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 2 of 3. Showing 20 of 53 items.* ### [What did the stop-the-clock directive change, and what did it not change?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/omnibus-stop-the-clock-status.md#what-did-the-stop-the-clock-directive-change-and-what-did-it-not-change) *Module: [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)* It changed timing for the affected later CSRD reporting waves. It did not, based on the sources used for this FAQ, enact the wider Omnibus proposal to reduce mandatory CSRD scope to companies with more than 1000 employees. - Enacted: stop-the-clock timing postponement for companies previously first due for financial years 2025 or 2026. - Proposed: applying CSRD only to the largest companies and reducing value-chain burden on smaller companies. - Still relevant: ESRS remains the reporting baseline for companies that must report under the currently applicable CSRD framework.

If the company was previously first required to report for financial years 2025 or 2026, mark the stop-the-clock timing issue as an enacted legal change and update the reporting calendar without inventing substitute dates that are not in the evidence file. - Identify whether the entity is a wave two or wave three company in the existing CSRD plan. - Record Directive (EU) 2024/1306 as the source for any stop-the-clock timing change. - Keep the broader Omnibus scope change in a pending-proposal status until enacted evidence is available. - Continue maintaining materiality, ESRS data, assurance-readiness, and governance evidence where the entity remains in scope or status is uncertain. Sources for this answer: - [Directive (EU) 2022/2464 as regards corporate sustainability reporting](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32022L2464&ref=sorena.io) - Primary CSRD source for the underlying corporate sustainability reporting framework amended by later timing and standards measures. - [Commission Delegated Regulation (EU) 2023/2772 on ESRS](https://data.europa.eu/eli/reg_del/2023/2772/oj?ref=sorena.io) - Primary ESRS source showing that the reporting standards remain the baseline for undertakings required to report under the CSRD framework. ### [What evidence should support a stop-the-clock status note?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/omnibus-stop-the-clock-status.md#what-evidence-should-support-a-stop-the-clock-status-note) *Module: [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)* Keep the evidence narrow and source-specific. The file should show the entity's original CSRD wave, why the stop-the-clock directive applies or does not apply, and which Omnibus items are being tracked only as proposals. - Entity and group boundary used for the CSRD wave assessment. - Original first reporting year classification from the company's pre-stop-the-clock CSRD plan. - Source citation for Directive (EU) 2024/1306 and the Commission status page. - Separate proposal tracker entry for Omnibus scope, value-chain cap, and future voluntary-standard measures. - Review owner and trigger for updating the note when a later enacted EU source changes the status. Sources for this answer: - [European Commission corporate sustainability reporting page](https://finance.ec.europa.eu/capital-markets-union-and-financial-markets/company-reporting-and-auditing/company-reporting/corporate-sustainability-reporting_en?ref=sorena.io) - Supports keeping stop-the-clock, quick-fix ESRS, and broader Omnibus items as separate status entries in the reporting plan. - [Questions and answers on the VSME Recommendation and Omnibus I proposal](https://finance.ec.europa.eu/publications/questions-and-answers-recommendation-voluntary-sustainability-reporting-standard-small-and-medium_en?ref=sorena.io) - Supports tracking the proposed voluntary standard and value-chain cap separately because their content and timing depend on the Omnibus legislative negotiations. ### [What were the original CSRD reporting waves?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/reporting-waves.md#what-were-the-original-csrd-reporting-waves) *Module: [CSRD reporting waves FAQ: who reports first and what changed](/artifacts/eu/corporate-sustainability-reporting-directive/faq/reporting-waves.md)* Directive (EU) 2022/2464 set phased application dates by financial year. The first wave covered large public-interest entities and parent undertakings of large groups that exceeded the 500-employee condition. The second wave covered other large undertakings and parent undertakings of large groups. The third wave covered listed SMEs that are not micro-undertakings, plus listed small and non-complex institutions and captive insurance or reinsurance undertakings where the CSRD conditions are met. - Financial years starting on or after 1 January 2024: large public-interest entities and large-group parents above the 500-employee condition. - Financial years starting on or after 1 January 2025: other large undertakings and other parent undertakings of large groups. - Financial years starting on or after 1 January 2026: listed SMEs that are not micro-undertakings, plus qualifying listed small and non-complex institutions and captive insurance or reinsurance undertakings. - Financial years starting on or after 1 January 2028: the CSRD third-country reporting route introduced through Article 40a. Sources for this answer: - [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 original CSRD phased application years, the affected entity categories, the transposition obligation, and the third-country Article 40a application date. - [European Commission corporate sustainability reporting overview](https://finance.ec.europa.eu/capital-markets-union-and-financial-markets/company-reporting-and-auditing/company-reporting/corporate-sustainability-reporting_en?ref=sorena.io) - Confirms that the first CSRD companies applied the new rules for the 2024 financial year and published reports in 2025. ### [Did the stop-the-clock measure erase the original waves?