Acterra's mission is to bring people together to create local solutions for a healthy planet.

Acterra is a regional environmental non-profit that has served Silicon Valley and the Bay Area since 1970. The organization provides people with environmental education and inspiration to improve the environment and address climate change. Acterra currently offers four programs providing thousands of adult and youth volunteer opportunities each year. Programs include: Energy Program (which includes the Green@Home to Grid Ready program, and the GoEV program), Business Partnerships for Sustainability (which includes the Business Environmental Awards, and the Silicon Valley Green Team Network) and the Environmental Library and Resource Center (which includes Acterra's fall and spring environmental lecture series).

Acterra was formed in 2000 by the merger of the Peninsula Conservation Center Foundation (founded 1970) and Bay Area Action (1990).
