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.

The recent passing of William D. Ruckelshaus has recalled and re-invited comparisons between the Trump and Nixon presidencies. Although Ruckelshaus might be most widely remembered for the “Saturday Night Massacre,” a review of his career in the Nixon and Reagan Administrations demonstrates a through-line of sound administration and independent regulatory leadership, at times in contrast to or in spite of his political environment.

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.

We must substantially reduce carbon emissions within a short time line, and this rapid decarbonization will cause negative economic and social impacts on workers and communities dependent upon fossil fuel extraction and use. “Just transition” often refers to addressing the needs of those communities, but an equitable transition into a low-carbon future should also take into account environmental justice communities that have suffered from disproportionate exposure to environmental hazards and that could and should benefit from job creation.

This Article focuses on lessons learned from state practice in environmental justice (EJ) mapping and screening, and their relationship to the central issue of cumulative impacts—the reality that EJ communities typically suffer from a concentration of pollution sources and negative land uses as well as health and social vulnerabilities. These lessons are based on work in California and the development, use, and impact of the California Environmental Protection Agency’s CalEnviroScreen tool; the Article also examines the U.S.

While a “spaceport” may sound like a concept mostly confined to science fiction, several commercial spaceports are in operation in the United States and abroad, and more are being developed. As the name suggests, spaceports, or commercial space launch sites, are used to conduct launch and reentry operations to and from space, such as launching satellites into orbit or sending space tourists to the edge of space and back.

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.

On March 11, 2019, the National Oceanic and Atmospheric Administration published an advance notice of proposed rulemaking to amend regulations that implement the Coastal Zone Management Act’s (CZMA’s) consistency requirement. This Article places the notice in context, focusing on the CZMA’s role in state review of offshore oil and gas development and its evolution to provide a predictable framework that balances coastal state interests with the nation’s energy needs.

The principles of “common but differentiated responsibility” (CBDR) and sustainable development play an integral role in international environmental law. However, these principles have come under fire in recent years, particularly from the global North, which has grown impatient over the lack of contribution on climate change from the emerging economies. Much effort has been expended toward the establishment of greater contribution, and the shouldering of greater responsibility from these countries.

In 1990, when the Clean Air Act (CAA) was last substantially amended, atmospheric carbon dioxide levels stood at about 350 parts per million (ppm). Now they are close to 414 ppm, and the U.S.
