Is ESG investing illegal?

For fund managers, it may violate their fiduciary responsibility (to maximize returns) to their shareholders.   Apparently, the legal risk is too big for JP Morgan, State Street, and BlackRock:  

Asset managers have been walking a fine legal line. GOP Attorneys General in 2022 warned that they might be violating their fiduciary obligations and antitrust laws. House Judiciary Committee Chairman Jim Jordan in December subpoenaed BlackRock and State Street Global Advisors for documents and communications related to their involvement in “collusive” agreements.

The climate alliance’s new rules would compound the legal and political jeopardy. In its withdrawal announcement, State Street said its rules “are not consistent with our independent approach to proxy voting and portfolio company engagement.” BlackRock said the rules “would raise legal considerations.”
