We’ve combined science and advocacy for more than fifty years. The results speak for themselves.
Assembled below is a list of recent UCS-driven wins and major milestones, chronicling the many ways we act at the intersection of science and policy. Each success is made possible through the power of our staff, Science Network, activists, and committed members.

7 Billion Tons of Climate Pollution Avoided Thanks to New UCS-backed Vehicle Standards
The newest EPA rules will help prevent an estimated 7.2 billion tons of global warming pollution by 2055—to get there, UCS provided technical feedback, facilitated 14,000+ public comments from supporters, and rallied reinforcement in Congress.
