Introduction

The Omnibus I Directive, which entered into force on March 18, 2026, reduced the number of non-EU companies subject to CSRD obligations by approximately 88% — from roughly 10,000 to 1,200. For those that remain in scope under the revised Article 40a threshold, the FY2028 reporting deadline is firm and data infrastructure must be operational well before that date. This article provides the definitive post-Omnibus scoping test, country-by-country exposure estimates, and the compliance roadmap every non-EU finance and sustainability leader needs today.

Key Takeaways

• The Omnibus I Directive cut non-EU CSRD scope by approximately 88% — from roughly 10,000 companies to an estimated 1,200 worldwide, per EFRAG’s June 2026 assessment.
• The revised Article 40a trigger requires €450 million in EU net turnover at group level plus a qualifying EU subsidiary or branch exceeding €200 million — with no headcount requirement.
• Approximately 350–450 US companies and 150–200 UK companies remain in scope, alongside Switzerland and Japan combined at 100–150 and all other jurisdictions at 30–80, per EFRAG’s June 2026 estimates.
• First mandatory Article 40a reports cover FY2028, with filing due in 2029 — this timeline applies specifically to non-EU parent companies on the Article 40a track; in-scope EU companies report from FY2027 on a separate schedule.
• Non-EU parents face a strategic choice between NESRS and full ESRS — a decision with direct consequences for whether EU subsidiaries must file standalone sustainability reports.
• EFRAG’s N-ESRS public consultation opens mid-July 2026 — the primary window to influence the standards governing FY2028 disclosures.
• The value chain cascade remains active — even out-of-scope suppliers face ESG data requests from in-scope customers, now capped by the new voluntary SME standard.

What Is CSRD Article 40a and Why Does It Apply to Non-EU Companies?

The Extraterritorial Reach of the CSRD: How EU Law Applies Beyond EU Borders

The CSRD’s core rationale is competitive neutrality: if only EU-headquartered companies were required to publish verified sustainability disclosures, non-EU multinationals would face a lower compliance cost in the same markets. Article 40a operationalizes this by requiring non-EU parent companies with significant EU revenue to produce a group-level sustainability report covering their global operations — not just their EU activities. A Japanese manufacturer with €500 million in EU revenue and a qualifying German subsidiary must report Scope 1, Scope 2, and Scope 3 emissions for its entire worldwide group.

The “Wait-and-See” Argument — and Why It Is Risky

The U.S. Chamber of Commerce has formally characterized Article 40a as regulatory overreach, and both Norges Bank Investment Management and BlackRock have flagged tensions between CSRD’s extraterritorial scope and other jurisdictions’ legal frameworks. This opposition is legitimate — and the Omnibus did respond to it by raising the thresholds substantially. However, the Article 40a mechanism itself was retained, not repealed. Companies that have deferred preparation on the assumption that further political pressure will eliminate the obligation are now 30 months from the FY2028 start date with no data infrastructure in place. The asymmetry is stark: a company that prepares and finds the regulation further simplified loses some months of effort; a company that waits and finds it unchanged faces a compressed 12-month implementation sprint against an audit-ready standard.

How the Omnibus I Directive Changed the Scope: From 10,000 to 1,200 Companies

Under the original CSRD, non-EU companies fell in scope at €150 million in EU revenue with a €40 million EU subsidiary or branch. The Omnibus I Directive (EU) 2026/470, published February 26, 2026, raised both thresholds — to €450 million at group level and €200 million for the qualifying subsidiary or branch. According to EFRAG’s June 2026 assessment, this reduces non-EU companies in scope by approximately 88%, to roughly 1,200 globally.

Which Non-EU Companies Remain In Scope After the Omnibus Simplification?

The Three-Part Article 40a Scoping Test: €450M, €200M, and No Headcount Requirement

Article 40a applies when three conditions are met simultaneously: the non-EU ultimate parent generates EU net turnover exceeding €450 million in each of the last two consecutive financial years; it operates either a qualifying EU subsidiary or EU branch with net turnover exceeding €200 million in the prior financial year; and, in the case of a subsidiary, it qualifies as a large EU undertaking or listed SME under the amended Accounting Directive. Critically, there is no headcount requirement for non-EU parents — unlike the 1,000-employee threshold applied to EU undertakings. Capital-intensive companies in financial services, technology, and energy trading cannot use a lean headcount to argue themselves out of scope.

Country Breakdown: Estimated In-Scope Companies by Jurisdiction

EFRAG’s June 2026 analysis estimates that the United States accounts for the largest single share at 350–450 companies, followed by the UK at 150–200, Switzerland and Japan combined at 100–150, and all other jurisdictions at 30–80. For Japanese companies in particular, many of the largest manufacturers, trading companies, and financial institutions clear the €450 million EU revenue threshold through established European subsidiaries — and unlike US peers, most have had limited direct engagement in the Brussels policy debate to date.

