Environmental Disclosures: SEC Rules, Liability, and Safe Harbors

Public companies filing with the SEC must disclose material environmental information as part of their regular reports under Regulation S-K, and the SEC’s environmental disclosure requirements today rest almost entirely on those long-standing materiality-based rules rather than on the climate-specific rule adopted in March 2024, which the agency stayed weeks later and stopped defending in court in March 2025.¹ Nothing about the stay relieves companies of their obligation to report material environmental risks, compliance costs, and pending environmental litigation. Those obligations remain fully enforceable, and misleading disclosures still trigger civil penalties, private lawsuits, and, in willful cases, criminal prosecution.

What Public Companies Must Disclose Now

Several Regulation S-K provisions capture environmental information whenever it is financially material to the business. None of them uses the word “climate,” but each reaches climate risks and other environmental matters when materiality is met.

Item 101 (business description) requires disclosure of the material effects that compliance with federal, state, and local environmental laws may have on capital expenditures, earnings, and competitive position, along with estimated capital expenditures for environmental control facilities.
Item 103 (legal proceedings) requires description of any material pending environmental lawsuit or regulatory proceeding. Environmental enforcement actions are specifically carved out of the “ordinary routine litigation” exception, so they must be disclosed even when comparable non-environmental cases would not.
Item 105 (risk factors) requires disclosure of the most significant factors making an investment risky, including climate-related risks when material.
Item 303 (management’s discussion and analysis) requires narrative discussion of known trends and uncertainties reasonably likely to have a material effect on financial condition or results. Water scarcity affecting manufacturing, or rising insurance costs from extreme weather, would be addressed here.

Two catch-all rules sit on top of these items. Securities Act Rule 408 and Exchange Act Rule 12b-20 require companies to disclose any additional material information necessary to keep their filings from being misleading.² A company aware of a material environmental risk that says nothing about it can face liability under these rules alone. No new regulation is required.

These obligations apply to every public company filing with the SEC, regardless of size. Materiality is the pivot point: if a reasonable investor would consider the environmental fact important to an investment decision, it belongs in the filing.

Status of the 2024 Climate Disclosure Rule

On March 6, 2024, the SEC adopted “The Enhancement and Standardization of Climate-Related Disclosures for Investors,” which would have required standardized reporting of climate risks, greenhouse gas emissions, and related financial impacts.³ Industry groups sued almost immediately. Cases from nine circuits were consolidated in the Eighth Circuit, and on April 4, 2024, the SEC itself voluntarily stayed the rule pending judicial review.⁴

On March 27, 2025, the Commission voted to withdraw its defense of the rule and instructed its lawyers to notify the Eighth Circuit they were no longer authorized to argue in favor of it.¹ The Eighth Circuit is holding the case in abeyance until the SEC either formally rescinds the rule through notice-and-comment rulemaking or renews its defense.

The practical result: no company is required to comply with the 2024 climate rule, and no compliance deadline is running. The rule has not been formally rescinded, so it technically remains on the books, but it carries no legal force while stayed.

What the Stayed Rule Would Require if Revived

Because the rule remains on the books and could return in some form through a new rulemaking, it is worth knowing what it demanded. The requirements below reflect the rule as adopted; any revived version could differ.

Governance and Risk Management

The rule required disclosure of board oversight of climate-related risks and management’s role in assessing and managing them, along with the internal processes used to identify and respond to those risks and their connection to overall business strategy.⁵ Current Regulation S-K does not mandate governance disclosures tied specifically to climate.

Greenhouse Gas Emissions

Large accelerated filers and accelerated filers, excluding smaller reporting companies and emerging growth companies, would report Scope 1 and Scope 2 emissions. Scope 1 covers direct emissions from sources the company owns or controls, such as fuel burned in company vehicles or boilers. Scope 2 covers indirect emissions from purchased electricity, steam, or heating.⁶ The final rule dropped the proposed Scope 3 requirement, which would have reached supply chain and end-use emissions.² Smaller reporting companies, emerging growth companies, and non-accelerated filers were exempt from emissions reporting entirely.

