The Rockefeller Foundation, formed with wealth generated from the oil industry over a century ago, plans to make the fight against climate change central to all of its work, including its operations and investments.

In a public letter released Tuesday, foundation president, Dr. Rajiv J. Shah, acknowledged the “irony” that his organization’s founder John D. Rockefeller “made his fortune by fueling a growing United States with carbon.”

Speaking to The Associated Press in advance of the announcement, Shah said that all institutions that benefited from the development driven by fossil fuels have a responsibility to battle climate change.
