The Trump administration is dismantling federal climate disclosure requirements for public companies, though the rules remain technically in effect for now. President Trump has taken two major actions: the SEC withdrew its defense of federal climate disclosure rules in March 2025, and the administration cancelled a proposed requirement that federal contractors disclose their greenhouse gas emissions. While the SEC stopped defending the rules before the Eighth Circuit Court of Appeals, the regulations themselves have not been formally rescinded yet, leaving companies in legal and operational limbo.
For now, public companies must still report climate-related financial risks and certain greenhouse gas emissions under rules adopted in March 2024. Large companies with public float exceeding $700 million must disclose their direct emissions (Scope 1) and energy-related emissions (Scope 2), with initial compliance deadlines arriving in 2026. However, the Trump administration’s efforts to eliminate these requirements mean companies face uncertainty about whether they’ll need to maintain climate disclosure practices long-term, and whether billions already spent on compliance will become wasted effort.

What Exactly Are Trump’s Climate Disclosure Rule Changes?
The trump administration has pursued climate disclosure cancellation on two fronts. First, on January 13, 2025, the administration withdrew a proposed rule requiring federal government contractors to publicly disclose their greenhouse gas emissions and set emissions reduction goals. This rule, which would have affected thousands of companies in the federal supply chain, never took effect. Second, and more significantly, the Securities and Exchange Commission voted on March 27, 2025, to stop defending the SEC’s federal climate disclosure rules in court—the rules that were finalized on March 6, 2024.
This second action is particularly unusual because the SEC isn’t attempting to immediately rescind the rules through new rulemaking. Instead, it’s abandoning legal defense of existing regulations while companies still must technically comply. On July 23, 2025, the SEC told the Eighth Circuit Court of Appeals that it does not intend to rescind the rules but instead believes they lack statutory authority and encouraged the court to proceed with litigation challenging them. This creates a complicated situation where the regulations remain on the books while the government no longer actively defends them. The practical effect is that public companies face genuine uncertainty about compliance obligations. A large corporation with a $750 million public float must decide whether to prepare expensive climate reporting systems for initial compliance in 2026, knowing the SEC—the agency responsible for enforcing these rules—no longer defends their legality. This is fundamentally different from simply announcing rule cancellation; instead, the Trump administration is allowing the courts to strike down the rules while companies operate under regulatory ambiguity.
What Specific Emissions Must Companies Report Under Current Rules?
The SEC’s final climate disclosure rule creates a tiered system based on company size. Large Accelerated Filers—companies with a public float of $700 million or more—must disclose Scope 1 and Scope 2 greenhouse gas emissions. Scope 1 emissions include direct emissions from a company’s operations, such as pollution from manufacturing facilities or company vehicles. Scope 2 covers indirect emissions from purchased electricity, steam, and heat used in operations. This is a significant requirement but notably narrower than originally proposed. Importantly, the SEC’s rules do not require Scope 3 emissions disclosure for any public companies, despite pressure from environmental advocates. Scope 3 encompasses the entire supply chain and use of products—the hardest category to measure and often representing 70 percent or more of a company’s total emissions.
For a major technology company, Scope 3 might include emissions from manufacturing by overseas suppliers and electricity used by consumers of its products. The SEC excluded this requirement due to measurement challenges and business objections, which means even under full compliance with current rules, public companies would not disclose their largest emissions footprint. Smaller companies classified as Accelerated Filers—those with public float between $75 million and $700 million—must also report Scope 1 and Scope 2 emissions. Companies below $75 million public float face no federal climate disclosure requirements under these SEC rules. This creates a competitive asymmetry: a mid-sized retailer with $100 million in public float must publicly report its energy consumption and emissions, while a private equity-backed competitor of similar size faces no such requirement.
How Did the SEC Withdraw Its Defense of These Rules?
On March 27, 2025, the SEC formally notified the U.S. court of Appeals for the Eighth Circuit that it would no longer defend the federal climate disclosure rules. This move effectively abandoned legal arguments supporting regulations that the SEC itself had adopted just one year earlier. The agency’s shift reflects the Trump administration’s stated philosophy that the SEC lacks authority under securities law to mandate climate disclosures. The timing is crucial for understanding the actual legal status of these rules. Companies began planning compliance systems in 2024 after the SEC finalized the rules.
Now, merely months into those compliance efforts, the agency tasked with enforcing them has signaled it won’t defend them in court. Large Accelerated Filers face their first compliance deadline for fiscal year 2025 annual reports, which they must file in 2026. Some companies have already invested millions in software, consulting, and internal systems to gather and verify emissions data—spending that could prove worthless if courts strike down the requirement. However, the SEC’s withdrawal doesn’t immediately rescind the rules. On July 23, 2025, the SEC told the court that it does not intend to rescind the rules itself but instead encouraged the court to proceed with litigation. This unusual stance means the regulations technically remain in effect while both the SEC and Trump administration position for eventual judicial invalidation. Companies cannot simply stop compliance; they must continue following current rules until a court formally voids them or the SEC initiates formal rulemaking to rescind them.
When Must Companies First Comply, and What’s the Timeline?
