Introduction

Multinational companies now face three sustainability disclosure regimes moving in different directions at once. The United States is pulling back at the federal level while individual states push forward. The European Union is simplifying its reporting rules without abandoning them. Asia Pacific markets are increasingly converging around a single global standard, though notable exceptions remain. For a company operating across all three regions, the practical answer is not to wait for one region to settle before acting. It is to build a single data architecture that can serve every jurisdiction at once.

Key Takeaways

• The SEC has proposed rescinding its federal climate disclosure rule, but California and New York continue to advance state level requirements.
• The EU Omnibus I package cut mandatory ESRS datapoints by roughly 70 percent and raised thresholds under the CSRD (Corporate Sustainability Reporting Directive), but the reporting regime itself remains in place.
• More than 21 jurisdictions have made ISSB (International Sustainability Standards Board) standards mandatory, creating a global baseline that increasingly rivals the EU and US frameworks.
• Institutional investors and multinational supply chain buyers are enforcing disclosure expectations independent of what regulators formally require.
• A centralized ESG data platform mapped to multiple frameworks has become the standard approach to managing this complexity.

What Is Happening to the SEC’s Climate Disclosure Rule in 2026?

On May 29, 2026, the SEC proposed to rescind its 2024 climate related disclosure rule in its entirety, arguing the rule exceeded the Commission’s statutory authority under the Securities Act and Exchange Act. The rule had been finalized in March 2024, stayed following litigation, and held in abeyance by the Eighth Circuit while the Commission reconsidered it through notice and comment rulemaking.

This proposal is not a final repeal. The rescission is subject to a 60 day public comment period ending August 3, 2026, followed by a commission vote before it can take effect. Legal analysts tracking the process expect a final rescission is unlikely before late 2026 or early 2027. In the meantime, the rule remains stayed and unenforced, but the broader disclosure landscape it was meant to standardize has not disappeared. State laws, international regimes, and voluntary standards continue to expand around it.

California and New York: State Climate Disclosure Laws Filling the Federal Gap

While federal climate disclosure loses momentum in Washington, state legislatures are moving the opposite direction. California’s SB 253 and SB 261 remain active, requiring companies with more than 1 billion dollars in revenue doing business in the state to report Scope 1 and Scope 2 emissions, with Scope 3 reporting following in 2027.

New York is close behind. The Climate Corporate Data Accountability Act, introduced as Senate Bill 9072A, passed the New York State Senate in February 2026 and is currently before the Assembly Codes Committee. If enacted, it would apply to companies with more than 1 billion dollars in annual revenue doing business in New York, requiring Scope 1 and 2 disclosures beginning in 2028 and Scope 3 disclosures beginning in 2029, with mandatory third party assurance built in from the start.

New York is not alone. Illinois, Colorado, and New Jersey have introduced comparable legislation, and each new bill borrows heavily from California’s framework. For a multinational company, this means the absence of a federal rule does not remove the compliance burden. It relocates it to the state level, where thresholds and timelines vary but the underlying data requirements look increasingly alike.

What Changed Under the EU Omnibus I Simplification Package?

The European Union took a different path. Rather than rescinding its sustainability reporting regime, it simplified it. The Omnibus I Amendment Directive entered into force on March 18, 2026, following adoption by the Parliament and Council in February.

The most significant change is scope. CSRD reporting is now required only for EU companies with more than 1,000 employees and net annual turnover exceeding 450 million euros. The turnover threshold for non EU companies was raised to the same 450 million euro figure, generated within the EU specifically. This shift moves thousands of mid sized companies out of mandatory scope entirely.

The reporting content itself was also trimmed substantially. Mandatory datapoints under the European Sustainability Reporting Standards were reduced from 1,073 to roughly 320, a cut of about 70 percent, with added flexibility for undue cost or effort exemptions. Assurance requirements were capped at a limited assurance standard rather than progressing toward reasonable assurance, and sector specific reporting standards were removed pending future guidance.

CSRD and CSDDD Timelines After Omnibus: What Companies Must Track Now

Companies already reporting under CSRD for fiscal year 2024, commonly called Wave 1 companies, that fall outside the new thresholds are exempted from reporting for fiscal years 2025 and 2026, subject to how individual member states transpose the directive. Member states have until March 19, 2027 to transpose the CSRD changes into national law, and until July 26, 2028 for changes under the CSDDD (Corporate Sustainability Due Diligence Directive).

For companies still in scope, the practical effect is a lighter reporting burden delivered on a similar timeline to what was originally planned. For companies that fall out of scope, customer driven due diligence requests from larger EU trading partners often continue regardless of the formal legal threshold. The exemption changes who must report directly, not who is asked to provide data.

Which Countries Now Require ISSB Aligned Sustainability Disclosure?

Outside the US and EU, a third and increasingly dominant pattern has emerged. More than 21 jurisdictions have made the International Sustainability Standards Board’s IFRS S1 and S2 standards mandatory or are in active phase in, including Australia, Singapore, Japan, the United Kingdom, Malaysia, Hong Kong, South Korea, Brazil, and several African markets.

