EU sustainability reporting looks very different in 2026 than it did when the Corporate Sustainability Reporting Directive (CSRD) was adopted. Two major simplification measures, the Stop-the-Clock Directive and the Omnibus I package, have reshaped who reports, when, and on what basis. This guide lays out the current state of the regime, with the official references and dates, so you can see exactly where things stand.
Every regulation, reference, and date below is drawn from Obsidian's own verified regulatory dataset for the EU jurisdiction, the same tier-0 data our MCP server serves to AI assistants. Each record was last verified between April and June 2026.
The core framework: CSRD and ESRS
CSRD, Directive (EU) 2022/2464 (OJ L 322, 16.12.2022), entered into force on 5 January 2023 and replaced the older Non-Financial Reporting Directive (NFRD, Directive 2014/95/EU, now repealed). It vastly expanded both the number of companies in scope and the depth of disclosure required.
The "what to report" is defined by the European Sustainability Reporting Standards (ESRS), set out in Commission Delegated Regulation (EU) 2023/2772, in force since 1 January 2024, with a targeted amendment ("quick fix") via Delegated Regulation (EU) 2025/1416 in late 2025. Reporting follows the principle of double materiality: companies disclose both how sustainability issues affect them and how they affect the world.
Sitting alongside CSRD are the EU Taxonomy Regulation (EU) 2020/852, which classifies environmentally sustainable activities, and the Corporate Sustainability Due Diligence Directive (CS3D, Directive (EU) 2024/1760), which adds human-rights and environmental due-diligence obligations across the value chain.
What changed: Stop-the-Clock and Omnibus I
This is the part most teams are trying to get straight. In response to concerns about burden and sequencing, the EU introduced two measures:
- Stop-the-Clock Directive (EU) 2025/794 (in force 17 April 2025) postponed the reporting start dates for CSRD Wave 2 and Wave 3 companies, and pushed back the CS3D timeline, to buy time for the substantive simplification that followed.
- Omnibus I Directive (EU) 2026/470 (approved by the European Parliament on 16 December 2025, in force 18 March 2026) amended both CSRD and CS3D, narrowing scope and easing requirements. Member States have until 19 March 2027 to transpose the CSRD changes; the CS3D transposition deadline moved to 26 July 2028, with application from 26 July 2029.
The practical effect: fewer companies are pulled in earlier than expected, the heaviest obligations land later, and the exact wave you fall into now depends on the amended thresholds rather than the original 2022 text. This is precisely the kind of distinction, draft versus in force, original deadline versus amended deadline, that a general AI model gets wrong, because it cannot see which version is current.

The wider sustainable-finance picture
Two more 2024 instruments round out the regime. The VSME standard, a voluntary sustainability reporting standard for non-listed SMEs, was delivered by EFRAG to the Commission on 17 December 2024 and endorsed on 30 July 2025, giving smaller companies a proportionate option. And Regulation (EU) 2024/3005 on the transparency of ESG rating activities becomes applicable on 2 July 2026, bringing ESG ratings providers under supervision.

The CSRD regime is a moving target: a 2022 directive, amended by a 2025 delay, then a 2026 simplification, with companion instruments on their own clocks. A general-purpose model trained before these changes will confidently describe the original 2022 rules as if they were still current. As we explain in why AI hallucinates on regulatory questions, the fix is not a smarter model, it is giving the model access to verified, dated, versioned data, the approach behind agentic regulatory intelligence.
The takeaway
In 2026, "what does CSRD require" has no single answer without knowing the amended scope and the wave a company falls into. The regime is now CSRD plus ESRS plus Taxonomy plus CS3D, as modified by Stop-the-Clock and Omnibus I. Tracking it reliably, by hand or by AI, depends on data that knows which version is in force today. That is exactly what a verified regulatory layer provides.