The first major compliance deadline is fiscal year 2025 annual reports, which Large Accelerated Filers must file in 2026. This means companies with calendar-year fiscal years must file their first climate disclosure reports in early 2026. For a company like a major financial services firm or consumer goods manufacturer, this requires gathering emissions data from all facilities, working with energy providers and supply chain partners to obtain consumption records, assigning emission factors to calculate actual emissions, and having third-party assurance of that data. The process typically takes nine to twelve months, meaning many companies have already begun 2025 data collection. Accelerated Filers (companies with $75 million to $700 million public float) face the same fiscal year 2025 deadline, creating compliance obligations for thousands of mid-sized corporations.
A mid-tier industrial company, insurance firm, or consumer products manufacturer in this category now faces the decision of whether to invest in compliance infrastructure given the regulatory uncertainty created by the SEC’s position shift. Some have already begun compliance work based on the finalized rules; others have paused initiatives pending court outcomes. The regulatory limbo creates a costly dilemma. Companies that invest in emissions tracking systems, data management software, and employee training face wasted expense if courts eliminate the requirement. Conversely, companies that delay compliance risk being unprepared if rules are upheld. Large asset managers and institutional investors have pressured companies to maintain climate disclosures regardless of federal requirements, meaning some firms may continue reporting even if SEC rules are struck down, though without the standardized framework and audit assurance currently mandated.
What About State-Level Requirements Like California’s Climate Laws?
While the Trump administration dismantles federal climate disclosure rules, California has implemented competing requirements that became effective January 1, 2026. California’s SB 253, the Climate Corporate Data Accountability Act, requires corporations with U.S. operations earning over $1 billion annually and doing business in California to publicly disclose Scope 1 and Scope 2 greenhouse gas emissions starting in 2026, and Scope 3 emissions starting in 2027. This creates a critical divergence: California requires Scope 3 emissions disclosure—supply chain and product use emissions—starting in 2027, while the federal SEC rules explicitly exclude Scope 3.
For multinational corporations or any company doing significant business in California, this means they must track and disclose the full emissions profile that the Trump-era SEC rules deliberately omitted. A Fortune 500 technology company, for example, cannot comply with federal rules by tracking only direct and energy-related emissions and ignoring supply chain impact; California law requires that company to measure and report the much larger Scope 3 category. The state-federal mismatch creates competitive and operational complexity. Companies headquartered in California or generating significant California revenue must implement comprehensive emissions tracking systems to comply with state law, while their competitors in other states may face only federal requirements (which are now uncertain) or potentially no requirements at all if the SEC rules are struck down. This regulatory divergence may ultimately force many large corporations to adopt California’s more comprehensive standards nationwide simply to operate consistently across states and maintain investor confidence.
What Happens to Companies That Already Invested in Climate Compliance?
Many corporations have already invested substantial resources in climate disclosure infrastructure. Companies purchased emissions tracking software, hired ESG reporting professionals, conducted third-party audits of emissions data, and built internal processes to comply with the SEC rules announced in 2024. If courts strike down the federal requirements or the SEC formally rescinds them, those companies face significant sunk costs.
However, investor pressure may keep many companies reporting regardless of regulatory requirements. Large asset managers including BlackRock have signaled continued interest in climate disclosure from portfolio companies, meaning companies may maintain or expand climate reporting to satisfy investor demands even if federal mandates disappear. A major industrial company might continue disclosing Scope 1 and Scope 2 emissions to satisfy its largest shareholders, even while the federal SEC rule is invalidated. This creates a bifurcated compliance world: companies with institutional investors demand climate data, while companies without significant institutional ownership may abandon reporting.
What’s the Legal and Regulatory Outlook Ahead?
The Eighth Circuit Court of Appeals will ultimately decide the fate of the SEC climate disclosure rules. The court is considering challenges to the rules from Republican-led states, business groups, and conservative organizations arguing the SEC exceeded its statutory authority. The SEC’s July 2025 statement that the rules “lack statutory authority” essentially concedes the legal argument against them, making it unlikely the court will uphold the rules as written.
Most legal observers expect the Eighth Circuit to either strike down the rules entirely or substantially narrow them. Even if the court invalidates the SEC rules, the regulatory landscape won’t return to the pre-2024 status quo. California’s SB 253 and similar state-level requirements continue expanding, and institutional investors continue demanding climate data from portfolio companies. The Trump administration’s withdrawal of the federal contractor climate disclosure rule signals broader intent to eliminate executive branch climate requirements, but private capital markets—investors, credit rating agencies, and lenders—have developed independent demands for climate information that no regulation can easily suppress.
Conclusion
President Trump’s campaign to cancel federal climate disclosure rules has effectively immobilized the SEC’s 2024 regulations while leaving them technically in effect. Large and mid-sized public companies must still prepare for their first compliance deadline in 2026, filing climate emissions data under rules that the SEC no longer defends in court.
This creates operational and financial uncertainty: companies must decide whether to invest in expensive compliance infrastructure for regulations likely to be struck down, or risk unpreparedness if the rules are upheld. Businesses operating in California or serving institutional investors face an additional layer of complexity, as state law now requires more comprehensive emissions disclosure than federal rules, starting in 2026. Companies should monitor Eighth Circuit proceedings while building compliance flexibility into their systems—infrastructure designed to satisfy California’s requirements may ultimately be mandated regardless of federal rule outcomes, making comprehensive emissions tracking a prudent business decision even amid regulatory uncertainty.
