Five actions Reporting Teams Must Take Before the SEC Climate Rule Is Decided

Five actions Reporting Teams Must Take Before the SEC Climate Rule Is Decided

The SEC has not finalized a rescission of its climate disclosure rules, but it has formally proposed one. On May 29, 2026, the Commission issued Release No. 33-11421 proposing to rescind the 2024 climate rules, with the public comment period closing August 3, 2026. Since the 2024 rules were stayed shortly after adoption and never took effect, registrants currently face no active enforcement of the line-item mandates, though the underlying materiality and antifraud obligations remain fully in force.

TL;DR:

  • The SEC's proposed rescission of the 2024 climate disclosure rules is still under review, and no final decision has been made.
  • The 2024 rules included specific line items, thresholds, and phased assurance requirements, which would be removed if rescinded.
  • Companies should focus on materiality-based disclosures and maintain existing data infrastructure for ongoing and voluntary climate reporting.
  • Preparers need to assess material climate risks independently of the pending rule and invest in strengthening data controls and assurance readiness.
  • Legal challenges remain pending, but a final rescission order would likely render the litigation moot, while a narrowed rule could revive it.

Where we are now: the SEC's rescission proposal and the timeline practitioners must track

The rescission proposal moved through the standard notice-and-comment process. The SEC published its proposing release on May 29, 2026, the Federal Register carried the formal notice on June 3, 2026, and the comment window closed August 3, 2026. That structure matters because a proposed rescission is not self-executing: the Commission must review comments, complete an economic analysis, and then decide whether to finalize the rescission, modify its scope, or withdraw the proposal entirely.

For compliance officers, the practical takeaway is that nothing is settled yet. The Commission could still adjust the rule rather than eliminate it outright, and the timeline for a final decision has not been announced.

The sequence so far:

  • March 2024: SEC adopts the climate disclosure rule (Release No. 33-11275).
  • April 4, 2024: Commission stays the rule pending judicial review.
  • March 27, 2025: SEC ends its defense of the rule in litigation.
  • May 29, 2026: SEC proposes rescission (Release No. 33-11421).
  • August 3, 2026: Comment period closes.

What the 2024 final rule would have required

The rule the SEC adopted in March 2024 built new disclosure architecture into Regulation S-K and Regulation S-X. Registrants would have had to identify material climate-related risks, describe board and management oversight of those risks, and disclose any transition plans, scenario analysis, or internal carbon pricing used in decision-making. Companies with material targets or goals related to climate would also have had to describe progress toward them.

Two provisions drew the most operational concern. The first was the severe-weather financial-effects disclosure, which required companies to quantify the financial statement impact of severe weather events once losses crossed a one percent threshold of relevant line items, a de minimis test that preparers said was difficult to build reliable controls around. The second was the phased Scope 1 and Scope 2 greenhouse gas disclosure requirement for larger registrants, which came paired with a phased attestation schedule moving from limited assurance to reasonable assurance over time.

The rule's phased attestation structure, tying assurance levels to filer size and reporting year under Release No. 33-11275, was the primary driver of early assurance-market preparation, since limited assurance engagements (LAF) and reasonable assurance engagements (AF) require different levels of audit evidence and cost.

Phased emissions assurance evidence pathway

The Commission's stated rationale centers on statutory authority and materiality. In its proposing release and accompanying statements, the SEC argues the 2024 rule extended beyond what federal securities law requires and that disclosure mandates should track information a reasonable investor would consider decision-useful, not prescriptive line items tied to specific thresholds.

Industry and legal commentary submitted during the comment period reinforced that position. A joint comment letter from Financial Executives International and CCR argued that the rule's compliance costs were disproportionate to investor benefit, that it duplicated obligations already covered by existing SEC disclosure and antifraud rules, and that building SOX-compliant controls around a one percent severe-weather threshold created outsized operational burden relative to the informational payoff.

Not every voice supports rescission. Investor advocates and some institutional asset managers have argued that removing the rule sacrifices comparability across companies and industries, at a moment when demand for consistent climate data across portfolios has been rising. The Commission's proposal acknowledges this tension but concludes the costs outweigh the benefits as currently structured.

Recurring themes from the comment record:

  • Compliance costs and control-building burden were cited as disproportionate to investor benefit.
  • Overlap with other disclosure regimes, including voluntary ISSB and IFRS S1/S2 frameworks, was flagged as duplicative.
  • Comparability advocates warned that rescission removes a common baseline investors had begun to expect.

Practical implications for registrants and financial reporting

If finalized, rescission would remove the 2024 rule's prescriptive mandates: the specific line items, the one percent severe-weather threshold, and the phased attestation schedule. It would not remove a registrant's existing duty to disclose material information, including material climate risks, under Regulation S-K's general materiality standard and the antifraud provisions of the securities laws. Materiality-based disclosure obligations predate the 2024 rule and survive independent of its fate.

For finance, legal, and sustainability teams, three consequences follow:

  1. Implementation programs built around the 2024 timeline should be paused, not abandoned, since the underlying data infrastructure remains useful for materiality-based reporting.
  2. Sunk costs in emissions-tracking systems and control design are not wasted, as this infrastructure supports voluntary frameworks and investor communications regardless of the rule's outcome.
  3. Auditors and assurance providers should be looped in early on any change in scope, since assurance engagements planned around the SEC's phased schedule may need to shift toward voluntary or jurisdiction-specific requirements instead.

