The Planning and Conservation League Foundation is a nonprofit organization founded in 1972, whose mission is to protect the California environment and ensure that California continues to be an attractive, livable and equitable state by engaging in cutting-edge environmental public policy research and educating and empowering local communities to participate in local and state environmental decision making processes.

The research of the PCL Foundation is made available to the Planning and Conservation League, other organizations, state and local government decision-makers, and the general public to serve as a catalyst for public policy change to solve critical environmental problems.
