Lecture summary: Just over a year ago, the US Securities and Exchange Commission (SEC) sought public comments on a bold and thoughtfully framed rule proposal for the enhancement and standardization of climate-related disclosure. It was a move that signaled to many that the US was finally responding to the global shift amongst investors and asset managers toward the integration of ESG data into fundamental value analysis. Today, however, as ESG issues in the US have become politically polarized and as litigation challenges loom large, the possibility of meaningful change appears more remote. Now is therefore an ideal time to spotlight the new ESG disclosure requirements in the UK and EU and, against this backdrop, to refute the claim that ESG disclosure involves “major questions” that transcend the SEC’s longstanding and clear authority to impose new reporting requirements on publicly traded companies. The UK and EU experiences likewise provide valuable perspectives in connection with other hot-button issues in the US, including: closing the public-private disclosure gap, broadening the traditional concept of materiality, and imposing mandates that require real-time disclosure as opposed to disclosure primarily at periodic intervals.
