This Article focuses on an area of rapidly evolving jurisprudence—climate liability litigation. It examines in depth the state attorney general’s complaint filed in Rhode Island v. Chevron Corp. in 2018, alleging various state-law tort claims. It explores the intensely sustained legal battles taking place between states and fossil fuel companies over whether federal courts or state courts should have jurisdiction, which in many respects is the “ballgame issue” for both plaintiffs and defendants.

This Article discusses the Trump Administration’s main actions to undermine the role of science in public policy and the consequences for cost-benefit analysis involving climate change policies. It analyzes the specific attacks on science and their impact on relevant policies, namely, the rollbacks of the Clean Water Rule, the pesticides ban, the Clean Air Act, and the Clean Power Plan, as well as modification of the National Environmental Policy Act and regulations promoting fuel efficiency, and the flexibilization of environmental enforcement during the COVID-19 pandemic.

As in prior years, the National Defense Authorization Act for Fiscal Year 2020 contains a variety of provisions setting U.S. Department of Defense priorities for energy, environmental, and natural resource issues. These include measures that represent some degree of consensus on these often-politicized topics.

With the increased risk of flooding due to climate change, potential liability from construction and maintenance of flood control measures is a major consideration governments must consider when planning and building them. This Article discusses how the Supreme Court’s decision in Arkansas Game & Fish Commission v. United States (AGF) laid the groundwork for a new form of takings that the authors term “negligent takings,” increasing the likelihood that the government will be liable after a flooding event.

Per- and polyfluoroalkyl substances (PFAS) are a toxic, environmentally persistent class of chemicals that have been used widely in consumer products. Despite growing evidence of adverse health effects associated with PFAS exposure, the U.S. Environmental Protection Agency has not yet promulgated a legally enforceable standard for any of the individual chemicals in the PFAS group. This has resulted in largely unrestricted disposal of PFAS waste and dispersal of these persistent chemicals throughout the environment.

Artificial intelligence (AI) and complex machine learning algorithms have come to play a profound role in many of our day-to-day activities.

The COVID-19 pandemic will have far-reaching and even transformative implications for environmental law.

As companies increase their environmental, social, governance (ESG) reporting and statements in response to market and shareholder demands, plaintiffs have pursued with growing success legal challenges to company claims and disclosures related to ESG performance. Similarly, inventive theories are being put forward to directly attack companies for alleged ESG-related performance and operational deficiencies. In both arenas, there has been a recent growth in efforts to hold companies accountable for supplier misconduct.
