About Tri-valley cares

Building the future

Tri-Valley CAREs works to strengthen global security by stopping the development of new nuclear weapons in the US and promoting the elimination of nuclear weapons globally. Nuclear weapons decrease rather than increase human security. Nuclear weapons pose one of the great social, economic and ecological challenges of our time.

Tri-Valley CAREs was founded in 1983 in Livermore, California by concerned neighbors living around the Lawrence Livermore National Laboratory, one of two locations where all US nuclear weapons are designed. Tri-Valley CAREs monitors nuclear weapons and environmental clean-up activities throughout the US nuclear weapons complex, with a special focus on Livermore Lab and the surrounding communities.

our Work

Tri-Valley CAREs has been operating for over 36 years. During this time we’ve conducted original research and produced reports and analyses that have been cited by delegates to the United Nations, U.S. members of Congress, major media outlets and others. We’ve conducted numerous meetings with members of Congress, their staff and Administration officials with oversight responsibilities for the U.S. nuclear weapons complex, mobilized the community and played a pivotal role in exposing security deficiencies at Livermore Lab. We’ve helped raise awareness about the DOE’s Complex Transformation plan to revitalize the nuclear weapons complex, and helped prevent construction of numerous nuclear weapons projects across the country.

We’re passionate about regularly informing and activate thousands of our members and numerous allies so that they may more effectively raise their authentic voices to create positive social and political change.
