Why Half of SEC-Covered Companies Still Face Climate Disclosure Rules After the Rollback

The Securities and Exchange Commission's March 2024 climate disclosure rule is functionally dead at the federal level. The Trump administration moved to eliminate it, and a coalition of Republican state attorneys general, the U.S. Chamber of Commerce, and industry groups sued to block it shortly after adoption (hbs.edu · 2025). For compliance teams that spent 2023 and 2024 building emissions inventories and TCFD-aligned governance frameworks, it would be easy to assume the work no longer matters.

That assumption is wrong. According to Ceres, roughly half of the corporations that would have been covered by the SEC rule will still face disclosure obligations in other jurisdictions (hbs.edu · 2025). The rule-shaped hole at the federal level has been backfilled, piece by piece, by California, the European Union, the United Kingdom, and at least 33 other national regulators.

This post walks through what the SEC rule actually required, what got cut in the final version, and which of those requirements now land on U.S. issuers through the back door of state and foreign law.

What the Final SEC Rule Required

The SEC adopted the final rule on March 6, 2024, in a 3-to-2 vote under then-Chair Gary Gensler (carbonchain.com · 2025). The agency received approximately 16,000 public comments during the rulemaking, a record volume reflecting the political weight of the proposal (sweep.net · 2025).

The adopted version required registrants to file, inside annual reports and registration statements including IPO filings, the following (Deloitte · 2024):

Material Scope 1 (direct) and Scope 2 (purchased electricity and energy) greenhouse gas emissions, for Large Accelerated Filers and Accelerated Filers only.
Governance and board-level oversight of material climate-related risks.
Material impact of climate risks on business strategy, business model, and outlook.
Risk management processes for those risks.
Material climate targets and goals, with material expenditures tied to hitting them (watershed.com · 2024).
Financial statement footnote disclosures covering severe weather events and other natural conditions, triggered at a 1% de minimis threshold of pretax income or total shareholders' equity (Deloitte · 2024).
Roll-forward disclosure of carbon offsets and renewable energy credits if material to meeting stated targets.

Emissions were to be reported in carbon dioxide equivalent, disaggregated by gas type (sweep.net · 2025).

What Got Cut

The proposed rule was notably more aggressive than what the SEC actually adopted. Several concessions narrowed its reach:

Scope 3 was eliminated entirely. Supply-chain and product-use emissions, widely considered the largest component of most corporate carbon footprints, were dropped from the final rule (Deloitte · 2024; sweep.net · 2025).
A materiality threshold was added to Scope 1 and 2 disclosures, letting companies decide which emissions streams rise to investor-relevant status (Deloitte · 2024).
Financial statement disclosures were scaled back from the proposal.
Implementation timelines were extended, with assurance requirements phased in later.
Organizational boundary flexibility was granted, meaning registrants could choose how to draw the perimeter of their Scope 1 and 2 inventories.

The compliance calendar that followed was phased: Large Accelerated Filers were scheduled to begin most disclosures in 2025, Accelerated Filers to begin target-setting and climate-risk disclosures in 2026, LAF GHG reports (based on 2026 data) due in 2027, and Accelerated Filer GHG reports (based on 2028 data) due in 2029 (carbonchain.com · 2025). Smaller Reporting Companies, Emerging Growth Companies, and Non-accelerated Filers had a 2027 start for their scoped-down obligations.

That calendar is no longer operative at the federal level. It still matters, because other regulators have set their clocks to similar cadences.

The Patchwork That Replaced It

Thirty-five nations, including all 27 EU member states, are developing, refining, or implementing climate disclosure requirements for large companies (hbs.edu · 2025). The EU's Corporate Sustainability Reporting Directive and the UK's regime are leading the global trend with rigorous rules that pull in non-EU parents and subsidiaries through revenue and branch thresholds (watershed.com · 2024).

Inside the United States, state action is filling the gap:

California, described by Harvard Business School's Institute for Business in Global Society as the fourth-largest economy on the planet, is moving forward with its Climate Corporate Data Accountability Act and related statutes (hbs.edu · 2025; watershed.com · 2024).
New York, Illinois, New Jersey, and Washington are positioned to follow with their own frameworks (hbs.edu · 2025).

California's statutes, unlike the adopted SEC rule, reach Scope 3. Any U.S. company doing meaningful business in California, or with EU revenue above CSRD thresholds, ends up disclosing the very emissions categories the SEC cut.

What Companies Actually Do Next

Workiva and PwC commissioned a survey of 300 executives at U.S.-based public companies to gauge readiness for the SEC rule. The survey found companies still had substantive work to do across technology, staffing, and investment to be fully prepared (workiva.com · 2026). That work has not become obsolete; it has been redirected.

Harvard Business School Professor Ethan Rouen has noted that many companies are already doing some form of climate reporting, and that the core investor concern with the emerging patchwork is the loss of "reliable, comparable disclosures" that can be benchmarked across sectors (hbs.edu · 2025). Steven Rothstein of Ceres frames the investor view more bluntly: more information leads to better capital allocation decisions (hbs.edu · 2025).

For practitioners, three operating principles follow from the current state of play:

Keep the TCFD-aligned work. The SEC rule was structured as a "TCFD+" filing integrated into the 10-K, built on the 11 core questions the TCFD developed (watershed.com · 2024). CSRD, California's regime, and the UK rules all draw on the same underlying framework. Governance, strategy, risk management, and metrics disclosures port across regimes with modest adjustment.
Do not retire Scope 3 inventories. The SEC dropped Scope 3; California and CSRD did not. Dismantling a Scope 3 methodology now creates rework risk for any company with California nexus or EU-scoped revenue.
Pre-IPO companies should still begin voluntary disclosure. Even private U.S. firms on an IPO path have incentive to build climate disclosure infrastructure early, because investors are likely to request the data as part of eventual registration statements regardless of federal mandate status (watershed.com · 2024).

The Bottom Line

The SEC rule's death at the federal level is a political fact, not a compliance conclusion. The materiality-based Scope 1 and 2 disclosures, governance narratives, and financial statement footnotes the SEC finalized in March 2024 represented a floor, not a ceiling. California set a higher floor. The EU set a higher one still. For the roughly 50% of formerly-covered U.S. issuers with state or foreign exposure, the question has shifted from "are we ready for the SEC rule" to "which regime sets the binding constraint, and does our existing inventory meet it."

Most compliance teams will find the binding constraint is no longer Washington.
