Over the last few decades, 30 states and Washington, D.C., have enacted renewable portfolio standard (RPS) programs. These programs vary substantially, with most states having a restriction or preference with respect to whether renewables are located in-state or in-region. This Article takes a cross-disciplinary approach to analyzing these programs: first, by looking at how geographic limitations may run afoul of the dormant Commerce Clause (DCC); and second, by considering empirical research on how geographic provisions affect RPS programs’ cost-effectiveness.

In July 2021, the European Commission published a proposal for a Carbon Border Adjustment Mechanism (CBAM), part of a wider package of laws aimed at implementing the European Union (EU) Green Deal. The exact design of the CBAM is in flux, and priorities will have to be set. The chief concern is the compatibility of a CBAM with the law of the World Trade Organization (WTO). This Article explores whether and how the various CBAM design options under consideration can be reconciled with WTO requirements, focusing on a possible import border adjustment scheme.

In 2009, when carbon dioxide (CO2) levels were at 387.43 parts per million, the Center for Biological Diversity and 350.org submitted a citizen petition calling on the U.S. Environmental Protection Agency to take steps necessary to institute a national ambient air quality standard (NAAQS) for greenhouse gas (GHG) emissions under §§108-110 of the Clean Air Act (CAA). For 12 years, the petition was simply ignored. Then, the day President Donald Trump left office, outgoing EPA Administrator Andrew Wheeler issued a letter denying the petition.

Scientific communities and policy experts argue that marine protected areas (MPAs) will increase the potential of marine ecosystems to tackle climate change impacts. Yet to date, there has been little legal scholarship about how to design, manage, and implement climate-resilient MPAs. This Article underscores the importance of considering climate change in the design, planning, and implementation of MPAs, and identifies mechanisms for incorporating climate change elements into MPAs.

This Article focuses on an area of rapidly evolving jurisprudence—climate liability litigation. It examines in depth the state attorney general’s complaint filed in Rhode Island v. Chevron Corp. in 2018, alleging various state-law tort claims. It explores the intensely sustained legal battles taking place between states and fossil fuel companies over whether federal courts or state courts should have jurisdiction, which in many respects is the “ballgame issue” for both plaintiffs and defendants.

People, businesses, cities, and states are increasingly burdened by extreme weather events. Drought, heat, wildfires, precipitation, hurricanes, and tornadoes are becoming more intense. Most analysts point toward an emerging trend: as the earth warms, extreme weather events are becoming more costly and more deadly, though some raise lingering uncertainties about linking climate change to specific types of weather or specific events.

With a contentious presidential election looming amidst a pandemic, economic worries, and historic protests against systemic racism, climate action may seem less pressing than other challenges. Nothing could be further from the truth.

Local governments in the coastal zone play a key role in adapting to the changing climate.

This Article argues that growing private efforts to address climate change collectively take on the attributes and functions of a governance system that could be vital to societal decarbonization. Instead of evaluating specific initiatives or actions of particular businesses, it explores the entire field of private climate action and offers new ways of thinking about the path ahead.

It is now scientifically proven that climate change is causing disruptions to the world at large. These slow-motion consequences threaten most coastal areas around the world, especially the Pacific Island nations.  Scientists predict that climate change will cause the forced displacement of people; desertification; protracted destructive wildfires; sea-level rise; ocean acidification; extreme weather events; and severe drought, which then impacts the supply of food.