Financial Statement Footnotes

Under a new Article 14 of Regulation S-X, audited financial statements would carry a note disclosing costs, expenditures, charges, and losses from severe weather events and other natural conditions, such as hurricanes, flooding, drought, wildfires, extreme temperatures, and sea level rise. A one-percent-of-total and de minimis threshold applied, so only financially significant impacts had to be reported.²

Carbon Offsets and Renewable Energy Credits

Companies using offsets or renewable energy credits as a material part of their climate strategy would disclose the amount of reduction or renewable energy represented, the nature and source of the instruments, the underlying projects and their locations, any verifying registries, and the cost paid. Associated costs would also appear in the financial statement footnotes.²

The rule also introduced mandatory third-party attestation of emissions data, phased in over several years, with limited assurance first and reasonable assurance later for the largest filers. Because the rule is stayed, none of the compliance dates or assurance milestones are running.

Liability for Inaccurate or Missing Disclosures

The stay of the 2024 rule does not soften liability for environmental disclosures under existing law. A misleading annual report is a misleading annual report, and the enforcement machinery is the same whether the misleading piece involves climate risk, environmental litigation, or anything else.

Civil Liability and SEC Penalties

Section 18 of the Securities Exchange Act gives investors a private right of action against anyone who makes a false or misleading statement in a document filed with the SEC. An investor who bought or sold in reliance on the misleading statement can sue for damages unless the filer proves it acted in good faith and had no knowledge the statement was false.⁷

The SEC can also seek civil monetary penalties. For a company, per-violation penalties currently range from roughly $118,000 for a basic violation up to approximately $1.18 million when the violation involves fraud and causes substantial investor losses. For individuals, penalties range from about $12,000 to $236,000 per violation on the same tiered basis.⁸ These figures are adjusted for inflation each year.

Criminal Penalties

Willfully making a materially false or misleading statement in a required SEC filing is a federal crime. Under Section 32 of the Securities Exchange Act, an individual convicted of this offense faces up to $5 million in fines and 20 years in prison; a company faces fines up to $25 million.⁹ The federal securities fraud statute separately carries penalties of up to 25 years’ imprisonment for anyone who knowingly executes a scheme to defraud in connection with securities.¹⁰ The SEC’s Division of Enforcement has pursued cases involving misleading environmental and ESG claims and refers cases for criminal prosecution when it finds intentional deception.

Shareholder Class Actions

Beyond government enforcement, inaccurate environmental disclosures frequently draw private securities fraud suits. The theory is familiar: a failure to disclose a material environmental risk artificially inflated the stock price, and when the truth emerged, investors lost money. Class action settlements can dwarf any regulatory fine when the stock drop is large and the affected class is broad.

Safe Harbor for Forward-Looking Statements

Some climate-related disclosures inherently involve predictions: transition plans, emissions targets, scenario analyses. The Private Securities Litigation Reform Act provides a safe harbor for these forward-looking statements. A company is generally not liable for a forward-looking statement as long as it identifies the statement as forward-looking, accompanies it with meaningful cautionary language identifying factors that could cause actual results to differ, and the plaintiff cannot prove the statement was made with actual knowledge that it was false or misleading.¹¹

The safe harbor covers transition plan disclosures, scenario analysis, internal carbon pricing, and climate targets and goals. It does not cover historical facts or data included in GAAP financial statements. The statute imposes no duty to update forward-looking statements after they are made, though a company that lets a materially misleading prediction stand uncorrected can still face liability under the general anti-fraud provisions.¹¹ The protection also depends on actually including the required cautionary language at the time of the original disclosure. A defense built after the fact will not work.

Where the SEC Framework Does Not Reach

Federal securities disclosure is not the only environmental reporting track a U.S. public company may face. The European Union’s Corporate Sustainability Reporting Directive requires companies above certain size thresholds to disclose social and environmental risks and impacts, and U.S. companies with significant European operations may fall within scope.¹² The EU adopted a “stop-the-clock” directive in April 2025 postponing reporting deadlines for companies that would have first reported for fiscal 2025 or 2026, and the timeline for non-EU companies is in flux.

At the state level, at least one state has enacted legislation requiring large companies doing business within its borders to annually disclose Scope 1, 2, and 3 emissions (for companies above $1 billion in revenue) and to publish climate-related financial risk reports (at the $500 million revenue threshold). Rulemaking is still under way, but these programs operate independently of the federal rule. Globally, 37 jurisdictions have taken steps to introduce standards developed by the International Sustainability Standards Board, accounting for roughly 60% of global GDP. The United States has not adopted those standards, but multinational companies may encounter them through foreign subsidiaries or listing requirements.
