Amazon founder and CEO Jeff Bezos  announced the launch of the Bezos Earth Fund, a new global initiative that will commit $10 billion to combating climate change.

Bezos will begin issuing grants in connection to the fund this summer. 

Bezos said the fund will support scientists, activists, nongovernmental organizations (NGOs) and “any effort that offers a real possibility to help preserve and protect the natural world.”

“Climate change is the biggest threat to our planet,” he said. “I want to work alongside others both to amplify known ways and to explore new ways of fighting the devastating impact of climate change on this planet we all share.”

The fund will provide donations — not investments that Bezos could profit from, The New York Times reported.  The initiative is reportedly separate from Amazon’s work.
