The linked FAQ modules cover scope, reporting waves, ESRS 1 and ESRS 2, topical ESRS scoping, double materiality, assurance evidence, digital tagging, Article 8 KPIs, listed SME standards, third-country groups, and value chain estimates. The Corporate Sustainability Reporting Directive changes EU sustainability reporting by extending reporting beyond the old non-financial reporting population and requiring companies in scope to report under European Sustainability Reporting Standards. Use this FAQ hub to find the specific answer behind a CSRD decision: entity scope, first reporting year, ESRS datapoint inventory, double materiality, value chain data, assurance, digital filing, or EU Taxonomy Article 8 reporting. ## Browse sub-FAQ modules ### [CSRD Article 40a third-country group reporting FAQ](/artifacts/eu/corporate-sustainability-reporting-directive/faq/third-country-groups.md) FAQ on when CSRD Article 40a applies to third-country groups, which EU subsidiary or branch publishes the report, and what happens with assurance and missing information. - 5 items ### [CSRD assurance evidence FAQ: what to keep for limited assurance](/artifacts/eu/corporate-sustainability-reporting-directive/faq/assurance-evidence.md) What CSRD and ESRS assurance evidence should support: management-report publication, the assurance report, national assurance procedures, and EU limited assurance milestones. - 5 items ### [CSRD data point inventory FAQ for ESRS disclosure readiness](/artifacts/eu/corporate-sustainability-reporting-directive/faq/data-point-inventory.md) How to build an ESRS data point inventory for CSRD reporting: disclosure requirements, materiality filters, evidence ownership, value-chain data, XBRL readiness, and assurance support. - 5 items ### [CSRD digital tagging and XBRL readiness FAQ](/artifacts/eu/corporate-sustainability-reporting-directive/faq/digital-tagging-xbrl.md) What CSRD teams should do now about XHTML, Inline XBRL, ESRS taxonomy materials, tagging controls, and limits before final digital taxonomy rules apply. - 4 items ### [CSRD omnibus stop-the-clock status: enacted delay vs proposed scope changes](/artifacts/eu/corporate-sustainability-reporting-directive/faq/omnibus-stop-the-clock-status.md) FAQ on the CSRD stop-the-clock directive, the separate Omnibus proposal, and how reporting teams should treat enacted and proposed changes. - 4 items ### [CSRD reporting waves FAQ: who reports first and what changed](/artifacts/eu/corporate-sustainability-reporting-directive/faq/reporting-waves.md) FAQ on original CSRD reporting waves, stop-the-clock caveats, listed SME opt-out, third-country reporting, and why local transposition law still matters. - 5 items ### [CSRD topical ESRS scoping: what must be reported?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/topical-esrs-scoping.md) FAQ on CSRD topical ESRS scoping: ESRS 2, double materiality, topical disclosure requirements, omitted topics, climate, and Appendix B datapoints. - 4 items ### [FAQ: CSRD double materiality scoring — thresholds, weighting, and evidence](/artifacts/eu/corporate-sustainability-reporting-directive/faq/double-materiality-scoring.md) How to score CSRD double materiality under ESRS without invented thresholds: impact materiality, financial materiality, evidence, and documentation. - 4 items ### [FAQ: CSRD value chain estimates — methods and proportionality under ESRS](/artifacts/eu/corporate-sustainability-reporting-directive/faq/value-chain-estimates.md) When ESRS permits value chain estimates, what to disclose about assumptions, accuracy, limits, and improvement plans. - 4 items ### [How do ESRS 1 and ESRS 2 structure CSRD reporting?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/esrs-1-and-2-structure.md) FAQ explaining how ESRS 1 general requirements and ESRS 2 general disclosures fit into CSRD reporting, materiality, and topical ESRS disclosures. - 4 items ### [LSME and VSME under EU CSRD: what SMEs should know](/artifacts/eu/corporate-sustainability-reporting-directive/faq/lsme-and-vsme.md) FAQ on LSME and VSME under the EU CSRD: listed SME reporting, the temporary opt-out, voluntary SME reporting, and value-chain requests. - 4 items ### [Taxonomy Article 8 KPIs under CSRD and ESRS](/artifacts/eu/corporate-sustainability-reporting-directive/faq/taxonomy-article-8-kpis.md) FAQ explaining how EU Taxonomy Article 8 KPI disclosures relate to CSRD, ESRS, and the Article 8 XBRL taxonomy. - 5 items Browse all indexed questions: [/artifacts/eu/corporate-sustainability-reporting-directive/faq/items](/artifacts/eu/corporate-sustainability-reporting-directive/faq/items.md) ## All FAQ items *Page 1 of 3. Showing 20 of 53 items.* ### [When does CSRD Article 40a apply to a third-country group?