Climate groups accept millions from charity linked to fossil fuel investments

Exclusive: Quadrature Climate Foundation is run by billionaires whose fund has stakes worth $170m in fossil fuel firms

Some of the world’s best-known climate campaign groups have taken millions of pounds in donations from a foundation run by billionaire hedge fund bosses whose investment fund has invested in fossil fuel companies, the Guardian has learned.

Groups including the European Climate Foundation, the Carbon Tracker Initiative and the World Wide Fund for Nature (WWF) have taken millions of pounds in grants over the past two years from Quadrature Climate Foundation, according to filings with the Charity Commission. WWF told the Guardian on Tuesday it would investigate the donation.
