The Union of Concerned Scientists stands out among environmental organizations as the reliable source of sound scientific information. UCS is the most effective group to combine credible scientific analysis with effective citizen advocacy to bring about policy change. We work with respected researchers, many of them leaders in their fields, and members of prestigious academies and professional associations, including many Nobel laureates. The reports and analyses we produce are used by policymakers, the media, and our colleagues in other organizations to help shape legislative debates on important environmental issues.

UCS reports don't just sit on the shelf. In partnership with tens of thousands of citizens, we use our information to bring about policy changes that will protect and improve the health and safety of our environment globally, nationally, and in our communities.
