The Fate of the New U.S. Climate Change Rules Under the New Republican Administration; Certain States are Expected to Ramp Up Their Climate Change Efforts


It is no secret that the incoming Republican Administration has been skeptical of the federal government’s climate change measures, which brings further uncertainty to the SEC’s new climate change rules (the “Rules”). To be sure, there was already uncertainty surrounding litigation in the 8th U.S. Court of Appeals over the Rules’ validity. 

The new Rules for many companies were scheduled to take effect for their 2025 fiscal years, resulting in disclosure in annual reports on Forms 10-K and 20-F filed in 2026. However, the SEC will undoubtedly announce a delay of at least one year even if the SEC is successful in the 8th Circuit. The SEC had voluntarily stayed the effectiveness of its new rules in light of the litigation.

The new Administration will have a few options. For example:

The President-Elect had been critical of climate change measures in his campaign, but not all members of his team are necessarily against all climate change measures and therefore it is challenging to make any general, sweeping prediction. We will potentially see some additional color on the President-Elect’s plans when a new SEC Chairman is nominated and testifies at Senate confirmation hearings.

State climate measures are likely to be only further spurred on by the change in Administration and questions about federal action. California will press on with its rules, and other Blue states undoubtedly will follow California’s lead, which we summarize below:

California SB 219, signed into law by Governor Newsom, made some adjustments, but did not significantly impact the reporting deadlines set out above. 

Furthermore, for U.S. businesses in scope of the European Union’s global group reporting under the Corporate Sustainability Reporting Directive, there will be a heightened need to monitor the divergent approaches and expectations to corporate sustainability reporting under the U.S. and European Union regulatory regimes.
