Union of Concerned Scientists

The Union of Concerned Scientists (UCS) is a national nonprofit organization founded more than 50 years ago by scientists and students at the Massachusetts Institute of Technology.

Our mission: The Union of Concerned Scientists puts rigorous, independent science into action, developing solutions and advocating for a healthy, safe, and just future.

Today, we are a group of nearly 250 scientists, analysts, policy experts, organizers, and communicators dedicated to that purpose.
