Union of Concerned Scientists -- Make a donation to defend science today!

Fight for science. Donate now.

When industry-funded trade groups, corporations, and climate deniers use money and connections to undermine science, our 100,000 members rally, respond, and WIN.

Backed by the best available science, we're pushing entire industries to shift towards more sustainable approaches to energy and food production. We're holding lawmakers accountable to the facts on climate change. And exposing deceptive funding of anti-science smear campaigns that have stalled progress on global warming and other life-threatening challenges we face.

You can make an impact in the fight for science and accountability right now by donating to the Union of Concerned Scientists. We don't accept funding from government or corporations. We're independent and we rely on individual member support.

When you become a supporter we'll send you our quarterly magazine, Catalyst—giving you behind-the-scenes access to our cutting-edge campaigns.
