Ecology Action is a non-profit environmental organization and consultancy founded in 1970 under Internal Revenue Code Section 501(c)(3) in Berkeley, California.
The organization assists businesses, governments, and utilities in designing and implementing programs in efficient energy use, water conservation, and sustainable transportation.
Ecology Action was launched on Earth Day in 1970 as an all-volunteer, unmanned recycling donation depot for bottles and cans.
The organization persevered through the conservative backlash of the 1980s—when the state froze over half a million dollars of their grant contracts—and the Great Recession of 2007–2009.
In 2009, the organization began to renovate the former Santa Cruz Sentinel newspaper building with two other partners.