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/third-country-groups.md#when-does-csrd-article-40a-apply-to-a-third-country-group) *Module: [CSRD Article 40a third-country group reporting](/artifacts/eu/corporate-sustainability-reporting-directive/faq/third-country-groups.md)* Article 40a applies only when both the non-EU group trigger and an EU presence trigger are met. The third-country undertaking must generate more than EUR 150 million net turnover in the Union at group level, or individual level if group reporting is not applicable, for each of the last two consecutive financial years. - Check the third-country undertaking's EU net turnover for each of the last two consecutive financial years. - Identify whether the group has an EU subsidiary that is a large undertaking or a listed SME that is not a micro-undertaking. - Use the branch route only where the third-country undertaking does not have a qualifying EU subsidiary and the EU branch passes the branch turnover condition. - Do not use Article 40a threshold numbers in public copy or internal scoping unless they are tied back to the current Accounting Directive text. Sources for this answer: - [Consolidated Directive 2013/34/EU, Article 40a](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A02013L0034-20240528&ref=sorena.io) - Supports the Article 40a scope triggers for third-country undertakings, EU subsidiaries, EU branches, and EU net turnover. - [Directive (EU) 2024/1306](https://data.europa.eu/eli/dec/2024/1306/oj?ref=sorena.io) - Supports the financial-year 2028 application point for reporting by certain third-country undertakings. ### [Who publishes the CSRD third-country sustainability report in the EU?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/third-country-groups.md#who-publishes-the-csrd-third-country-sustainability-report-in-the-eu) *Module: [CSRD Article 40a third-country group reporting](/artifacts/eu/corporate-sustainability-reporting-directive/faq/third-country-groups.md)* The Article 40a report is not published directly by every entity in the non-EU group. Member States must require the qualifying EU subsidiary to publish and make accessible the sustainability report for the ultimate third-country parent at group level. - For a qualifying EU subsidiary, confirm the subsidiary category before assigning publication responsibility. - For a branch, confirm there is no qualifying EU subsidiary before relying on the branch route. - Record the reporting perimeter: ultimate third-country parent group level, or individual third-country undertaking level where group-level reporting is not applicable. - Keep the publication owner separate from data owners in the non-EU parent group so the EU entity can evidence its Article 40a role. Sources for this answer: - [Consolidated Directive 2013/34/EU, Article 40a](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A02013L0034-20240528&ref=sorena.io) - Supports which EU subsidiary or branch must publish and make accessible the third-country sustainability report. ### [What must happen if the non-EU parent does not provide all information?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/third-country-groups.md#what-must-happen-if-the-non-eu-parent-does-not-provide-all-information) *Module: [CSRD Article 40a third-country group reporting](/artifacts/eu/corporate-sustainability-reporting-directive/faq/third-country-groups.md)* Article 40a does not let the EU subsidiary or branch stay silent because the third-country undertaking withholds information. The subsidiary or branch must request the information needed to meet its obligation. - Keep the information request sent to the third-country undertaking. - Preserve the response, non-response, or partial data package received from the third-country undertaking. - Prepare the Article 40a statement when required information is missing after the request. - Make the report and statement consistent with the information actually in the EU entity's possession. Sources for this answer: - [Consolidated Directive 2013/34/EU, Article 40a](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A02013L0034-20240528&ref=sorena.io) - Supports the request-for-information step and the statement required when the third-country undertaking does not provide necessary information. ### [Is an assurance opinion required for Article 40a reports?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/third-country-groups.md#is-an-assurance-opinion-required-for-article-40a-reports) *Module: [CSRD Article 40a third-country group reporting](/artifacts/eu/corporate-sustainability-reporting-directive/faq/third-country-groups.md)* Yes. Member States must require the Article 40a sustainability report to be published with an assurance opinion from a person or firm authorised to give an opinion on sustainability reporting assurance under the law of the third-country undertaking or of a Member State. - Identify whether the assurance opinion comes from a person or firm authorised under third-country law or Member State law. - Keep the final assurance opinion with the report publication file. - If the opinion is missing, prepare the Article 40a statement rather than omitting the assurance issue. - Check Article 40d publication timing because the report, assurance opinion, and any required statement travel together. Sources for this answer: - [Consolidated Directive 2013/34/EU, Article 40a](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A02013L0034-20240528&ref=sorena.io) - Supports the assurance opinion requirement and the statement required if the opinion is not provided. ### [When does the Article 40a third-country reporting route start?