About Us

The Union of Concerned Scientists puts rigorous, independent science to work 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.

What began as a collaboration between students and faculty members at the Massachusetts Institute of Technology in 1969 is now an alliance of more than 500,000 scientists and everyday people. UCS members are people from all walks of life: parents and businesspeople, biologists and physicists, teachers and students. Our members understand that scientific analysis—not political calculations or corporate hype—should guide our efforts to secure responsible changes in government policy, corporate practices, and consumer choices.

Our experts work on some of the most complex and daunting problems in our history: stemming the tide of global warming, finding sustainable ways to feed, power and transport ourselves, and reducing the threat of catastrophic war. Our achievements over the decades show that thoughtful action based on the best available science can help safeguard our future and the future of our planet.

Headquartered in Cambridge, MA, UCS has offices in Washington, DC, Oakland, CA and Chicago, IL.
