The Environmental Law Foundation (ELF) is a UK-based charity established in 1992. It focuses on providing legal support and advocacy to individuals, communities, and organizations aiming to protect and enhance the environment. ELF's mission is to ensure that socially and economically disadvantaged communities can access environmental justice through free or low-cost legal advice, representation, and technical expertise.

ELF offers a range of services, including expert legal advice on issues like pollution and land disputes, public education through workshops and seminars, and policy advocacy to influence environmental legislation. The charity collaborates with a network of solicitors, barristers, and academics to provide pro bono legal services. Additionally, ELF produces research reports and legal guides to inform stakeholders about environmental law developments and runs outreach programs to empower communities in environmental decision-making. With the support of its patron, HM The King, ELF plays a vital role in amplifying the voices of ordinary people on environmental matters.