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/third-country-groups.md#when-does-the-article-40a-third-country-reporting-route-start) *Module: [CSRD Article 40a third-country group reporting](/artifacts/eu/corporate-sustainability-reporting-directive/faq/third-country-groups.md)* Directive (EU) 2024/1306 says the reporting requirement for certain third-country undertakings applies only as of the financial year 2028. Use that application point for the route, but keep the Article 40a scope test and the publication deadline separate in internal scoping. Sources for this answer: - [Directive (EU) 2024/1306](https://data.europa.eu/eli/dec/2024/1306/oj?ref=sorena.io) - Supports the financial-year 2028 application point for certain third-country undertakings. ### [What evidence supports CSRD limited assurance?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/assurance-evidence.md#what-evidence-supports-csrd-limited-assurance) *Module: [CSRD assurance evidence FAQ: what to keep for limited assurance](/artifacts/eu/corporate-sustainability-reporting-directive/faq/assurance-evidence.md)* The core evidence is not a generic policy note. It is the chain from ESRS requirement to reported disclosure: materiality assessment, selected disclosure requirements and datapoints, source systems, calculations, estimates, approvals, and final sustainability-statement text. - ESRS scope record: material impacts, risks, opportunities, omitted non-material topics, and the disclosure requirements selected. - Datapoint support: source owner, system extract, calculation file, assumptions, estimation method, comparative figure, and review sign-off. - Control evidence: who prepared, reviewed, challenged, corrected, and approved each material disclosure before the management report was authorised. - Value-chain evidence: requests sent, responses received, gaps, reasons information could not be obtained, and plans to obtain missing information in future reporting periods. - Cross-reporting tie-out: references and explanations connecting sustainability disclosures with other management-report information and amounts in the financial statements. Sources for this answer: - [Directive (EU) 2022/2464 on corporate sustainability reporting](https://data.europa.eu/eli/dir/2022/2464/oj?ref=sorena.io) - Supports the CSRD requirement to include sustainability information in the management report and to report the process used to identify that information. - [Commission Delegated Regulation (EU) 2023/2772 adopting ESRS](https://data.europa.eu/eli/reg_del/2023/2772/oj?ref=sorena.io) - Supports evidence records tied to ESRS disclosure requirements, datapoints, estimates, comparative information, and prior-period corrections. ### [How does assurance evidence connect to management report publication?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/assurance-evidence.md#how-does-assurance-evidence-connect-to-management-report-publication) *Module: [CSRD assurance evidence FAQ: what to keep for limited assurance](/artifacts/eu/corporate-sustainability-reporting-directive/faq/assurance-evidence.md)* CSRD sustainability reporting is placed in a clearly identifiable dedicated section of the management report. Evidence should therefore match the version that management approves for issuance, not a spreadsheet or draft narrative that later diverges from the published report. - Archive the final sustainability statement as included in the management report, with approval date and reporting period. - Tie each material disclosure to the approved management-report page, section, or tagged report location. - For exemption cases, keep the parent-report link, assurance-opinion link, exemption statement, and any required translation record. - For third-country parent reliance, retain evidence that the consolidated sustainability reporting and assurance opinion were published under the applicable Article 30 route. Sources for this answer: - [Directive (EU) 2022/2464 on corporate sustainability reporting](https://data.europa.eu/eli/dir/2022/2464/oj?ref=sorena.io) - Supports the management-report placement, dedicated-section requirement, subsidiary exemption publication links, and third-country parent publication conditions. ### [What does the assurance report and opinion need evidence for?