What is SEC Climate Rule?

Status, September 2026: The SEC's climate disclosure rules never took effect. The SEC stayed them in April 2024, voted in March 2025 to stop defending them in court, and in 2026 proposed rescinding them entirely (comments closed August 3, 2026). The Eighth Circuit is holding the litigation in abeyance. The rest of this page describes the rules as adopted. Source: SEC.

What is SEC Climate Rule?

The SEC's climate-related disclosure rule, formally titled "The Enhancement and Standardization of Climate-Related Disclosures for Investors," was adopted by the Securities and Exchange Commission in March 2024 after two years of public comment on a 2022 proposal. The final rule requires public companies to disclose material climate-related risks, governance and risk management processes, climate-related financial statement effects, GHG emissions (material Scope 1 and 2 emissions for large accelerated and accelerated filers), and climate targets and transition plans when material. The rule applies within SEC registration statements and annual reports (Forms 10-K and 20-F), embedding climate disclosure within existing securities reporting rather than creating a separate reporting channel.

Why It Matters

The SEC climate rule was the first time the United States federal securities regulator adopted standardized climate disclosure requirements for public companies. While the EU moved first with the CSRD and various countries adopted TCFD or ISSB requirements, the U.S. securities market's size (listed domestic companies worth about $69 trillion in 2025, according to the World Bank) makes SEC action globally consequential. Non-U.S. companies listed on U.S. exchanges through ADRs or dual listings also fall within scope, extending the rule's reach internationally.

The rule faced immediate legal challenge. A coalition of states and industry groups filed suit in the Eighth Circuit Court of Appeals, and the SEC voluntarily stayed the rule in April 2024 pending judicial review. In March 2025 the SEC voted to stop defending the rule, and the Eighth Circuit is holding the case in abeyance. On May 29, 2026, the SEC proposed rescinding the rule entirely; the proposal was published in the Federal Register on June 3, 2026, and comments were due August 3, 2026. None of the rule's compliance dates took effect. Investor demand for climate data persists regardless, and existing SEC disclosure rules, as explained in the SEC's 2010 interpretive guidance, still require disclosure of material climate risks.

The final rule was significantly narrowed from the 2022 proposal. Most notably, the SEC dropped mandatory Scope 3 emissions disclosure—the most controversial element—and limited Scope 1 and 2 disclosure to large accelerated filers (public float of $700 million or more) and accelerated filers, only where the emissions are material and subject to third-party attestation. The rule also raised the materiality threshold, requiring climate risk disclosure only when risks are "material" under established securities law standards rather than requiring disclosure of all identified climate risks. These concessions reflected political and legal pragmatism, but the rule would still have substantially expanded required climate disclosure for U.S. public companies.

For companies already reporting under TCFD, ISSB, or CSRD, the SEC rule would have added a specific U.S. compliance dimension. The rule's requirements overlap significantly with these frameworks but include SEC-specific elements: climate-related financial statement disclosures (a footnote requirement unique to the SEC rule), specific quantitative thresholds for capitalized costs and expenditures from severe weather events, and integration with existing MD&A and risk factor disclosure requirements. Because the rule never took effect, none of these SEC-specific elements apply; U.S. emissions reporting obligations now come mainly from California's SB 253, whose first Scope 1 and 2 reports are due November 10, 2026.

How It Works / Key Components

The rule's requirements fall into four categories. First, governance and risk management: companies must describe board oversight of climate-related risks, management's role in assessment and management, and how climate risk management integrates with overall risk management processes. These requirements align closely with TCFD and ISSB governance pillars.

Second, climate-related risks: companies must disclose material climate-related risks, including both physical risks (acute and chronic) and transition risks (regulatory, technological, market, and reputational). For each material risk, companies describe its nature, whether it's a current or forward-looking risk, its actual or potential effects on strategy, business model, and outlook, and how it has affected or is likely to affect financial performance. Companies must also describe activities to mitigate or adapt to material risks, including transition plans and scenario analysis when used.

