But privately in the climate and biodiversity sector, the mood around the Bezos Earth Fund has turned to one of growing unease. Researchers, climate policy advisers and NGO staff voiced concerns about the level of influence the organisation holds over critical environmental institutions for halting climate change and biodiversity loss, many of which now count Bezos Earth Fund among their biggest funders. Some did not want to be named due to concerns about the consequences for their own funding.

“We have seen millions of dollars paid to conservation and climate organisations. So many have taken money from the Bezos Earth Fund and I find it really worrying. There is obviously a risk of a conflict of interest,” says Holger Hoffmann-Riem from the Swiss NGO Go for Impact. “The credibility of the system relies on independence.”

One climate policy expert, speaking on the condition of anonymity, says: “In the few years since it started distributing enormous amounts of money for climate change and conservation, Bezos Earth Fund has established influence over many major initiatives and their board members.

“At this point, Bezos Earth Fund’s enormous presence in the climate and conservation space starts to look less philanthropical, and more like an attempt to take over the corporate governance system for its own interests and agenda.”
