Our pledge to members

For eight consecutive years we have received the four-star rating from Star Charity Navigator—a distinction achieved by fewer than 2 percent of nonprofits. Your investment in the Union of Concerned Scientists is all the more valuable, because to preserve our integrity we do not accept corporate or government grants. Your gift is building a healthy planet and a safer world. UCS is a 501c3 nonprofit organization and all gifts are tax deductible.