What Must Non-EU Parent Companies Actually Report Under CSRD?

Impact-Only Materiality: What Non-EU Parents Must Disclose Under NESRS

EU undertakings must satisfy double materiality — disclosing both financial risks from sustainability factors and the company’s own impacts on people and the environment. The draft NESRS, as currently designed by EFRAG, would subject non-EU Article 40a filers to impact materiality only: no double materiality assessment, with datapoints related to sustainability-linked financial risks and opportunities removed from the standard. This distinction is the expected direction of the NESRS, confirmed in EFRAG’s published exposure drafts — however, the NESRS has not yet been formally adopted, and the final delegated act is not expected until 2027. Companies should treat the impact-only scope as the working design basis while monitoring EFRAG’s mid-July 2026 consultation for any changes. In practice, Scope 1, Scope 2, and Scope 3 emissions remain central disclosures regardless of which materiality framework applies, and climate-related impacts are expected to be reported on a global basis.

The Value Chain Cap: What In-Scope Companies Can and Cannot Request from Suppliers

The Omnibus introduced a value chain cap: in-scope companies cannot request sustainability data from value chain partners with fewer than 1,000 employees that exceeds the content of the voluntary SME standard (VSME). Three carve-outs apply — where required by other legal obligations, where data is already publicly available, or where a specific proportionate need can be demonstrated. For Scope 3 collection programs, this requires mapping which Tier 1 and Tier 2 suppliers fall below the threshold and structuring data requests accordingly.

Should Your Company Report Under NESRS or ESRS? The Strategic Choice Explained

Reporting Under NESRS: Lighter Obligations, Standalone Subsidiary Risk

NESRS is the default pathway for Article 40a filers — impact-only, no double materiality assessment, no EU Taxonomy obligation, PDF format accepted. However, filing under NESRS does not exempt qualifying EU subsidiaries from their own standalone CSRD reports under Articles 19a or 29a. A non-EU group with multiple large EU subsidiaries may therefore end up with both a parent-level NESRS report and separate subsidiary-level ESRS reports — a parallel compliance burden that negates some of the simplification benefit.

Voluntarily Adopting ESRS: The Subsidiary Exemption Advantage

A non-EU parent may instead voluntarily produce a group-level consolidated sustainability statement under the full ESRS. Doing so activates the subsidiary exemption: qualifying EU subsidiaries included in the parent’s consolidated ESRS report are relieved of their own standalone filing obligations. For groups with several large EU subsidiaries, the voluntary ESRS pathway may reduce total reporting volume despite the higher parent-level disclosure requirements. EFRAG’s revised ESRS 2.0 reduces mandatory datapoints by over 60% compared to the original framework, and enhanced interoperability with ISSB IFRS S1 and S2 narrows the incremental distance for companies already aligned to those standards.

What Are the CSRD Compliance Deadlines for Non-EU Parent Companies?

Key Milestones from July 2026 to the FY2028 Filing Deadline

Building Your Scope 1, 2, and 3 Data Foundation: Why 2026 Is the Year to Act

FY2028 data collection begins on January 1, 2028 — meaning reporting mechanisms across all operational sites, subsidiaries, and material value chain partners must be in place before that date. Establishing a compliant Scope 1, 2, and 3 data program for a large multinational typically requires 12 to 18 months of implementation. Companies beginning in 2026 enter 2028 with a tested, audit-ready system. Those waiting for the NESRS to be formally adopted in 2027 face a compressed sprint with no margin for error — against a mandatory third-party assurance requirement that demands documented audit trails and traceable source data for every material disclosure.

Risks and Penalties for Non-Compliance

The CSRD delegates penalty-setting to individual EU member states, which must transpose the Omnibus I Directive by March 19, 2027. Financial penalties will therefore vary by jurisdiction but must be effective, proportionate, and dissuasive under EU law. Beyond fines, three consequential risks apply: EU subsidiaries of a non-compliant parent may be required to file standalone sustainability reports, increasing aggregate compliance burden; institutional investors operating in EU capital markets are increasingly requiring CSRD-aligned disclosures as part of their own SFDR obligations, exposing non-compliant companies to exclusion from European portfolios and bond issuances; and non-compliance may result in exclusion from EU public procurement processes.

What’s Next: The N-ESRS Consultation and the Path to Final Standards

EFRAG’s mid-July 2026 N-ESRS public consultation is the primary opportunity for non-EU companies and their trade associations to influence the standards that will govern FY2028 disclosures. EFRAG has confirmed the NESRS will be based on a simplified version of ESRS 2.0 calibrated to Article 40a’s impact-only scope. Following the consultation, EFRAG targets delivery of its final technical advice to the Commission by end of January 2027, with the Commission adopting the NESRS delegated act in 2027. Non-EU companies should treat the July 2026 consultation as a board-level governance priority.