Where companies want to preserve consistent investor communication through the uncertainty, aligning voluntary disclosures with the ISSB's IFRS S1 and S2 standards offers a reference point that does not depend on the SEC's final decision.

Pro Tip: Keep a written record distinguishing which disclosures are made because the law requires them and which are voluntary. That distinction protects the company if enforcement posture changes later.

What companies should do now: a short action plan

Regulatory uncertainty is not a reason to freeze. A short list of moves reduces risk under nearly every plausible outcome, from full rescission to a narrowed final rule.

  1. Run a materiality assessment focused on investor decision-usefulness, independent of whether the 2024 line items survive, and document the process for the board.
  2. Brief the board on current status and residual risk, making clear which obligations are settled law and which remain contingent on the rescission proceeding.
  3. Inventory Scope 1 and Scope 2 data sources over the next several months, since data readiness is the single hardest thing to build quickly if requirements return.
  4. Strengthen the control environment around emissions and climate risk data, treating it as financial-reporting-adjacent even where it is not yet formally mandated.
  5. Pilot a limited assurance engagement on material climate metrics where the company already discloses them voluntarily, to build institutional muscle memory ahead of any future requirement.

Pro Tip: Whatever a company discloses voluntarily during this period, state plainly in the filing or report whether it reflects SEC requirements or a voluntary choice. Investors and regulators both read that distinction closely.

Litigation and regulatory triggers: what to monitor

The consolidated legal challenges to the 2024 rule sit with the Eighth Circuit Court of Appeals, which placed the litigation in abeyance on September 12, 2025 after the Commission stopped defending the rule in court on March 27, 2025. That abeyance freezes the case rather than resolving it, and it can be lifted if circumstances change.

Several developments could shift the picture:

  • A final rescission order from the Commission would likely prompt the court to dismiss the underlying litigation as moot.
  • A modified final rule, rather than outright rescission, could revive litigation over the narrower version.
  • A change in Commission composition or priorities could alter the pace or direction of the rulemaking.
  • Targeted rulemaking focused narrowly on materiality standards, separate from the current proposal, remains a possibility worth watching.

Compliance teams should track the SEC newsroom, Federal Register filings, and the Eighth Circuit docket directly rather than relying on secondary summaries, since the next procedural step could arrive with limited advance notice.

Governance priorities while regulatory uncertainty persists

The temptation during a rescission proceeding is to treat climate disclosure as paused work. That reading misses the more durable point: materiality-based disclosure obligations were never contingent on the 2024 rule, and boards that let data infrastructure atrophy now will rebuild it under worse time pressure later, whichever way the rulemaking lands.

The more defensible posture is a materiality-first one, paired with continued, proportionate investment in data systems and staff capability. Finance, audit, and sustainability teams that understand both the SEC's investor-focused materiality standard and international frameworks like IFRS S1 and S2 are positioned to serve either outcome, a narrowed SEC mandate or a voluntary-disclosure environment shaped by global standards. Structured training and certification remain one of the more efficient ways to build that dual fluency across a team without waiting for the rulemaking to conclude.

How ESG Training Institute helps teams prepare for either outcome

Regulatory uncertainty does not lower the bar on skills. Teams still need people who can run a materiality assessment, build defensible Scope 1 and 2 data pipelines, and speak the language auditors use when assurance conversations start. Certifications in ESG and sustainability map directly to those needs rather than to a single rule's fate.

Relevant paths for teams working through this transition include:

  • Mastering IFRS S1 & S2 Sustainability Reporting, for teams aligning voluntary disclosures to the international standard regardless of the SEC's final decision.
  • Certificate in Carbon Accounting, for building the Scope 1 and 2 measurement discipline that assurance providers expect.
  • Certificate in Climate, Sustainability and ESG Assurance, for staff preparing to support or manage limited assurance engagements.
  • Certificate in ESG Governance, for directors and officers who need to brief boards clearly on what is required versus voluntary.

Course details, formats, and enrollment are available on the Institute's certification programs page, with CPD and masterclass options on the CPD hub for teams building capability in stages.

FAQ

What are the new SEC rules for 2026?

There is no new finalized SEC climate rule in 2026. The Commission proposed rescinding the existing 2024 climate disclosure rule in a May 29, 2026 release, and that proposal was still under review after the comment period closed.

What happened to the SEC climate disclosure rule?

The rule was adopted in March 2024 but never took effect. The SEC stayed it in April 2024, stopped defending it in court in March 2025, and proposed formally rescinding it in May 2026, with related litigation held in abeyance at the Eighth Circuit.

What are the latest SEC rules on climate disclosure?

The most current SEC action is the proposed rescission of the 2024 climate disclosure rule, published as Release No. 33-11421. No new mandatory climate rule has replaced the 2024 text, and the rescission itself has not been finalized.

Is ESG reporting still required?

SEC-specific climate disclosure mandates from the 2024 rule are not in effect and may be rescinded, but general materiality and antifraud disclosure obligations still apply to material climate information. Many companies also continue voluntary ESG reporting aligned with frameworks like IFRS S1 and S2, independent of the SEC proceeding.
