EU Omnibus I Directive (EU) 2026/470 — CSRD and CSDDD simplification

Mechanism

The Omnibus I directive is a single legislative instrument amending four existing directives (the Audit Directive 2006/43/EC, the Accounting Directive 2013/34/EU, the CSRD 2022/2464, and the CSDDD 2024/1760). It is the largest single rollback of the EU sustainability-reporting and supply-chain due-diligence framework since those instruments were adopted, and forms the core of the von der Leyen II Commission's "competitiveness simplification" agenda announced February 2025.

Three sets of changes matter for IPTM:

1. CSRD scope narrowed. The original CSRD pulled in roughly 50,000 EU undertakings (large companies, listed SMEs, and non-EU groups with EU subsidiaries or branches above defined turnover). Omnibus I raises the thresholds so that only undertakings with more than 1,000 employees AND more than EUR 450 million net turnover fall in scope — an estimated reduction to roughly 5,000 in-scope groups (about 90% of the original cohort exits). Reasonable-assurance audit obligations are dropped; limited-assurance is retained, with the Commission required to adopt harmonised limited- assurance standards by 1 July 2027.

2. CSDDD scope narrowed and obligations softened. CSDDD is now limited to EU entities with more than 5,000 employees AND more than EUR 1.5 billion turnover, and to non-EU entities with more than EUR 1.5 billion EU turnover. The full obligation to adopt or "put into effect" a climate transition plan is removed. The depth of value-chain due diligence is reduced (focus narrowed toward direct/Tier-1 business partners with risk-based escalation rather than full upstream cascade). The civil- liability regime is softened and member states regain discretion over national-law transposition. The financial-sector value-chain inclusion is dropped.

3. Transposition timeline. CSRD-related amendments must be transposed into national law by 19 March 2027; CSDDD-related amendments by 26 July 2028. This pushes effective in-country enforcement well into 2028-2029 for most member states.

Downstream implications

• The CSDDD was, until this rollback, the most stringent legally-binding

supply-chain due-diligence framework in any major jurisdiction. By scaling back depth-of-cascade obligations and dropping the financial-sector inclusion, Omnibus I reduces compliance pressure on EU-import supply chains rooted in China, India, Vietnam, Bangladesh, Indonesia, Brazil, and the rest of the EM exporter base. The de facto extra-territorial reach of CSDDD shrinks.

• The narrowing of CSRD pushes most mid-cap and smaller listed firms outside

the mandatory ESRS-reporting boundary, which materially reduces ESG-data supply for downstream investors and rating agencies focused on EU coverage. Side effect: the European Sustainability Reporting Standards (ESRS) are themselves under revision in parallel.

• Combined with the EU Industrial Accelerator Act (2026-03-04) and the EU

Clean Industrial Deal (2025-02-26), Omnibus I signals that the Commission is net-relaxing horizontal regulatory burden on EU producers in order to free capacity for the IRA-response industrial-policy build-out. It is the deregulatory leg of the western industrial-policy stack rather than a new subsidy or perimeter mechanism.

• Watch the parallel "Omnibus II" / "Omnibus III" packages that the

Commission has flagged for further sustainability and reporting simplification (taxonomy, ESRS, EUDR alignment) — those will continue the rollback through 2026-2027.

Open questions

• Will member states with stronger existing national mandatory-due-diligence

laws (France's loi de vigilance, Germany's LkSG) "gold-plate" the Omnibus I CSDDD floor, partially undoing the simplification?

• Where the Commission's harmonised limited-assurance standards land

(1 July 2027 deadline) will determine how meaningfully reduced CSRD audit-cost is in practice.

• Is there a pending CJEU challenge from civil-society or member-state

complainants on the Climate Plan deletion vis-à-vis the EU Climate Law (Reg 2021/1119) Article 4? Watch litigation tracker through 2026 H2.