This convergence matters for a multinational disclosure strategy because ISSB alignment increasingly satisfies overlapping requirements in other regimes. A company that builds its data collection around ISSB’s climate focused framework is rarely doing wasted work, since IFRS S2 already incorporates the recommendations of the TCFD (Task Force on Climate related Financial Disclosures), which underpin much of the EU and voluntary reporting landscape as well.

Australia, Singapore, and Japan: Three Different ISSB Implementation Models

Australia adopted AASB S2, its local implementation of IFRS S2, with an effective date of December 31, 2024. Reporting is phased by company size, with large companies reporting from January 1, 2025, medium sized companies from July 1, 2026, and smaller companies from July 1, 2027.

Singapore moved faster on enforcement. The Singapore Exchange required climate reporting on a comply or explain basis starting in 2024 for all listed companies, then removed the explain option for large cap issuers beginning in fiscal year 2025, making ISSB aligned climate disclosure effectively mandatory for the largest listed businesses.

Japan’s Sustainability Standards Board finalized its own ISSB aligned standards in March 2025. These become mandatory for Prime Market listed companies with market capitalization above 3 trillion yen for fiscal years beginning April 2026, with the scope expanding to companies above 1 trillion yen from April 2027.

Two notable exceptions complicate the convergence story. Canada’s Sustainability Standards Board has issued exposure drafts based on ISSB standards, but had not confirmed a mandatory adoption timeline as of early 2026. China is heading in a different direction altogether, introducing a 2026 disclosure guidance revision built on a double materiality approach that aligns more closely with the EU’s ESRS than with ISSB’s investor focused financial materiality model.

How Do US, EU, and APAC Disclosure Requirements Compare in 2026?

Despite their different starting points, the three regions share one point of convergence: Scope 1 and Scope 2 emissions reporting has become a near universal baseline expectation for large companies. Where they diverge is in materiality approach, assurance rigor, and enforcement posture.

The US state model is single materiality and revenue threshold driven, with assurance requirements building gradually over time. The EU model uses double materiality, weighing both financial impact and impact on people and the environment, with assurance capped at a limited standard following the Omnibus changes. The ISSB model used across most of Asia Pacific applies single, investor focused materiality similar to the US approach, but with faster movement toward mandatory status and less dependence on any single legislature.

For a reporting team, this means a single global dataset can usually satisfy the baseline emissions requirements across all three regions, but materiality framing, assurance level, and disclosure format still need to be tailored to each jurisdiction’s specific rules.

Why Are Companies Still Disclosing Even as US Federal Rules Roll Back?

Regulatory retreat at the federal level has not reduced disclosure pressure from other directions. Institutional investors holding meaningful equity stakes in large US companies, including major index funds and ESG screened funds, increasingly require alignment with voluntary frameworks such as the GRI (Global Reporting Initiative), SASB (Sustainability Accounting Standards Board), and ISSB as a condition of continued investment. This creates a practical disclosure expectation that persists even where no legal mandate exists.

Supply chains apply similar pressure from a different angle. Large retailers, financial institutions, and multinational buyers are embedding ESG data requirements directly into supplier contracts, pushing disclosure obligations down to companies of every size regardless of their own regulatory status. For many mid sized suppliers, a customer’s procurement questionnaire has become a more immediate driver of disclosure than any government rule.

How Should Multinational Companies Structure ESG Reporting Across Jurisdictions?

The most costly mistake companies make in this environment is building a separate reporting process for every regulation and every region. Each new framework then requires its own data collection effort, its own internal owner, and its own audit trail, multiplying cost without improving data quality.

A more resilient approach centralizes raw Scope 1, 2, and 3 data collection once, then maps that single dataset to each required output, whether that is California’s SB 253, New York’s pending CCDAA, the EU’s CSRD, or ISSB aligned reporting in Australia, Singapore, or Japan. This reduces duplication, shortens reporting cycles, and gives a company a single source of truth to defend during an audit or assurance review, regardless of which regulator or customer is asking.

Five Steps to Prepare Your Reporting Strategy for 2026 and Beyond

Executive teams managing multi jurisdiction reporting should treat the following as a working checklist rather than a one time project.

• Map every jurisdiction where the company does business or has qualifying revenue, and identify which disclosure rules currently apply or are pending.
• Identify the strictest applicable standard across those jurisdictions and use it as the internal reporting baseline, since it is easier to scale down than to retrofit upward.
• Centralize Scope 1, 2, and 3 data collection in a single platform rather than maintaining separate spreadsheets or processes per region.
• Build assurance readiness ahead of formal mandates, since limited assurance requirements today often signal reasonable assurance requirements tomorrow.
• Treat investor and supplier data requests as leading indicators of future regulation, not optional extras, and respond to them with the same rigor applied to legal filings.

Conclusion

Regulatory fragmentation across the US, EU, and Asia Pacific is not a temporary condition to wait out. It is the operating environment multinational companies will report within for the foreseeable future. Companies that treat each jurisdiction as a separate compliance project will continue rebuilding their reporting systems every time a rule changes. Companies that build one centralized, audit ready dataset now will be positioned to meet whatever comes next, wherever it comes from.