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/assurance-evidence.md#what-does-the-assurance-report-and-opinion-need-evidence-for) *Module: [CSRD assurance evidence FAQ: what to keep for limited assurance](/artifacts/eu/corporate-sustainability-reporting-directive/faq/assurance-evidence.md)* The assurance report must identify the entity, the sustainability reporting covered, the date and period covered, and the reporting framework applied. It must also describe the assurance scope, identify the assurance standards used, and include the assurance opinion required by the Accounting Directive as amended by CSRD. - Entity and period file: legal entity, consolidation boundary, annual or consolidated sustainability reporting, and reporting period. - Framework file: ESRS basis, any applicable Taxonomy Article 8 disclosures, and the standards or procedures used for assurance. - Scope file: disclosures included, disclosures omitted, assurance scope limitations, and unresolved evidence gaps escalated before signing. - Opinion file: signed and dated assurance report, joint opinion or disagreement paragraphs, and links to the published report package. Sources for this answer: - [Directive (EU) 2022/2464 on corporate sustainability reporting](https://data.europa.eu/eli/dir/2022/2464/oj?ref=sorena.io) - Supports the required written assurance report content, including entity, period, framework, scope, assurance standards, and opinion. ### [Which assurance standards or procedures apply before EU standards are adopted?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/assurance-evidence.md#which-assurance-standards-or-procedures-apply-before-eu-standards-are-adopted) *Module: [CSRD assurance evidence FAQ: what to keep for limited assurance](/artifacts/eu/corporate-sustainability-reporting-directive/faq/assurance-evidence.md)* CSRD says Member States must require statutory auditors and audit firms to use assurance standards adopted by the Commission. Until the Commission has adopted an assurance standard covering the same subject matter, Member States may apply national assurance standards, procedures, or requirements. - Record whether the engagement used Commission-adopted assurance standards or national standards, procedures, or requirements. - If national procedures apply, keep the national reference and the date from which it applies to the engagement. - Keep the engagement letter or assurance plan showing planning, risk consideration, response to risks, and expected conclusion type. - Do not describe an assurance engagement as based on a future EU standard unless that standard has actually been adopted and applies. Sources for this answer: - [Directive (EU) 2022/2464 on corporate sustainability reporting](https://data.europa.eu/eli/dir/2022/2464/oj?ref=sorena.io) - Supports the rule that Commission assurance standards govern once adopted, while national standards, procedures, or requirements may apply beforehand. - [ISSA 5000 overview from the IAASB](https://www.iaasb.org/focus-areas/understanding-international-standard-sustainability-assurance-5000?ref=sorena.io) - Supports awareness of ISSA 5000 as an international sustainability assurance standard relevant to assurance engagements and EU assurance discussions. ### [What future assurance-standard milestones should the evidence owner track?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/assurance-evidence.md#what-future-assurance-standard-milestones-should-the-evidence-owner-track) *Module: [CSRD assurance evidence FAQ: what to keep for limited assurance](/artifacts/eu/corporate-sustainability-reporting-directive/faq/assurance-evidence.md)* The CSRD milestone to track is the Commission's delegated acts for assurance standards. The Directive requires limited assurance standards no later than 1 October 2026, covering procedures such as engagement planning, risk consideration, responses to risks, and the type of conclusions in the assurance report or audit report. - Track 1 October 2026 for Commission delegated acts on limited assurance standards. - Track 1 October 2028 for Commission delegated acts on reasonable assurance standards, subject to feasibility assessment. - After each EU standard is adopted, update the assurance basis, engagement instructions, control descriptions, and evidence index. - Keep national-procedure evidence separately so reviewers can see which requirements applied before the EU standard covered the same subject matter. Sources for this answer: - [Directive (EU) 2022/2464 on corporate sustainability reporting](https://data.europa.eu/eli/dir/2022/2464/oj?ref=sorena.io) - Supports the 1 October 2026 limited assurance standard milestone and 1 October 2028 reasonable assurance standard milestone. ### [What should a CSRD data point inventory contain?