The guidance connects the amended legal scope to reporting ownership, ESRS decisions, evidence, assurance, publication, and digital-format controls. CSRD compliance is a reporting obligation built around the management report and ESRS sustainability statement. The compliance file should first show why the undertaking remains in the current scope after Directive (EU) 2026/470, which applies the amended main threshold from financial years beginning in 2027, then document ESRS disclosures, double materiality, value-chain judgments, evidence, assurance, and electronic reporting. ## Start with CSRD scope and reporting perimeter The original CSRD expanded sustainability reporting beyond the earlier non-financial reporting population. Directive (EU) 2026/470 later narrowed the main Articles 19a and 29a scope from financial years beginning in 2027 to undertakings or parent groups exceeding EUR 450 million net turnover and 1,000 average employees. Preserve earlier category and wave evidence, but use the amended thresholds, exemptions, sector or issuer rules, and national law for the current conclusion. The reporting perimeter cannot be copied from a policy template. ESRS 1 says the sustainability statement is for the same reporting undertaking as the financial statements, and then extends the information to material impacts, risks, and opportunities connected through direct and indirect business relationships in the upstream and downstream value chain. - Record the reporting undertaking, group boundary, consolidation basis, and any parent-reporting exemption relied on. - Separate CSRD legal scope from voluntary sustainability reporting, supplier questionnaires, and internal due-diligence program design. - Check whether Article 8 Taxonomy disclosures are also required because CSRD brings the undertaking within Articles 19a or 29a of the Accounting Directive. - Keep the scope memo linked to the management report owner, financial reporting calendar, and national transposition requirements.

The undertaking must identify impacts, risks, and opportunities, assess impact materiality and financial materiality, and then disclose the ESRS information that is material or otherwise required irrespective of the materiality outcome. A defensible assessment should preserve the criteria used, the stakeholder and source inputs considered, the thresholds applied, and the link from each material impact, risk, or opportunity to the relevant ESRS disclosure requirements. Climate change needs particular care because ESRS requires a detailed explanation if the undertaking concludes that climate change is not material and omits all ESRS E1 disclosures. - Maintain an IRO register with impact, risk, opportunity, value-chain location, affected stakeholder, financial effect, time horizon, and ESRS disclosure mapping. - Distinguish mandatory ESRS 2 general disclosures from topical disclosures that depend on the materiality assessment. - When policies, actions, or targets do not exist for a material matter, disclose that fact instead of inventing a control narrative. - Use the EFRAG datapoint list as a gap-analysis and evidence-organising tool, while keeping ESRS itself as the controlling standard.

The sustainability statement must include material upstream and downstream value-chain information where needed to understand material impacts, risks, and opportunities. Different matters can be material in different parts of the value chain. Where value-chain data is incomplete, the CSRD text requires the undertaking, during the first three years of application of the national measures, to explain the efforts made to obtain the information, why it could not be obtained, and the plans to obtain it in the future. That explanation should be tied to a real data-collection log rather than a boilerplate disclaimer. - List the value-chain segments that are material for each ESRS topic, including upstream suppliers, downstream users, products, services, business relationships, and affected stakeholders where relevant. - Document which figures are measured, estimated, supplier-provided, proxy-based, or unavailable, and why the method is appropriate for the disclosure. - Retain evidence of supplier outreach, data-quality checks, estimation methodology, management review, and unresolved limitations. - Avoid treating value-chain reporting as proof of broader conduct compliance unless the page or report separately supports that claim from appropriate sources. Sources for this answer: - [Commission Delegated Regulation (EU) 2023/2772 adopting ESRS](https://data.europa.eu/eli/reg_del/2023/2772/oj?ref=sorena.io) - Supports the ESRS rule that value-chain information is included for material upstream and downstream impacts, risks, and opportunities, not for every actor automatically. - [Directive (EU) 2022/2464 on corporate sustainability reporting](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32022L2464&ref=sorena.io) - Supports the CSRD rule for explaining unavailable value-chain information, efforts made to obtain it, reasons it could not be obtained, and future plans. - [EFRAG ESRS implementation guidance documents](https://www.efrag.org/en/projects/esrs-implementation-guidance-documents?ref=sorena.io) - Supports using EFRAG IG 2 to structure value-chain judgments and implementation work under ESRS. ## Prepare assurance evidence before publication CSRD compliance includes assurance over sustainability reporting. The amended audit rules require an assurance opinion, initially on a limited-assurance basis, covering compliance with the Directive, the ESRS standards, the process used to identify reported information, the electronic markup requirement, and Article 8 Taxonomy reporting where applicable. The evidence pack should be designed for review before the sustainability statement is drafted. Assurance will be difficult if materiality judgments, value-chain estimates, source systems, controls, and management approvals are kept in separate tools with no stable version history. - Create an assurance index that maps each material ESRS disclosure to source system, data owner, preparer, reviewer, approval date, and evidence location. - Preserve the double-materiality methodology, meeting records, thresholds, stakeholder input, IRO register, and climate non-materiality explanation if used. - For each quantitative datapoint, retain calculation logic, data lineage, estimation basis, reconciliation checks, and management sign-off. - Include the digital tagging review in the assurance timetable because CSRD assurance covers the markup requirement as well as the narrative and numeric reporting.

Digital tagging is therefore part of the compliance design, not a final publishing task. EFRAG's ESRS Set 1 XBRL taxonomy material explains that ESMA defines the tagging rules for digital reporting under ESRS Set 1, with the final rules to be adopted through an amendment to the ESEF Regulation. Until final tagging rules apply, preparers can still make the human-readable sustainability statement easier to digitalise by structuring disclosures around separable ESRS datapoints and avoiding vague narrative blocks. - Assign owners for human-readable disclosure drafting, XBRL taxonomy mapping, extension decisions, validation errors, and final filing evidence. - Align the ESRS datapoint inventory with the sustainability statement outline before drafting long narrative sections. - Keep each tagged fact traceable to the reported sentence, table cell, source datapoint, reporting period, unit, and review evidence. - Use ESMA ESEF guidance for technical controls such as Inline XBRL consistency, extension anchoring, readability of block tags, and unique identifiers for tagged facts.

It should explain what changed since the prior report, which materiality judgments or value-chain estimates are likely to be challenged, which data controls failed or required manual adjustment, and which ESRS disclosures need earlier collection in the next cycle. Do not include EU-wide penalty amounts or enforcement guarantees unless the source material for the relevant Member State supports them. CSRD compliance is implemented through national law and assurance, publication, and filing controls; unsupported penalty figures or generic statements can make the page less accurate. - Retain a final sustainability statement copy, assurance report, management approvals, ESEF validation output, XBRL mapping file, and filing receipt where available. - Track post-filing changes as correction, restatement, methodology improvement, source-system change, or future-period action. - Review whether new EU acts, national transposition measures, EFRAG guidance, ESMA technical materials, or company structure changes affect the next reporting cycle. - Use the published report as the baseline for next-year data ownership, not as a one-time communications document.
