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.

The U.S. Supreme Court’s opinion in Weyerhaeuser Co. v. U.S. Fish & Wildlife Service raises important questions about the scope of the Endangered Species Act’s (ESA’s) protections for critical habitat. Foremost among them is a question one might think was long settled: what is “habitat”? In a short ruling, the Weyerhaeuser Court opined that “critical habitat” must first be “habitat,” but it did not attempt to define exactly what habitat is or how much deference the U.S. Fish and Wildlife Service should get on what is both a biological and policy question.
