The senators called on Treasury Secretary Janet Yellen and newly appointed climate counselor Ethan Zindler, a climate and clean energy research executive, to do more to protect the U.S. economy from what Yellen has described as the "existential threat" posed by climate change. The senators said they were particularly concerned about nonbank financial institutions, which also played a critical role in the 2008 global financial crisis, and said the FSOC should finalize and immediately implement a new analytic risk framework for climate-related financial risks. They also repeated earlier calls for stronger Internal Revenue Service enforcement of rules on political activity by nonprofit organizations, citing efforts by special interests to fuel climate change denial, and investigations into how such funding could be obstructing more action on the climate crisis.
