Over the past year, the Sabin Center for Climate Change Law, a joint center of Columbia Law School and the Columbia Climate School, has continued to be at the forefront of efforts to develop and advance innovative legal tools to combat climate change and advance climate justice. Our team is proud to bring you the 2023 highlights showcasing our impact in the field of climate and energy law!

Our Team is Bigger and Stronger Than Ever


The Sabin Center has expanded its team to include 12 full-time attorneys in addition to the Faculty Director, Michael Gerrard, Executive Director, Michael Burger and Deputy Director, Romany Webb. We also have a growing roster of non-resident fellows and adjunct scholars contributing to our work, along with many students. As part of our annual summer internship program, we hosted 12 students from Columbia and beyond, working on a broad range of climate-related projects.


In 2023, we hired Isabel Tañedo as our first associate director of operations, and Tiffany Challe-Campiz as our first full-time communications associate.

Climate Litigation on the Rise


In recent years, there has been a significant surge in climate litigation worldwide, involving a growing range of theories and spanning diverse geographical regions. The Sabin Center provides independent scholarship and free access resources for practitioners and researchers in the field. In addition to tracking and analyzing U.S. and global climate change litigation, the Sabin Center actively contributes to legal proceedings by submitting amicus briefs in both U.S. and international contexts.

Highlighted Activities

Project: The Sabin Center's Peer Review Network of Climate Litigation includes practitioners and scholars from around the world who review the Sabin Center’s Global Climate Litigation database and ensure that it is comprehensive and up to date. The Network currently includes 137 scholars in 109 jurisdictions and 19 international or regional adjudicatory courts and tribunals or quasi-judicial bodies. The Network also hosts a series of webinars on key trends in climate litigation. The webinars can be accessed here.  


Legal Briefs:

  • The Sabin Center submitted an amicus brief to the Inter-American Court of Human Rights on climate law, human rights and climate science. The submission was in response to the Request for Advisory Opinion presented by Chile and Colombia. Read the blog here.

  • The Sabin Center also filed an amicus brief in the D.C. Circuit Court of Appeals on behalf of the National League of Cities (NLC) and the U.S. Conference of Mayors, in opposition to a challenge to EPA’s vehicle GHG emissions standards that was filed by a coalition of State Attorneys General and fossil fuel industry groups, the Texas v. EPA case.

Harnessing the Power of Carbon Management & Negative Emissions Technologies


The Sabin Center has continued to grow its work on Carbon Management and Negative Emissions Technologies. The Center continues to play a leading role in efforts to analyze and develop legal frameworks for carbon dioxide removal, with a particular focus on ocean-based removal approaches, and recently launched a new project to explore legal issues associated with methane removal.

Highlighted Activities

Policy Impacts: Romany Webb, Korey Silverman-Roati and Carolina Arlota gave numerous in-person and virtual talks on legal issues relating to carbon management and negative emissions technologies, including at the UN Science Summit and Capitol Hill Ocean Week, among other high level events.

At the Forefront of Environmental Justice


The Sabin Center worked with WE ACT for Environmental Justice on a project to develop model legislation related to environmental justice, cumulative impacts analysis, and permit renewals for polluting facilities –M.O.D.E.L for dismantling injustice.

Helping Cities Act on Climate


The Sabin Center’s Cities Climate Law Initiative (CCLI) has provided thought leadership, resources and direct assistance to dozens of cities to help them achieve their climate goals, by addressing critical gaps and helping cities navigate legal obstacles to implementation.


In July, the Sabin Center was proud to support Smart Surfaces Coalition’s Cities For Smart Surfaces project to deploy solutions to improve health, reduce inequality and slow climate impacts while helping families and cities save money.

Highlighted Activities

Legal Impacts: The Sabin Center filed an amicus brief on behalf of the League of Cities, the League of California Cities, and California State Association of Counties, in California Restaurant Ass’n v. Berkeley, a case at the Ninth Circuit Court of Appeals.

Accelerating the Clean Energy Transition


The Sabin Center seeks to advance energy system decarbonization and to encourage a more rational accounting of climate change–related impacts of energy use in the U.S. and elsewhere. We have undertaken many activities within the energy law space. Below, we highlight two projects:

Legal Pathways to Deep Decarbonization in the United States

The Sabin Center and Widener University’s Environmental Law & Sustainability Center maintain the Model Laws for Deep Decarbonization in the United States website, which provides policy makers at the federal, state and local levels with legal tools needed to transition away from fossil fuels. More than 40 pro bono law firms are at work drafting additional model laws as part of this project.  The LPDD project has, to date, authored over 70 model laws applicable at the state, local, and federal levels addressing the different recommendations in the 2019 text, Legal Pathways to Deep Decarbonization in the United States. Most recently, the project has published a model state law on studying the work force needs of a decarbonizing economy and a model federal law on amending the value for which coal projects may lease federal land to represent its true value. Earlier this year, the LPDD project published 8 model laws on amending the federal permitting process for renewable energy. The LPDD project's outreach team continues to engage state, local, and federal policymakers to educate them about the resources available at our website.

  • In August, a group of young people in Montana won a “landmark lawsuit” in Held vs. Montana, the first constitutional climate trial in the United States, confronting the state's responsibility for climate change. A judge declared that a Montana law violated this right by stopping agencies from considering climate impacts when conducting environmental reviews. Sabin Center staff was extensively interviewed by the media. A full list of the media coverage is available here. The Climate School also published a roundup of Sabin Center media coverage related to the trial.
