Union of Concerned Scientists

The Union of Concerned Scientists (UCS) is an independent national nonprofit that uses science to protect our health, safety, and environment. We are scientists, engineers, economists, activists and everyday people who develop and advocate for innovative, practical solutions to some of our planet’s most pressing problems—from combating global warming and developing sustainable ways to feed, power, and transport ourselves, to fighting misinformation, advancing racial equity, and reducing the threat of nuclear war.