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/reporting-waves.md#did-the-stop-the-clock-measure-erase-the-original-waves) *Module: [CSRD reporting waves FAQ: who reports first and what changed](/artifacts/eu/corporate-sustainability-reporting-directive/faq/reporting-waves.md)* No. The original CSRD wave rules still matter as the starting point for scoping. The Commission's CSRD page says the stop-the-clock Directive postpones the entry into application of reporting requirements for companies that were previously due to report for the first time for financial years 2025 or 2026, described there as wave two and wave three companies. - Wave one companies are not described in the Commission source as the stop-the-clock target; the same page separately notes a quick-fix delegated act giving additional ESRS flexibility to wave one companies for financial years 2025 and 2026. - Wave two and wave three companies need a current-law check because the EU-level caveat changes entry into application, but local implementation can still control the practical filing analysis. - A reporting-wave memo should record the original CSRD wave, any stop-the-clock reliance, the Member State or issuer regime checked, and the source date used for the conclusion. Sources for this answer: - [European Commission corporate sustainability reporting overview](https://finance.ec.europa.eu/capital-markets-union-and-financial-markets/company-reporting-and-auditing/company-reporting/corporate-sustainability-reporting_en?ref=sorena.io) - Supports the stop-the-clock caveat for wave two and wave three companies and the separate quick-fix flexibility note for wave one companies. - [Stop-the-clock Directive (EU) 2025/794](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32025L0794&ref=sorena.io) - Official EUR-Lex source identified by the Commission page for the stop-the-clock directive affecting CSRD entry into application. ### [Can listed SMEs opt out of CSRD reporting before 2028?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/reporting-waves.md#can-listed-smes-opt-out-of-csrd-reporting-before-2028) *Module: [CSRD reporting waves FAQ: who reports first and what changed](/artifacts/eu/corporate-sustainability-reporting-directive/faq/reporting-waves.md)* Yes, but only for the listed SME category described by the Accounting Directive rules. The Commission FAQ explains that SMEs, excluding micro-undertakings, with transferable securities admitted to trading on an EU regulated market may decide not to report under Article 19a for financial years starting before 1 January 2028. If they use that opt-out, they must briefly state in the management report why the sustainability reporting was not provided. - Confirm the entity is an SME and not a micro-undertaking. - Confirm its transferable securities are admitted to trading on an EU regulated market. - If the opt-out is used, include the required short explanation in the management report rather than simply omitting the sustainability statement silently. - Do not treat the listed SME opt-out as a general exemption for private SMEs or for large listed entities. Sources for this answer: - [European Commission FAQ on implementation of EU corporate sustainability reporting rules](https://finance.ec.europa.eu/publications/frequently-asked-questions-implementation-eu-corporate-sustainability-reporting-rules_en?ref=sorena.io) - Supports the listed SME opt-out, the exclusion of micro-undertakings, the pre-2028 financial-year condition, and the management-report explanation requirement. - [Directive (EU) 2022/2464 on corporate sustainability reporting](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32022L2464&ref=sorena.io) - Contains the Article 19a(7) opt-out text for small and medium-sized public-interest entities before financial years starting on 1 January 2028. ### [How do CSRD reporting waves work for third-country undertakings?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/reporting-waves.md#how-do-csrd-reporting-waves-work-for-third-country-undertakings) *Module: [CSRD reporting waves FAQ: who reports first and what changed](/artifacts/eu/corporate-sustainability-reporting-directive/faq/reporting-waves.md)* There are two different third-country questions. First, a third-country issuer with transferable securities admitted to trading on an EU regulated market can be caught by the issuer route under Articles 19a or 29a, excluding micro-undertakings; the Commission FAQ says those issuers include sustainability information in the management report as part of the annual financial report. - Check whether the third-country company is an EU-regulated-market issuer before using the Article 40a branch or subsidiary route. - For Article 40a, identify the EU subsidiary or branch that would publish and make the report accessible. - Check the EU turnover and branch turnover facts against audited or management-reporting