Two carbon pricing bills were introduced during the 115th Congress. Reps. Carlos Curbelo (R-Fla.) and Brian Fitzpatrick (R-Pa.) introduced the MARKET CHOICE Act during the summer of 2018. Reps. Ted Deutsch (D-Fla.) and Francis Rooney (R-Fla.) introduced the Energy Innovation and Carbon Dividend Act (Energy Innovation Act) in November 2018, and reintroduced it early in the 116th Congress, where it presently has more than 65 cosponsors. By different methods and with different comprehensiveness, both of these bills place a Pigouvian tax on greenhouse gas (GHG) emissions.

Established in over 65 countries and territories, marine protected areas (MPAs) embody a range of habitats, enable the provision of fundamental ecosystem services, protect marine biodiversity and cultural resources, and provide spaces to conduct cutting-edge research and implement innovative policies. Yet management of MPAs can face challenges, including the lack of adequate tools, the need for rules to secure comprehensive monitoring, the vastness of the ocean, and more.

The United States owns, on behalf of all Americans, approximately 30% of the nation’s land, totaling more than 600 million acres. These lands are overseen by the Bureau of Land Management (BLM) in the U.S. Department of the Interior (DOI).

The U.S. Department of the Interior and National Oceanic and Atmospheric Administration recently finalized comprehensive changes in how the Endangered Species Act (ESA) is implemented. These changes address the species listing process, critical habitat designations, protections for threatened species, and the §7 consultation process.

As climate change worsens, so does the risk of wildfires. This is especially so in already hot, dry areas such as the western United States. Adding to this problem is the rapid growth of the wildland-urban interface (WUI).

The National Highway Transportation Safety Administration (NHTSA) and the U.S. Environmental Protection Agency (EPA) have proposed a new reading of the Energy Policy and Conservation Act of 1975 (EPCA) that governs federal fuel economy standards. The regulations would relax federal greenhouse gas tailpipe standards and fuel economy standards, and preempt emissions standards put in place by California and adopted by other states.

Federal dams have been the focus of major disputes involving application of the Endangered Species Act (ESA), especially its §7 prohibitions on federal actions causing jeopardy to protected species. Operating agencies and project beneficiaries have sought to keep the ESA from restricting dam operations, including by arguing that such operations are non-discretionary and thus exempt. In proposing new ESA implementing rules, the Trump Administration suggested, but did not formally propose, that ongoing federal actions should be considered part of the “environmental baseline” for §7 purposes.

Economywide legislation to address climate change will be ineffective unless it addresses greenhouse gas emissions from agriculture and land use. Yet incorporating these sectors into the most popular policy proposal—a carbon tax—carries legal risk that policymakers and legal commentators have ignored. This Article explores whether a carbon tax, as applied to agriculture and land use, is a direct tax within the meaning of the Constitution; it concludes that text, history, and Supreme Court precedent up through National Federation of Independent Business v.

Greenhouse gas emissions from transportation in the United States have remained persistently high. One cause is common low-density land use patterns that make most Americans dependent on automobiles. Reducing these emissions requires increasing density, which U.S. local government law makes difficult to achieve through the political process. Mount Laurel, a 1975 New Jersey Supreme Court case that addressed an affordable housing crisis by restraining local parochialism, provides a potential solution.

This year, 2019, marks the 20th anniversary of the removal of the Edwards Dam, one of the first functioning hydroelectric dam to be decommissioned and removed in the United States. It was also the first to be removed under the Federal Energy Regulatory Commission’s (FERC’s) asserted power to compel such a removal without compensation, an assertion raising legal questions that have yet to be fully resolved. As our hydroelectric infrastructure continues to age, these questions may again come to the forefront.
