The SEC of 2026: Putting Environmental and Social Sustainability to the Test, but Not as Fundamental as It Used to Be: When Will the SEC Do It Now?

Under the rules put in place today, large public companies will still have to report direct emissions from their operations and energy use that are “material” or essential for investors’ understanding of a company’s financial situation. Those disclosures would begin for fiscal year 2026. The rule will be incomplete because the SEC doesn’t include scope three. But we still think it’ll be a step forward,” Rothstein said in an interview with The Verge before the rules were finalized.

More broadly, Republicans have led a charge against ESG investing, or investing that takes environmental, social, and governance factors into account. And the US faces the potential return of former president Donald Trump, who rolled back more than 125 environmental regulations during his first term — so the fate of rules on the book now could all depend on the outcome of elections this year.

The climate rules the SEC adopted Wednesday were the target of intense lobbying since they were proposed in 2022, with interest groups arguing over how much information companies should have to disclose. The rules don’t go as far as environmentalists wanted. Legal experts say it is likely the SEC rules will be challenged in court, even though the U.S. Chamber of Commerce and other business groups sued to block similar regulations that California passed in 2023.

Industry groups argued there’s no good way right now to accurately measure those emissions. Private companies with revenue of $1 billion a year or more are required by the state to report greenhouse gas pollution, including indirect Scope 3 emissions.

The new SEC rules will give investors more information about climate risks, but they don’t know what the impact will be on global warming.

“Our federal securities laws lay out a basic bargain, that investors should have the ability to decide which risks they want to take so long as companies raising money from the public make what President Franklin Roosevelt called ‘complete and honest disclosure’,” Gary Gensler, chair of the SEC, said on Gensler added that the SEC has “an important role overseeing the disclosures at the core of that basic bargain.”

“Whether climate disclosure at a global level will ever have the greenhouse gas emissions reduction effect we need, and whether it will have that effect fast enough, I think is still an open question,” says Cynthia Williams, a law professor at Indiana University Maurer School of Law. “But what this disclosure regime can do is cause companies to take climate governance more seriously.”

“Investors will be able to see more clearly which companies are sort of future-proofed,” says Williams of Indiana University. The SEC is regulating to get investor demand. Over the course of several years, investors have been asking for this information from institutional investors.

Hester Peirce was an SEC Commissioner appointed by former President Donald Trump and warned that the new disclosure rules would be a big blow to investors.

Proponents had hopes that the rules would go as far as they could. Environmentalists wanted regulators to make companies say how climate pollution comes from things like their supply chain and customers. A lot of businesses use Scope 3 emissions for most of their carbon footprint.

“The [SEC] rule is a step in the right direction,” says Kathy Fallon, director of land and climate at the Clean Air Task Force, an environmental group. It’s like going out to buy a house, but you only get the disclosures the seller wants you to know or they think are relevant to you, because it’s so watered down.

It is essential for the U.S. to have its own standards because they are what investors use to make investment decisions.
