Mission & Focus Areas

UCS’s mission is to put rigorous, independent science into action, developing solutions and advocating for a healthy, safe, and just future. Its stated areas of work include climate change and clean energy, clean transportation, global security and nuclear-weapons risk, and the use of science in public policy and democracy. Its filing describes work that combines technical analysis with advocacy and outreach.

UCS says it awards grants to like-minded organizations tackling pressing problems. Its 2025 filing describes the grants as core support for environmental-related programs. Examples of grantees’ stated missions include Social and Environmental Entrepreneurs’ work to empower projects in social and environmental matters; GreenRoots’ work on environmental justice and community quality of life; and Environmental Protection Network’s work to advance clean air, water, land, and climate protection. These are the grantees’ missions, not UCS’s.

Grantmaking

In filing year 2025, UCS reported 15 grants totaling $410,018. Individual grants ranged from $5,500 to $119,500, with a median of $10,000. The largest reported awards were $119,500 to Social and Environmental Entrepreneurs, $100,000 to the Center for Earth Energy Democracy, and $51,018 to The Partnership Project Inc.
