Environmental Law Institute

The Environmental Law Institute (ELI) is a nonprofit organization based in Washington, D.C., that runs legal seminars. ELI's primary audience includes legal practitioners, business leaders, land managers, land use planners, environmentalists, journalists, and lawmakers. The Institute also convenes conferences, holds seminars, and publishes original research.

In 2018, ELI created the Climate Judiciary Project, which has trained more than 2,000 state and federal judges in what it describes as its climate science and law curriculum. Concerns over CJP's influence on judges in climate cases prompted an August 2025 letter from 23 state attorneys general to the EPA requesting an end to federal grants to ELI. ELI received $637,591 from the EPA in 2024 and $866,402 in 2023. In September 2025, Republican members of the House Judiciary Committee sent a letter to ELI requesting information about external funding sources and judicial client lists due to related concerns. Later that month, the EPA announced it was cutting all ties with the ELI.
