How long has Earthjustice been around?

Earthjustice was founded in 1971, in the same era as our nation's cornerstone environmental laws: Endangered Species Act, Clean Air Act, Clean Water Act and National Environmental Policy Act.

Initially known as the Sierra Club Legal Defense Fund, Earthjustice was always a separate entity from the Sierra Club. We changed our name to Earthjustice in 1997 to better reflect our role as a legal advocate for a diverse, and growing, group of clients.

How did Earthjustice begin?

The NAACP Legal Defense and Education Fund — often referred to as the Inc. Fund — was the model for Earthjustice.

The NAACP was formed to eliminate discrimination against African Americans. But to end segregation, they had to overturn the 1896 U.S. Supreme Court "separate but equal" decision. To do so, a series of lawsuits were filed that were in effect a dialogue between the Inc. Fund and the Supreme Court about what "separate but equal" meant.

The Ford Foundation was a supporter of the Inc. Fund, and, like many institutions in the 1960s, it had a growing concern about the environment.

The foundation thought the model of the Inc. Fund could be translated to work for environmental protections. At the same time, the conservation movement was becoming increasingly visible and active. Shortly thereafter, the Sierra Club Legal Defense Fund (later renamed Earthjustice) was founded by a small group of attorneys.