records. - If a third-country undertaking withholds the required assurance opinion for an Article 40a report, the EU subsidiary or branch must issue a statement indicating that fact. Sources for this answer: - [Directive (EU) 2022/2464 on corporate sustainability reporting](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32022L2464&ref=sorena.io) - Supports Article 40a third-country group scope, the EUR 150 million Union net turnover condition, the EUR 40 million branch condition, publication responsibility, and the 2028 application point. - [European Commission FAQ on implementation of EU corporate sustainability reporting rules](https://finance.ec.europa.eu/publications/frequently-asked-questions-implementation-eu-corporate-sustainability-reporting-rules_en?ref=sorena.io) - Supports the distinction between third-country issuers under Articles 19a/29a and the assurance-opinion statement for Article 40a reports. ### [Why should teams confirm local law before relying on a CSRD wave answer?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/reporting-waves.md#why-should-teams-confirm-local-law-before-relying-on-a-csrd-wave-answer) *Module: [CSRD reporting waves FAQ: who reports first and what changed](/artifacts/eu/corporate-sustainability-reporting-directive/faq/reporting-waves.md)* CSRD is a directive. Directive (EU) 2022/2464 required Member States to bring national laws, regulations, and administrative provisions into force and communicate those measures to the Commission. That means an EU-level wave analysis is necessary but not always sufficient for filing, assurance-provider, register, publication, and sanction questions. - Record the Member State law or issuer home Member State checked. - Confirm whether national law changes the practical publication channel, assurance-provider rules, or enforcement exposure. - Keep the CSRD source, the national-law source, the entity classification evidence, and the reporting-year conclusion together. Sources for this answer: - [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 Member State transposition requirement and the need to check national implementing measures for practical application. - [European Commission FAQ on implementation of EU corporate sustainability reporting rules](https://finance.ec.europa.eu/publications/frequently-asked-questions-implementation-eu-corporate-sustainability-reporting-rules_en?ref=sorena.io) - Supports local-law checks for areas where the FAQ identifies Member State rules or national regimes as relevant to implementation. ### [Does every CSRD reporter have to report every topical ESRS?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/topical-esrs-scoping.md#does-every-csrd-reporter-have-to-report-every-topical-esrs) *Module: [CSRD topical ESRS scoping: what must be reported?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/topical-esrs-scoping.md)* No. The Commission explains that ESRS 2 General Disclosures is mandatory for companies in CSRD scope, while the other standards, disclosure requirements, and datapoints are subject to materiality assessment. That means the undertaking reports relevant information and may omit information that is not material for its business model and activity. - Start with ESRS 2 because its cross-cutting disclosures apply irrespective of which sustainability matter is considered. - Assess topical ESRS by impacts, risks, and opportunities, including both impact materiality and financial materiality. - When a topical matter is material, use the related ESRS disclosure requirements to identify the information to report. - If a material impact, risk, or opportunity is not covered or is insufficiently covered by ESRS, add entity-specific disclosure rather than leaving the matter unexplained. Sources for this answer: - [European sustainability reporting standards (ESRS)](https://xbrl.efrag.org/e-esrs/esrs-set1-2023.html?ref=sorena.io) - Supports ESRS 2 IRO-2, the content-index requirement, omitted-topic treatment, and the definitions of materiality, impact materiality, and financial materiality. - [Questions and Answers on the Adoption of European Sustainability Reporting Standards](https://ec.europa.eu/commission/presscorner/detail/en/qanda_23_4043?ref=sorena.io) - Explains that ESRS 2 is mandatory for CSRD-scope companies and that all other standards, disclosure requirements, and datapoints are subject to materiality assessment. ### [How should teams scope topical ESRS after finding a material matter?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/topical-esrs-scoping.md#how-should-teams-scope-topical-esrs-after-finding-a-material-matter) *Module: [CSRD topical ESRS scoping: what must be reported?