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/data-point-inventory.md#what-should-a-csrd-data-point-inventory-contain) *Module: [CSRD data point inventory FAQ for ESRS disclosure readiness](/artifacts/eu/corporate-sustainability-reporting-directive/faq/data-point-inventory.md)* Start from ESRS disclosure requirements and data points, then add company-specific reporting controls. EFRAG IG 3 describes a data point as a clearly separable and specific piece of information required by ESRS Disclosure Requirements, generally at paragraph, subparagraph, or sub-subparagraph level. - Use ESRS 2 and topical ESRS disclosure requirements as the backbone of the register. - Keep ESRS 1 separate as a general-requirements standard because EFRAG IG 3 does not treat it as a worksheet of dedicated Disclosure Requirements. - Flag whether the data point is narrative, semi-narrative, numerical, a table, an MDR policy/action/metric/target item, conditional, voluntary, or subject to phase-in. - Record the accountable evidence owner, not only the sustainability-reporting coordinator. Sources for this answer: - [EFRAG ESRS implementation guidance documents](https://www.efrag.org/en/projects/esrs-implementation-guidance-documents?ref=sorena.io) - EFRAG's implementation guidance page identifies IG 3 as the Detailed ESRS Datapoints guidance and links it with IG 1 materiality and IG 2 value-chain guidance. - [European sustainability reporting standards (ESRS)](https://xbrl.efrag.org/e-esrs/esrs-set1-2023.html?ref=sorena.io) - The ESRS rendering supports using the adopted ESRS disclosure requirements and paragraph references as the authoritative basis for the inventory. ### [How should materiality filter the inventory?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/data-point-inventory.md#how-should-materiality-filter-the-inventory) *Module: [CSRD data point inventory FAQ for ESRS disclosure readiness](/artifacts/eu/corporate-sustainability-reporting-directive/faq/data-point-inventory.md)* Do not treat every ESRS row the same way. EFRAG IG 3 distinguishes data points that are mandatory irrespective of materiality from data points that depend on the materiality assessment, and EFRAG IG 1 explains that materiality of information applies at the Disclosure Requirement or data point level. - Separate ESRS 2 cross-cutting disclosures from topical disclosures that depend on material matters. - For policies, actions, targets, and metrics, show when MDR data points apply to a material sustainability matter. - Where a metric is omitted as not material, keep the materiality conclusion and rationale available for review. - If climate-change disclosures under ESRS E1 are omitted because no material climate IROs were identified, keep the explanation visible because ESRS expects an explanation for that outcome. Sources for this answer: - [EFRAG ESRS implementation guidance documents](https://www.efrag.org/en/projects/esrs-implementation-guidance-documents?ref=sorena.io) - EFRAG's IG 1 and IG 3 materials support linking each data point to the double materiality assessment and its information-level conclusions. - [Commission Delegated Regulation (EU) 2023/2772 adopting ESRS](https://data.europa.eu/eli/reg_del/2023/2772/oj?ref=sorena.io) - The delegated regulation contains the adopted ESRS requirements, including double materiality concepts and ESRS 2 disclosure requirements such as IRO-1 and IRO-2. ### [Who should own evidence for each ESRS data point?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/data-point-inventory.md#who-should-own-evidence-for-each-esrs-data-point) *Module: [CSRD data point inventory FAQ for ESRS disclosure readiness](/artifacts/eu/corporate-sustainability-reporting-directive/faq/data-point-inventory.md)* Evidence ownership should follow the data, not the reporting calendar. A data point about workforce headcount, greenhouse gas emissions, supplier policies, remediation channels, or financial effects usually needs a different process owner, source system, control, and approval trail. - Keep calculation workpapers for numerical data points, including units, boundaries, assumptions, reconciliations, and review sign-off. - Keep narrative support for text disclosures, including policy documents, board or management materials, stakeholder-input summaries, and source extracts. - For value-chain data gaps, document efforts to obtain primary information, reasons it was not available, estimation sources, and plans to improve future data collection. - Tie each evidence file to the ESRS paragraph and reporting-period version used, so a later reviewer can reproduce the disclosure. Sources for this answer: - [EFRAG ESRS implementation guidance documents](https://www.efrag.org/en/projects/esrs-implementation-guidance-documents?ref=sorena.io) - EFRAG's IG 2 value-chain guidance supports documenting value-chain information, estimates, reasonable efforts, and improvement plans where primary data is not available. - [Corporate Sustainability Reporting Directive (EU) 2022/2464](https://data.europa.eu/eli/dir/2022/2464/oj?ref=sorena.io) - The CSRD text supports retaining evidence for value-chain availability constraints and assurance, including efforts made, reasons information could not be obtained, and future plans. ### [How does the inventory support ESRS XBRL and digital reporting readiness?