Funding & Financials

The generosity of our members and foundation partners enabled UCS to maintain financial stability in the last fiscal year, with an annual budget of around $50 million.

This generous support is critical to our ability to maintain an independent voice. That is why we are proud of the fact that 87 percent of your donations go directly to funding Union of Concerned Scientists program work. Your support enables us to continue developing science-based solutions to help solve our planet's most pressing problems.

The Union of Concerned Scientists continues to benefit from the generosity of our more than 100,000 members and foundations, who work in partnership with us to build a healthy planet and safer world. The majority of our support—86.6 percent—came from generous individual donors through outright and planned gifts, while support from foundations represented 13.2% of our donor revenue.

Eighty-seven percent of every dollar spent by UCS in the fiscal year 2025 directly funded our program work, with the remaining 13 percent spent on the critical administrative infrastructure and fundraising that support our programs. With an annual budget of around $50 million, UCS continues to strengthen our unique ability to help solve our planet’s most pressing problems with the power of independent science.
