On August 20, 2026, the U.S. Forest Service (USFS) published a proposal to repeal the 2001 Roadless Area Conservation Rule (“Roadless Rule”), which prohibits new road construction, commercial timber harvests and other activities on 58.5 million acres of undeveloped public lands. As detailed in the draft environmental impact statement (DEIS) accompanying the proposed repeal, USFS […]

Two major new reports, published today by the Sabin Center’s Renewable Energy Legal Defense Initiative (RELDI), highlight key challenges facing renewable energy development in the United States. The 6th edition of Opposition to Renewable Energy Facilities in the United States identifies nearly 900 state laws and local ordinances that restrict the siting of renewable energy […]

This is the second of two posts examining New Zealand’s Climate Change Response (Tort Liability) Amendment Act 2026. Part I examined the legislation’s intervention in Smith v Fonterra and situated it within an emerging international backlash against corporate climate litigation. This post asks a different question: what does New Zealand’s decision to extinguish climate tort [&#8…

This is the second of three consecutive posts on corporate climate accountability. Yesterday’s post examined the Paris Judicial Court’s June 2026 ruling in Notre Affaire à Tous et al. v. TotalEnergies SE.  On August 18, 2026, New Zealand’s Parliament enacted the Climate Change Response (Tort Liability) Amendment Act 2026 (the Liability Act), passing 67 votes to […]

The Sabin Center for Climate Change Law and the Columbia Climate School have published the summary report for the Second Conference on Attribution Science and Climate Law, held at Columbia University on June 10–11, 2026. This event brought together physical scientists, legal scholars, public health researchers, economists, and policy experts to discuss key developments in climate change […]

Last month, I attended the International Carbon Capture and Storage Summer School, hosted by the International Energy Agency’s Greenhouse Gas R&D Programme (IEAGHG) and INNO-CCUS just outside of Copenhagen, Denmark. The timing was disconcerting: I arrived on Sunday, June 28th, 2026, the day after a heatwave in Europe set all-time highs for the hottest temperatures […]

On Thursday July 16th, a group of Sabin Center staff and summer interns boarded the shuttle from Morningside Heights to travel to the Lamont-Doherty Earth Observatory (LDEO) for an incredible day of learning about the science behind the work we do to combat the climate crisis and advance climate justice. We were met at the […]

On August 4, 2026, the Court of Appeals for the D.C. Circuit handed down its long awaited en banc decision in an appeal of a preliminary injunction issued in Climate United Fund v. Citibank, the case challenging the Environmental Protection Agency’s (EPA) unlawful termination of $20 billion in federal funding awarded through the Greenhouse Gas […]

On May 26, as part of the FY 2026-27 budget, New York State enacted significant revisions to its 2019 Climate Leadership and Community Protection Act (CLCPA or Act). The amendments amount to a substantial rollback of the Act’s ambition. For the last seven years, the Act has served as the underpinning for New York’s climate […]

The proliferation of data centers across the United States represents new “loads” (i.e., sources of demand) on the electrical grid. Data centers require enormous amounts of energy to power and cool their computing systems that operate continuously or near-continuously. To meet this demand, new energy infrastructure—both generation and transmission—will need to be developed. For local […]

At every level of government, greenhouse gas (GHG) emissions disclosure regulations that saw meaningful progress only a few years ago are now in retreat. Last week, the Securities and Exchange Commission (SEC) proposed rescinding its 2024 corporate climate-disclosure rule, and New York Governor Kathy Hochul persuaded legislators to weaken the state’s landmark climate law, the […]

Data center development and its climate, environmental, and energy impacts have emerged as a central and hotly debated issue facing local governments in 2026. Various studies have explored, among other things, the large amounts of land required for data centers; their immense use of energy and water ; their greenhouse gas emissions and other contributions to […]

Interest in marine carbon dioxide removal (mCDR) has risen in the last decade as the deadlines to meet global climate temperature goals draw closer. The Intergovernmental Panel on Climate Change (IPCC) tells us that the 1.5°C and 2°C temperature targets outlined in the Paris Agreement require net zero emissions, which in turn requires some use […]

Rapid data center development is challenging local governments’ ability to manage the environmental challenges these facilities raise. Cities, towns, and counties are facing both uncertainty about the scope of those impacts and growing opposition to data centers from residents. In response, many are turning to temporary moratoria to pause data center development while they figure […]

Clean energy siting across the nation is facing enormous challenges. Local opposition is widespread and rapidly increasing in many areas. One example is Ohio, where government opposition is a byproduct of state legislation and also the result of coordinated campaigns spreading mis- and dis-information about the impacts of renewable energy projects. By the end of […]

Climate advocates may hope to see dramatic commercial breakthroughs over the next several decades that reshape emissions-intensive components of our everyday lives, such as our dietary choices, household energy use, and transportation habits. Yet transforming these consumer sectors will require not only scientific ingenuity and entrepreneurial ambition, but also nimble competition policy to addre…

Compounding their significant climate and environmental harms, fossil fuels are also volatile commodities. In 2022, Russia’s invasion of Ukraine disrupted the supply of natural gas, causing prices to spike. More recently, the United States’ war on Iran resulted in the closure of the Strait of Hormuz, one of the most important oil and gas chokepoints […]

Nick Scott, Harj Narulla, Nicholas Young, Michael Burger, Harro van Asselt, Jessica Wentz and Maria Antonia Tigre In May, the High Court of Australia (HCA) will hear MACH Energy Australia v Denman Aberdeen Muswellbrook Scone Healthy Environment Group & Anor (“Denman”), the first climate case to reach Australia’s apex court. The case concerns the New […]

We are pleased to announce that Daniel Metzger has been promoted to Director of the Sabin Center’s Cities Climate Law Initiative. In this role, Daniel will continue to research legal tools that cities and other local governments can use to advance climate mitigation and adaptation. In addition to his academic research, Daniel will also work […]