Third, GHG emissions: large accelerated filers and accelerated filers must disclose material Scope 1 and Scope 2 emissions separately, in gross terms excluding any offsets, and describe the methodology used (typically the GHG Protocol). These disclosures require third-party attestation: limited assurance from fiscal years beginning in 2029 for large accelerated filers and 2031 for accelerated filers, with large accelerated filers moving to reasonable assurance from fiscal years beginning in 2033. Smaller reporting companies, emerging growth companies and non-accelerated filers are exempt from emissions disclosure under the final rule's scaled approach.

Fourth, financial statement disclosures: the rule requires a financial statement footnote disclosing the capitalized costs, expenditures, charges, and losses incurred from severe weather events and other natural conditions, as well as costs of carbon offsets and renewable energy credits used as a material component of plans to meet disclosed climate targets. This footnote requirement—subject to audit by the company's financial statement auditor—represents the most novel element of the SEC rule and creates a direct link between climate events and audited financial data.

Council Fire's Approach

Council Fire helps U.S.-listed companies and foreign private issuers meet the climate disclosure expectations that remain after the SEC rule's stay by assessing materiality of climate-related risks under SEC standards, building GHG inventory capabilities that meet attestation requirements, developing financial statement footnote processes for severe weather impacts, and integrating SEC-specific requirements into global climate reporting programs that also satisfy ISSB, CSRD, and CDP obligations.

Frequently Asked Questions

Is the SEC climate rule currently in effect?

No. The SEC stayed the rule in April 2024, before any compliance date arrived, pending legal challenges consolidated in the Eighth Circuit Court of Appeals. In March 2025 the SEC voted to stop defending it, and the court is holding the case in abeyance. On May 29, 2026, the SEC proposed rescinding the rule entirely; the proposal was published in the Federal Register on June 3, 2026, and comments were due August 3, 2026. The rule stays on the books until a final rescission, but none of its requirements apply. Companies still face climate disclosure demands from other sources: existing SEC disclosure rules (as explained in the SEC's 2010 guidance) require disclosure of material climate risks, California's SB 253 requires large companies doing business in the state to report Scope 1 and 2 emissions (first reports due November 10, 2026), the CSRD and ISSB-based rules apply in other markets, and investors continue to ask for climate data.

How does the SEC rule compare to the CSRD and ISSB standards?

As adopted, the SEC rule was narrower in scope than both. It covered only climate (not broader ESG), required only Scope 1 and 2 emissions (no mandatory Scope 3), applied single materiality under U.S. securities law standards, and applied only to SEC registrants. CSRD/ESRS covers all ESG topics with double materiality; after the EU's 2026 Omnibus I changes it applies to companies with more than 1,000 employees and more than €450 million in net turnover. ISSB covers all sustainability topics material to enterprise value. The SEC rule would also have required audited financial statement footnotes on climate impacts and specific severe weather cost disclosures, requirements not found in CSRD or ISSB. Because the SEC rule never took effect, those footnotes are not required; companies subject to the CSRD, ISSB-based rules or California's laws still need an integrated approach that addresses each regime's unique elements.

Do I need third-party assurance for my emissions data under the SEC rule?

No. The rule's attestation requirements never took effect. As adopted, large accelerated filers (public float of $700 million or more) would have needed limited assurance over Scope 1 and Scope 2 emissions from fiscal years beginning in 2029, moving to reasonable assurance from 2033, and accelerated filers limited assurance from 2031. The attestation provider would have had to be independent and expert in GHG emissions. Non-accelerated filers, smaller reporting companies and emerging growth companies were exempt. Assurance obligations now come from other rules: California's SB 253 requires limited assurance of Scope 1 and 2 emissions from 2027 and reasonable assurance from 2030, and the CSRD requires limited assurance for companies in scope. Building assurance-ready emissions data processes (internal controls, documentation, and data governance that can withstand external verification) still pays off for companies subject to those rules.
