In a major reversal, the U.S. Securities and Exchange Commission (SEC) has voted to end its legal defense of its climate disclosure rules, effectively backing away from requiring companies to report on climate risks and greenhouse gas emissions.

This decision, announced today, allows the SEC to abandon the rule without formally rescinding it, leaving the courts to decide its fate.

A Rule Under Fire

The climate disclosure rule, introduced in March 2024 under former SEC Chair Gary Gensler, aimed to establish the first-ever mandatory climate risk reporting framework for U.S. public companies. It required businesses to disclose:

Climate risks affecting their operations
Plans to address those risks
Greenhouse gas emissions (in some cases)

Immediately after its release, the rule faced legal challenges from multiple fronts:

Nine lawsuits were filed within 10 days, including a case led by 25 Republican state attorneys general and another spearheaded by the U.S. Chamber of Commerce.
The cases were consolidated in the Eighth Circuit court, prompting the SEC to pause implementation of the rule in April while preparing its legal defense.
In August, the SEC argued in court that the rule provided valuable financial information to investors and fell within the agency’s authority.

A Political Shift & SEC's Reversal

The SEC’s decision to withdraw its legal defense follows a change in leadership after the January resignation of Gary Gensler, with Mark Uyeda becoming Acting Chairman. Uyeda, who had opposed the rule from the start, called it “costly and unnecessarily intrusive.”

His stance aligns with Trump’s SEC Chair nominee, Paul Atkins, who is currently undergoing Senate confirmation and has also opposed climate reporting mandates.

A Blow to Investor Demand for Climate Transparency

The SEC’s about-face sparked sharp criticism from sustainability advocates and investors, who argue that the rule responds to growing market demand for climate-related financial disclosures.

SEC Commissioner Caroline Crenshaw, who supported the rule, condemned the decision, accusing the agency of “hoping to let someone else do their dirty work” by leaving the courts to dismantle the rule instead of formally amending or repealing it.

Sustainable investment groups pointed to strong investor demand for climate transparency. Steven M. Rothstein, Managing Director at Ceres, noted:

"Investors have clearly indicated they require better disclosure, with $50 trillion in assets under management broadly supportive of the rule adopted in March 2024. This is clearly a step backward."

What’s Next?

While the SEC has stepped away from defending the rule, the court will still decide its fate. If the court strikes it down, the SEC could be left without a clear path to reintroducing similar regulations in the near future.

This move underscores a broader rollback of climate-focused policies in the U.S., particularly under a shifting political landscape.

Will this decision impact investor confidence in corporate climate risk disclosures? Or will private markets push companies to report emissions and risks regardless of regulatory mandates?
