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 […]

Earlier this week, on April 21, 2026, the U.S. District Court for the District of Massachusetts enjoined five secretarial orders issued by the Department of the Interior (“DOI”) and U.S. Army Corps (“USACE”) that collectively imposed sweeping constraints on wind and solar development across the United States. The Sabin Center’s Renewable Energy Legal Defense Initiative […]

Introduction As a British judge with a special interest in environmental law, I have over the last two decades taken a particular interest in the developing role of the courts across the world in response to the challenges of climate change. In this article I shall look back at my perceptions of the responses of […]

On May 2, 2025, the African Court on Human and Peoples’ Rights (AfCHPR) received a formal petition requesting an advisory opinion on the human rights obligations of African States in relation to the climate change crisis. The petition before the AfCHPR details a continent already experiencing widespread and severe impacts at approximately 1.3°C of global […]