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/topical-esrs-scoping.md)* Move from the material sustainability matter to the related disclosure requirements, then to the specific datapoints needed to meet those requirements. EFRAG's implementation guidance describes this as determining material matters first and then determining material information at the more granular level of disclosure requirements or datapoints. - Identify actual and potential impacts, risks, and opportunities connected with the topic. - Decide whether the matter is material from the impact perspective, financial perspective, or both. - Map material matters to ESRS topical standards and disclosure requirements. - Apply materiality of information at disclosure-requirement and datapoint level so the sustainability statement includes relevant, faithful, decision-useful information. - Document thresholds or criteria used to determine which information is material, because ESRS 2 IRO-2 requires an explanation of that determination. Sources for this answer: - [ESRS implementation guidance documents](https://www.efrag.org/en/projects/esrs-implementation-guidance-documents?ref=sorena.io) - Identifies EFRAG's non-authoritative IG 1 materiality guidance, IG 2 value-chain guidance, and IG 3 datapoint list as implementation support for ESRS scoping. - [European sustainability reporting standards (ESRS)](https://xbrl.efrag.org/e-esrs/esrs-set1-2023.html?ref=sorena.io) - Supports the requirement in ESRS 2 IRO-2 to explain how material information was determined, including thresholds and ESRS 1 materiality criteria. ### [What must still be disclosed when a topical ESRS is not material?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/topical-esrs-scoping.md#what-must-still-be-disclosed-when-a-topical-esrs-is-not-material) *Module: [CSRD topical ESRS scoping: what must be reported?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/topical-esrs-scoping.md)* A non-material topical ESRS is not simply invisible. ESRS 2 IRO-2 requires the sustainability statement to list the disclosure requirements complied with and to make understandable which topics were omitted as not material as a result of the materiality assessment. - Provide the ESRS 2 IRO-2 list of disclosure requirements included in the sustainability statement, with page or paragraph references. - Explain how material information was determined for the material impacts, risks, and opportunities that are reported. - For a fully omitted ESRS E1 Climate change standard, include the detailed non-materiality explanation and forward-looking analysis required by ESRS 2. - For other fully omitted topical ESRS, consider a brief explanation of the materiality-assessment conclusion so users can understand why the topic is absent. Sources for this answer: - [European sustainability reporting standards (ESRS)](https://xbrl.efrag.org/e-esrs/esrs-set1-2023.html?ref=sorena.io) - Provides the ESRS 2 IRO-2 rules for listing reported disclosure requirements, omitted topics, the special ESRS E1 climate explanation, and optional brief explanations for other omitted topical standards. - [Questions and Answers on the Adoption of European Sustainability Reporting Standards](https://ec.europa.eu/commission/presscorner/detail/en/qanda_23_4043?ref=sorena.io) - Confirms the Commission's policy explanation that a company omitting climate change as non-material has to provide a detailed explanation of its materiality-assessment conclusions. ### [How do Appendix B and EU-law datapoints affect topical ESRS scoping?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/topical-esrs-scoping.md#how-do-appendix-b-and-eu-law-datapoints-affect-topical-esrs-scoping) *Module: [CSRD topical ESRS scoping: what must be reported?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/topical-esrs-scoping.md)* Some ESRS datapoints correspond to information needed under other EU sustainable-finance frameworks, including SFDR, benchmark, and Capital Requirements Regulation disclosures. ESRS 2 IRO-2 requires a table of all Appendix B datapoints that derive from other EU legislation, showing where they appear in the sustainability statement or marking them as not material. - Build a content index for disclosure requirements included in the sustainability statement. - Maintain an Appendix B datapoint table for EU-law-derived datapoints. - When an Appendix B datapoint is not material, mark it as Not material in the table rather than just omitting it. - Keep the basis for not-material conclusions aligned with the same materiality thresholds and criteria used for other ESRS information. Sources for this answer: - [European sustainability reporting standards (ESRS)](https://xbrl.efrag.org/e-esrs/esrs-set1-2023.html?ref=sorena.io) - Supports the ESRS 2 IRO-2 Appendix B table requirement for EU-law-derived datapoints and the instruction to indicate Not material where applicable. - [Questions and Answers on the Adoption of European Sustainability Reporting Standards](https://ec.europa.eu/commission/presscorner/detail/en/qanda_23_4043?ref=sorena.io) - Explains why SFDR, benchmark, and CRR-related datapoints must be explicitly stated as not material when omitted for materiality reasons. ### [Does ESRS prescribe a numeric double materiality score?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/double-materiality-scoring.md#does-esrs-prescribe-a-numeric-double-materiality-score) *Module: [FAQ: CSRD double materiality scoring — thresholds, weighting, and evidence](/artifacts/eu/corporate-sustainability-reporting-directive/faq/double-materiality-scoring.md)* No. ESRS uses double materiality as the basis for sustainability disclosures, but it does not prescribe one fixed numeric score, rating scale, or cut-off that every undertaking must use. - Start with a long list of sustainability impacts, risks, and opportunities across own operations and the upstream and downstream value chain. - Score impact materiality and financial materiality separately before consolidating the result. - Treat a matter as material if it is material from the impact perspective, the financial perspective, or both. - Record the qualitative or quantitative threshold used and why it fits the undertaking's facts.

