphere by wildfires exceed the reductions achieved by all efforts to fight climate change. At the same time, climate change is a major reason why wildfires are becoming more frequent and intense. Climate change and wildfires feed each other. However, environmental law and climate policy have paid relatively little attention to wildfires. The smoke from these fires — a major cause of illness and death, even thousands of miles from the blazes — is mostly unregulated. Efforts …

Time For States To Flex Their Legal Muscles, Michael B. Gerrard

Faculty Scholarship

In these dark several years ahead, with all three branches of the federal government moving backwards on environmental protection, the states can do much to stem the retreat.

Liability Considerations For Marine Carbon Dioxide Removal Projects In U.S. Waters, Korey Silverman-Roati, Martin Lockman, Romany M. Webb

Sabin Center for Climate Change Law

Scientists have identified a number of land- and ocean-based carbon dioxide removal (“CDR”) approaches. Ocean-based approaches, also known as marine CDR, hold great potential for uptake and sequestration of carbon dioxide. However, controlled field trials in the ocean are needed to better understand the efficacy and impacts of several marine CDR approaches. Legal considerations will have a major bearing on whether, when, where, and how such field research goes forward. Previous studies have analyzed the potential international and domestic legal framework applicable to marine CDR research and subsequent deployment (if that is ultimately deemed appropriate). However, relatively little research has …

Rising Tides And Shifting Sands: Inadequacies In American Climate Responses And An Urgent Call For A Federal Climate Adaptation Policy, Armand J. Avila

Texas A&M Journal of Property Law

Climate change is an increasingly prevalent issue in policy discussions across the United States. Its effects can be observed and measured across ecosystems, industries, and legal jurisdictions, and it is felt in the homes of the people who live and work at the forefront of its impacts. Yet, the federal government’s current policies incentivize states, localities, and private citizens to make poor climate decisions and to put themselves at risk, leading to population growth and property development in some of the most at-risk areas of the country. At the same time, the federal government operates on an outdated disaster response …

The Role Of Private Liability In The Fight Against Climate Change, Matthew Salavitch

Pace Environmental Law Review

Parties have increasingly turned to courts both to seek redress for current climate-related harms and to compel states and private actors to reduce their future GHG emissions. As a result, courts around the world have been faced with the task of defining the proper role of the judiciary in fighting climate change. In the United States, however, many courts have had difficulty defining the judiciary’s proper role in providing redress for climate-related harms, especially in relation to comprehensive federal regulation of air pollution under the Clean Air Act (CAA). Considering the uncertainty surrounding the preemptive effect of the CAA on …

Climate Change, Democracy, And The Major Questions Doctrine, Joshua Ulan Galperin

St. John's Law Review

(Excerpt)

This brief Essay progresses in four parts. I will first argue that climate change is impacting the Court’s decisionmaking. Next, I will show that the significance of climate change as a modern political issue has caused the Court to downplay the statutory arrangement Congress created in the Clean Air Act. Third, I will suggest that the Court is not genuinely failing to appreciate the design of the Clean Air Act. Instead, the Court is aware of that design and feels the design goes beyond a constitutionally acceptable delegation of legislative power. Confronting the Nondelegation Doctrine head-on, however, would force …

Water Reallocation In The West: Government And Markets, Vanessa Casado Pérez

Faculty Scholarship

Water is multifaceted: it is a human right, a production input, a sacred element, an investment asset, public property, and a fugitive resource. Its reallocation is inherently difficult because of its natural characteristics and its hybrid nature that combines public ownership with private rights. The future of the U.S. West necessitates the reallocation of water resources, even with potential new water supplies. As climate change intensifies, reallocation will take various forms—all involving government intervention to some degree, from eminent domain to competitive markets. For water markets to function effectively, they require robust institutional infrastructure to prevent issues like imperfect information …

Climate Proof Electricity, Kristen Van De Biezenbos

Utah Law Review

The devastating impacts of climate change make themselves known in the form of fires, floods, droughts, storms, extreme heat and cold, and worsening socioeconomic conditions around the globe. At the same time, the U.S. electricity system has never been more vulnerable to severe weather. Even as we embark on a national project to decarbonize the electricity system by 2035, the U.S. leads the developed world in power outages. These outages are in large part due to aging infrastructure, improperly weatherized systems, vegetation crashing down on transmission and distribution lines and—perhaps most devastating of all—wildfires caused by fallen power lines in …

The Climate-Arbitration Nexus: How Legitimate Expectations Shape Investor Claims In A Decarbonizing World, M. Uzeyir Karabiyik

American University International Law Review

The global push for climate change mitigation, particularly through renewable energy promotion and fossil fuel phase-out, has sparked a surge in investor-state arbitrations. At the heart of these arbitrations lies the concept of “legitimate expectations,” which is considered by arbitral tribunals as a cornerstone of the fair and equitable treatment (FET) standard. This Article conducts a comprehensive analysis of diverse approaches adopted by arbitral tribunals in interpreting legitimate expectations in the context of climate action. It then delves into specific interpretations of this concept within two categories: disputes related to states’ renewable energy promotion policies and those that stem from …