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/data-point-inventory.md#how-does-the-inventory-support-esrs-xbrl-and-digital-reporting-readiness) *Module: [CSRD data point inventory FAQ for ESRS disclosure readiness](/artifacts/eu/corporate-sustainability-reporting-directive/faq/data-point-inventory.md)* A spreadsheet of ESRS rows is not the final XBRL taxonomy, but it can prevent rework. EFRAG IG 3 says the list is not itself the ESRS XBRL Taxonomy and cannot be used as the basis for machine-readable reporting, but it can help structure human-readable reports so they are easier to digitalise. - Use the inventory to reduce duplicated or overlapping narrative disclosures before Inline XBRL tagging. - Mark data points that will need dimensions, breakdowns, or typed entity-specific details. - Track whether values are report-period facts, end-of-period facts, comparative facts, targets, baselines, milestones, or estimates. - Do not treat EFRAG illustrative reports as templates; use them only as technical illustrations where relevant. Sources for this answer: - [ESRS Set 1 XBRL Taxonomy explanatory note](https://xbrl.efrag.org/downloads/ESRS-Set1-XBRL-Taxonomy-Explanatory-Note-and-Basis-for-Conclusions.pdf?ref=sorena.io) - EFRAG's XBRL taxonomy explanatory note supports tracking data types, tagging rules, narrative tagging, validation, dimensions, and entity-specific digital disclosures. - [EFRAG ESRS implementation guidance documents](https://www.efrag.org/en/projects/esrs-implementation-guidance-documents?ref=sorena.io) - EFRAG's IG 3 materials support using the detailed data point list as a bridge from human-readable ESRS preparation to later digital reporting work. ### [What makes the inventory assurance-ready?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/data-point-inventory.md#what-makes-the-inventory-assurance-ready) *Module: [CSRD data point inventory FAQ for ESRS disclosure readiness](/artifacts/eu/corporate-sustainability-reporting-directive/faq/data-point-inventory.md)* An assurance-ready CSRD data point inventory is traceable, versioned, and reviewable. It should show the reporting framework applied, the disclosure period, the ESRS requirement, the materiality conclusion, the evidence owner, the control performed, the evidence retained, and any unresolved limitation or estimate. - Freeze a reporting-period version of the inventory before assurance fieldwork and preserve later changes as controlled revisions. - Require preparer and reviewer sign-off for each material data point, including narratives and omissions. - Flag high-risk rows: manual calculations, value-chain estimates, newly material IROs, entity-specific disclosures, and data points with weak controls. - Keep an exception log for unavailable data, late evidence, changed assumptions, restatements, and unresolved reviewer comments. Sources for this answer: - [Corporate Sustainability Reporting Directive (EU) 2022/2464](https://data.europa.eu/eli/dir/2022/2464/oj?ref=sorena.io) - The CSRD text supports the assurance-ready evidence emphasis because it introduced assurance of sustainability reporting and assurance file documentation requirements. - [Commission Delegated Regulation (EU) 2023/2772 adopting ESRS](https://data.europa.eu/eli/reg_del/2023/2772/oj?ref=sorena.io) - The adopted ESRS support linking evidence to disclosure requirements, internal controls over sustainability reporting, and the qualitative characteristics of reported information. ### [Is CSRD sustainability reporting already required to be tagged in XBRL?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/digital-tagging-xbrl.md#is-csrd-sustainability-reporting-already-required-to-be-tagged-in-xbrl) *Module: [CSRD digital tagging and XBRL readiness](/artifacts/eu/corporate-sustainability-reporting-directive/faq/digital-tagging-xbrl.md)* Not as a blanket final obligation in the grounded Commission FAQ. Article 29d points undertakings that publish a sustainability statement toward XHTML and mark-up in accordance with a digital taxonomy to be specified by an amendment to the ESEF Delegated Regulation. - Do not tell teams that final CSRD XBRL tagging is already fully operational unless the applicable delegated ESEF update and national filing rules support that conclusion. - Do prepare the sustainability statement so disclosures can be mapped to ESRS data points, Article 8 disclosures, reporting period, entity boundary, units, and evidence owners. - Separate current report-production requirements from future tagging readiness in board, audit, and project documentation.

