OCC Raises Legal Concerns Over California Climate Disclosure Laws

The Office of the Comptroller of the Currency submitted a formal letter to the California Air Resources Board on Wednesday, raising significant legal and policy objections to two state laws requiring climate-related financial disclosures from businesses operating in California.
