About Us

As a parent, I hope we are leaving the planet in a state that will allow our children to survive and thrive. Every parent can identify with this goal, and it is one of the most compelling reasons to support the Union of Concerned Scientists.

The Union of Concerned Scientists is the leading science-based nonprofit working for a healthy environment and a safer world.

UCS combines independent scientific research and citizen action to develop innovative, practical solutions and to secure responsible changes in government policy, corporate practices, and consumer choices.

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 250,000 citizens and scientists. UCS members are people from all walks of life: parents and businesspeople, biologists and physicists, teachers and students. 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.
