About Us

The Union of Concerned Scientists puts rigorous, independent science to work to solve our planet's most pressing problems. Joining with citizens 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 400,000 citizens and scientists. 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 world's most complex and daunting problems: 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.

Independent Science

UCS stands out among nonprofit organizations as the reliable source for independent scientific analysis. In an increasingly complex and technical world, rigorous and objective research and analysis is essential to devise innovative and effective solutions for cleaner air, energy and transportation, to ensure food is produced in a safe and sustainable manner, and to build a future free from the threats of global warming and nuclear war.

The experts on our staff are highly respected in both Washington, DC, and state capitals, and are frequently called to testify before government committees.

UCS analysis doesn't gather dust. We collaborate with respected researchers across the world and together with concerned citizens, we actively engage policymakers, the media, and other organizations to extend the reach of our work and drive positive change.

Mission

The Union of Concerned Scientists puts rigorous, independent science to work to solve our planet's most pressing problems.

Success

Winning higher fuel economy standards for cars and SUVs nationwide, expanding the use of clean, renewable electricity by passing renewable standards in 29 states and DC, achieving federal reforms to get politics out of science at federal agencies--these are just a few of the many UCS successes in recent years.

Since 1969, the Union of Concerned Scientists has brought together the knowledge and influence of the scientific community with the passion of concerned citizens to work for a healthy environment and a safer world.
