Union of Concerned Scientists

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

Our mission is to use rigorous, independent science to solve our planet's most pressing problems. Joining with people across the country, we combine technical analysis and effective advocacy to create innovative, practical solutions for a healthy, safe, and sustainable future.

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