Our story

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.

Tri-Valley CAREs’ overarching mission is to promote peace, justice and a healthy environment by pursuing the following five interrelated goals:

  1. Convert Livermore Lab from nuclear weapons development and testing to socially beneficial, environmentally sound research.
  2. End all nuclear weapons development and testing in the United States.
  3. Abolish nuclear weapons worldwide, and achieve an equitable, successful non-proliferation regime.
  4. Promote forthright communication and democratic decision-making in public policy on nuclear weapons and related environmental issues, locally, nationally and globally.
  5. Clean up the radioactive and toxic pollution emanating from the Livermore Lab and reduce the Lab’s environmental and health hazards.
