Union of Concerned Scientists
U.S. center-left (science-based advocacy group)
Background
UCS was founded in 1969 by MIT faculty and students, including physicist Kurt Gottfried and Nobel laureate Henry Kendall. It began as a protest against the use of science for military ends during the Vietnam War, and nuclear weapons and missile defense were early concerns. Kendall chaired the group from 1973 to 1999. Over time it widened its focus to nuclear power safety, energy policy, vehicle pollution, agriculture and climate change. It now employs its own scientists and analysts, publishes reports and a blog, lobbies on policy and works to protect government scientists from political interference. It describes itself as nonpartisan and science-based. Its issue positions, such as support for emissions limits and renewable energy and opposition to rollbacks of environmental rules, generally align with Democratic and environmentalist positions, and critics on the right see it as an advocacy group. It has also drawn criticism from some pro-nuclear voices for its skeptical stance on nuclear power. In 2026 it has publicly opposed Trump administration budget proposals that would sharply cut agencies such as EPA, NIH, NOAA and the National Science Foundation. It also opposed a May 2026 proposed rule letting political appointees decide federal research funding. It says it had documented 574 administration actions undermining federal support for science as of May 31, 2026.
