On February 28, 2022, the U.S. Supreme Court heard oral arguments for the landmark West Virginia v. EPA case, involving the scope of powers delegated to the U.S. Environmental Protection Agency (EPA) through the Clean Air Act. The Court’s decision will affect administrative law, and could have major consequences for environmental law, particularly the Agency’s power to regulate greenhouse gas emissions and take action on climate change.

At this point in time, climate change pervades every aspect of contemporary life. It is a persistent current through our lives and, increasingly, throughout the law. One would be hard-pressed to find any area of law that has not or will not soon be touched by climate change. The onset of climate change has prompted decades worth of deep and wide efforts to reshape law and policy. Yet, alongside this development, there is also erosion.

The European Union, China, California, and a number of U.S. states in the Northeast are currently using emissions trading as part of their efforts to reduce greenhouse gas (GHG) emissions. However, the popularity of emissions trading as a policy tool co-exists with a well-established, and increasingly politically powerful, set of critiques of it in the United States. These critiques come from environmental justice advocates as well as some academics and other observers.
