What the SEC's proposal to scrap its climate disclosure rules means for US listed companies and their European counterparts

The US Securities and Exchange Commission proposed on Friday to rescind its climate related disclosure rules in full. The agency argued the requirements exceeded its statutory authority and would impose costs on public companies not justified by the resulting information provided to investors. The move marks a decisive reversal of rules that had been years in the making and signals a fundamental shift in the regulatory posture of the world's largest capital market regulator.

For companies listed on US exchanges, the immediate practical effect is the removal of a federal mandate to disclose Scope 1, Scope 2, and Scope 3 emissions, transition risks, and climate governance structures. Companies that had already begun building data infrastructure to satisfy the original rules now face the question of whether to maintain that investment or scale back. The decision creates particular complexity for multinationals that must simultaneously satisfy CSRD requirements in the European Union, where mandatory climate disclosure under ESRS E1 remains fully in force.

European subsidiaries of US parent companies, and European companies with US listings, sit in the most complicated position. They cannot simply align to the more permissive US posture because their European operations remain subject to CSRD obligations under Article 19a of the directive, including double materiality assessments and ESRS E1 climate disclosures covering physical and transition risks. In house ESG managers at these firms will need to maintain two distinct reporting tracks, absorbing the administrative burden of divergence rather than harmonisation.

The SEC's stated reasoning, that the rules would impose costs not justified by information benefits to investors, directly contradicts the direction of travel in European capital markets regulation, where regulators have consistently treated climate information as financially material. Procurement leads and CFOs at European companies should watch whether US institutional investors begin to demand voluntary disclosure in the absence of mandatory rules, which has historically been how voluntary frameworks have expanded in the US market. The gap between mandatory and voluntary could prove shorter than the SEC's proposal implies.

The broader picture is one of accelerating divergence between the two largest regulatory regimes for corporate sustainability disclosure. The IFRS and GRI collaboration to align sustainability reporting standards, reported this week, takes on added significance in this context: international standard setters are moving toward coherence precisely as national regulators in the US move away from it. For European ESG professionals, the practical takeaway is that CSRD remains the operative compliance framework regardless of what happens in Washington, and internal reporting programmes should continue to be resourced accordingly.
