Hampden T. Macbeth is an attorney with experience in climate, environmental, and energy law and policy. As staff attorney, his work has focused on the Clean Air Act, Clean Water Act, and the congressional and EPA response to the PFAS crisis; Macbeth has also contributed to multiple State Impact Center reports on the work of state attorneys general in protecting the environment, promoting clean energy, and acting on climate.
At the State Impact Center, Macbeth developed and managed the Center’s Health and Environmental Settlements Project. The Project culminated with the release of Looking Back to Move Forward: Resolving Health & Environmental Crises, which was published by the Environmental Law Institute Press in November 2020. He edited the book and authored a chapter in the book on the National Childhood Vaccine Injury Act. The book details how seven major health and environmental liability and compensation crises were resolved to provide a rich source of insights that can inform and guide how the courts and Congress react to future challenges.
Macbeth previously served as an institute fellow at the Georgetown Climate Center, where he worked with states on Clean Power Plan implementation issues and on other policy strategies for cleaning their energy sectors. During law school, he interned at the Department of Transportation’s Office of General Counsel, the Environmental Protection Agency’s Office of Enforcement and Compliance Assurance and the Department of Justice’s Environment and Natural Resources Division. Before law school, he served as a senior legislative assistant for Congressman Adam Schiff, handling an issue portfolio that included transportation, environmental, and energy policy. Macbeth graduated cum laude from Occidental College with a BA in Diplomacy and World Affairs (international relations) and received his JD from Georgetown University Law Center, where he was managing editor of the Georgetown Environmental Law Review and graduated cum laude.
Macbeth has written extensively on the Clean Air Act, Clean Water Act, clean energy, climate mitigation programs, PFAS chemicals legislation and regulation, state leadership in the environmental and climate arena, and the National Childhood Vaccine Injury Act.
