A secretive funding organization called Donors Trust spent the last decade funneling vast sums of money to an array of think tanks and activist groups, all dedicated to undermining the science of climate change and heading off the progress of climate policy. That’s according to reporting last week by The Guardian’s Suzanne Goldenberg and a recent analysis by Greenpeace. Working in concert with its sister organization, Donors Capital Fund, Donors Trust provided critical funding to some of the leading lights in the climate denial campaign: From 2002 to 2010, Americans for Prosperity received $11 million from Donors Trust, the Heartland Institute received $13.5 million, and the American Enterprise Institute received more than $17 million.
