Earthjustice works through the courts on behalf of citizen groups, scientists, and other parties to ensure government agencies and private interests follow the law. On Capitol Hill, we work to protect and strengthen federal environmental laws and preserve special places, like the Arctic.

Earthjustice, founded in 1971 as the Sierra Club Legal Defense Fund, first used the courts as a conservation tool when it saved the pristine Mineral King Valley in California's scenic Sierra Nevada Mountains from becoming the world's largest ski resort. 

Earthjustice's employees work out of nine regional offices around the country, which include an international program in Oakland and a policy and legislative team based in Washington D.C. Our regional offices and attorneys each have a unique focus, often local and national.


Earthjustice is the premier nonprofit public interest environmental law organization. We wield the power of law and the strength of partnership to protect people's health, to preserve magnificent places and wildlife, to advance clean energy, and to combat climate change.
