This article highlights the results of the Environmental Law and Policy Annual Review (ELPAR) article selection process and reports on the environmental legal scholarship for the 2018-2019 academic year, including the number of environmental law articles published in general law reviews versus environmental law journals, and the topics covered in the articles.

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.

This Article, adapted from Chapter 16 of What Can Animal Law Learn From Environmental Law?, 2d Edition (ELI Press, forthcoming 2020), explores existing and potential wildlife conservation policies that could play a vital role in mitigating global climate change. It describes how climate change is impacting wildlife and biodiversity around the globe and reviews the history and current state of U.S. policy, including how the federal government currently manages climate change issues under the ESA.

The livestock sector is one of the planet’s primary causes of resource consumption and environmental degradation. Approximately 99% of meat and other animal products in the United States are from factory farms, and the number of concentrated animal feeding operations (CAFOs) continues to grow. This Article, adapted from Chapter 8 of What Can Animal Law Learn From Environmental Law?, 2d Edition (ELI Press, forthcoming 2020), examines animal agriculture in the U.S and the associated problems.

The role that cost-benefit analysis (CBA) plays in regulatory decisionmaking is at a crossroads, as is the role played by the agency that oversees its implementation, the Office of Information and Regulatory Affairs (OIRA). The Trump Administration has largely demonstrated agnosticism toward CBA; this has left many to question whether OIRA can still play the role of ensuring quality analysis while serving as the eyes and ears of the president in overseeing regulation.

In the first decades of the 21st century, those working to assure that earth continues to be a viable home for humanity as well as for all other life have been in a crisis regarding their purpose and direction. This is a departure from the past century and a half, when the giants of conservation and environmental protection—personalities such as John Muir, Rachel Carson, and David Brower— were certain of their cause and the actions needed to sustain it.

This Article analyzes the recent proliferation of “tag-gag” laws aimed at undermining the emerging plantbased and cell-based food industries. It examines potential constitutional challenges to these laws, including those based on the First Amendment, the dormant Commerce Clause, Supremacy Clause, and Due Process Clause, as well as the likely arguments that states will proffer in their defense. It concludes with a discussion of the consequences and implications of various outcomes of these cases, and how animal advocates can responsibly bring these types of constitutional challenges.

In the absence of a national mandate to intensify use of renewable energy, many corporations are increasing their own reliance on renewables. Numerous utilities are likewise transitioning toward wind, thermal, and solar power. But renewable energy continues to face challenges, including battery storage, grid expansion and incorporation of renewables into the grid, initial project costs, and regulatory barriers. How are utilities and energy-consuming companies increasing their renewables portfolios while navigating this terrain?

We are practitioners for the City of Philadelphia with extensive experience in cases and analysis regarding the extent to which the Commonwealth of Pennsylvania has, or has not, preempted local regulation in various subjects of concern to the City. As City attorneys, our perspective is based in our role as advocates for the preservation and defense of the City’s exercise of its home rule powers. In considering the city-state relationship, many of the practical, political and cultural issues addressed in Prof. Richard C.

The Endangered Species Act defines an endangered species as one at risk of extinction “throughout all or a significant portion of its range.” The U.S. Department of the Interior (DOI) has repeatedly defined “significant portion” to mean an area of the range essential to species persistence. This definition is redundant, and various iterations of the definition have been struck down in the past. At the same time, other proposals to list a species only in a portion of its range fail to satisfy the statutory requirements.