For each ESRS disclosure requirement and material data point, keep the human-readable disclosure text, source system, calculation owner, review sign-off, and the candidate ESRS taxonomy concept or reason no direct concept is available. - Map ESRS 1 and ESRS 2 disclosures, topical ESRS disclosures, and entity-specific disclosures separately so narrative, semi-narrative, numeric, and dimensional data can be reviewed with different controls. - Maintain a data-point register with ESRS reference, disclosure text, unit, period type, dimension or disaggregation, source evidence, calculation method, and reviewer. - Flag taxonomy extensions or entity-specific disclosures early; they usually require stronger review because the tag choice is not a simple one-to-one match to a core element. - Keep Article 8 Taxonomy Regulation disclosures in scope for readiness because CSRD Article 29d refers to marking up sustainability reporting including Article 8 disclosures.

The control objective is not only visual consistency; it is also machine-readable consistency between the XHTML presentation, Inline XBRL facts, contexts, units, dimensions, labels, and extension taxonomy files. - Run a tie-out between the board-approved sustainability statement and every tagged fact, including hidden or transformed facts. - Validate contexts for reporting entity, period, scenario and segment use; sustainability metrics should not drift from the reporting boundary used in the human-readable statement. - Review unit, scale, sign, and transformation settings for numeric facts, especially emissions, energy, water, monetary, percentage, and intensity values. - Require technical validation of Inline XBRL and extension taxonomy files before filing, then preserve the validation report with the assurance and publication record. - Check that the XHTML or Inline XBRL report package is standalone and does not rely on external resources for content that should be inside the reporting package. Sources for this answer: - [ESMA ESEF Reporting Manual](https://www.esma.europa.eu/document/esef-reporting-manual?ref=sorena.io) - Supports XHTML, Inline XBRL, extension taxonomy, validation, and report-package controls that are relevant to digital-reporting readiness. - [ESMA consultation paper on ESEF sustainability reporting RTS](https://www.esma.europa.eu/document/consultation-paper-rts-european-single-electronic-format-esef-sustainability-reporting-and?ref=sorena.io) - Supports ESEF sustainability-reporting mark-up readiness, including extension, validation, and future manual-guidance topics. - [ESMA update on the 2024 ESEF Reporting Manual](https://www.esma.europa.eu/press-news/esma-news/esma-publishes-2024-esef-reporting-manual?ref=sorena.io) - Supports practical controls for empty fields, extension element anchoring, block-tag readability, and unique identifiers for tagged facts. ### [What evidence should auditors and reviewers expect for CSRD tagging readiness?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/digital-tagging-xbrl.md#what-evidence-should-auditors-and-reviewers-expect-for-csrd-tagging-readiness) *Module: [CSRD digital tagging and XBRL readiness](/artifacts/eu/corporate-sustainability-reporting-directive/faq/digital-tagging-xbrl.md)* Keep evidence that proves the report can move from human-readable ESRS content to machine-readable facts without losing meaning. The evidence should be understandable to sustainability, finance, audit, and technical reviewers. - Legal basis: CSRD Article 29d assessment, applicable national filing position, ESEF delegated-act status, and any authority guidance relied on. - Standards basis: ESRS disclosure inventory, materiality decisions, Article 8 disclosure inventory, taxonomy concept candidates, and extension rationale. - Data basis: source-system extracts, calculation workpapers, unit and scale checks, period and boundary checks, and reviewer sign-offs. - Technical basis: XHTML or Inline XBRL package, taxonomy package, validation logs, warnings disposition, anchoring review, and final filed version hash or archive reference. - Limit record: unresolved items that depend on final ESEF sustainability tagging rules, software certification, national filing portal requirements, or assurance-scope decisions.

The Commission's corporate sustainability reporting page links the measure to Directive (EU) 2024/1306 and describes it as postponing the entry into application for wave two and wave three companies. - Use the stop-the-clock directive for timing analysis where the entity was previously first due for financial years 2025 or 2026. - Do not present the proposed Omnibus scope reduction as final unless a later enacted source is added to the evidence file. - Keep ESRS reporting work active for entities that are already in the first reporting wave or still clearly in scope under enacted rules.
