New oil and gas pipeline construction is increasingly controversial, with environmental and indigenous groups warning of leaks and spills, increased reliance on fossil fuels, and infringement upon indigenous land. Recent setbacks to three projects—the Dakota Access Pipeline, Keystone XL Pipeline, and Atlantic Coast Pipeline—reflect shifting legal, economic, and policy pressures facing new construction. On September 30, 2020, the Environmental Law Institute hosted a panel of experts who explored the emerging challenges facing oil and gas pipelines and discussed their future.

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.
