As a parent, I hope we are leaving the planet in a state that will allow our children to survive and thrive. Every parent can identify with this goal, and it is one of the most compelling reasons to support the Union of Concerned Scientists.
Our pledge to members
The Union of Concerned Scientists has consistently received recommendations from the United States’ premier charity rating agencies, including Charity Navigator, the Better Business Bureau, and the American Institute of Philanthropy. To preserve our integrity we do not accept corporate or government grants. UCS is a 501c3 nonprofit organization and all gifts are tax deductible.
Eighty-eight percent of every dollar donated to UCS in fiscal year 2022 directly funded our program work, with the remaining 12 percent spent on the critical administrative infrastructure and fundraising that support our programs. With an annual budget of more than $50 million, UCS continues to strengthen our unique ability to help solve our planet’s most pressing problems with the power of independent science.
