The Union of Concerned Scientists (UCS) is an independent national nonprofit whose scientists and engineers work to solve some of our planet’s most pressing environmental and safety problems. UCS combines technical analysis and effective organizing and advocacy to create innovative, practical solutions for stemming the tide of global warming, sustainable food policy and agriculture, energy and transportation, fighting misinformation and reducing the threat of catastrophic nuclear war.
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.
We have offices in Cambridge, MA, Washington, DC, Oakland, CA and Chicago, IL.
