Union of Concerned Scientists

Founded in 1969, the Union of Concerned Scientists (UCS) 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.

UCS takes on the tough issues that require long-term commitment to ensure that decisions are based on science—not political calculations or hype. We seek to limit the impacts of climate change, accelerate the transformation to a clean energy economy, advance the production of sustainable and healthy food, reduce the nuclear threat worldwide, and highlight the central role of science to a thriving democracy.