It should not only show final red, amber, or green labels. - Context: activities, products, services, geographies, business relationships, and value-chain boundaries considered. - Impact evidence: stakeholder input, due diligence findings, incident data, grievance data, scientific evidence, and expert input used for scale, scope, irremediability, and likelihood. - Financial evidence: risk registers, forecasts, sensitivity analysis, financing discussions, cost assumptions, and links to financial statement assumptions where relevant. - Threshold record: the qualitative and quantitative thresholds used, who approved them, and where judgement was applied because evidence was inconclusive. - Outcome record: material IROs, non-material conclusions where retained, omitted topical disclosures, and the rationale for any climate-change non-materiality conclusion. Sources for this answer: - [European sustainability reporting standards (ESRS)](https://xbrl.efrag.org/e-esrs/esrs-set1-2023.html?ref=sorena.io) - Supports the need to describe materiality-assessment processes and disclosure requirements covered by the sustainability statement. - [Questions and Answers on the Adoption of European Sustainability Reporting Standards](https://ec.europa.eu/commission/presscorner/detail/en/qanda_23_4043?ref=sorena.io) - Supports that materiality-assessment conclusions affect which ESRS information is reported and are subject to assurance. ### [Can CSRD reporters use estimates for value chain information under ESRS?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/value-chain-estimates.md#can-csrd-reporters-use-estimates-for-value-chain-information-under-esrs) *Module: [FAQ: CSRD value chain estimates — methods and proportionality under ESRS](/artifacts/eu/corporate-sustainability-reporting-directive/faq/value-chain-estimates.md)* Yes. ESRS 1 requires the sustainability statement to include material upstream and downstream value chain information where it is needed to explain material impacts, risks, and opportunities. It also says that if the undertaking cannot collect the required value chain information after reasonable efforts, it shall estimate the information using reasonable and supportable information, including sector-average data and other proxies. - Start with the material impact, risk, or opportunity, not a full population of every value chain actor. - Record what direct information was requested or reviewed and why it was unavailable, incomplete, or unreliable. - Use supportable indirect information such as sector averages, country or regional risk data, sample analyses, market data, peer group data, or product-level proxies where those inputs fit the matter. - Do not use a proxy if it would make the disclosed metric arbitrary or misleading for the material matter. Sources for this answer: - [European sustainability reporting standards (ESRS)](https://xbrl.efrag.org/e-esrs/esrs-set1-2023.html?ref=sorena.io) - ESRS 1 paragraphs 63 to 72 set the value-chain reporting boundary and permit estimates after reasonable efforts to collect required information. - [Commission Delegated Regulation (EU) 2023/2772](https://data.europa.eu/eli/reg_del/2023/2772/oj?ref=sorena.io) - The Delegated Regulation is the official EU legal act adopting the ESRS set used for CSRD sustainability reporting. ### [What should be disclosed when an ESRS value chain metric uses estimates?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/value-chain-estimates.md#what-should-be-disclosed-when-an-esrs-value-chain-metric-uses-estimates) *Module: [FAQ: CSRD value chain estimates — methods and proportionality under ESRS](/artifacts/eu/corporate-sustainability-reporting-directive/faq/value-chain-estimates.md)* When metrics include value chain data estimated from indirect sources, the disclosure should identify the metric, explain the basis for preparation, describe the resulting level of accuracy, and, where applicable, describe planned actions to improve accuracy in the future. - Metric affected: name the datapoint or entity-specific metric that includes estimated upstream or downstream value chain data. - Reason for estimation: explain why direct primary information was not available after reasonable efforts. - Inputs and method: name the proxy data source type and the main calculation assumptions without overstating precision. - Accuracy statement: describe whether accuracy is high, moderate, limited, or otherwise constrained, and why. - Improvement plan: state planned actions such as supplier data collection, better geographic segmentation, sampling, system changes, or updated proxy selection. Sources for this answer: - [European sustainability reporting standards (ESRS)](https://xbrl.efrag.org/e-esrs/esrs-set1-2023.html?ref=sorena.io) - ESRS 1 section 7.2 explains estimation uncertainty, and ESRS 2 BP-2 addresses metrics that include value chain data estimated from indirect sources. - [EFRAG IG 2: Value Chain Implementation Guidance](https://www.efrag.org/sites/default/files/sites/webpublishing/SiteAssets/EFRAG%20IG%202%20Value%20Chain.pdf?ref=sorena.io) - EFRAG IG 2 explains how to disclose metrics using value chain estimates, including basis, accuracy, and improvement actions. ### [How should teams document reasonable efforts before using a value chain estimate?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/value-chain-estimates.md#how-should-teams-document-reasonable-efforts-before-using-a-value-chain-estimate) *Module: [FAQ: CSRD value chain estimates — methods and proportionality under ESRS](/artifacts/eu/corporate-sustainability-reporting-directive/faq/value-chain-estimates.md)* The documentation should show why an estimate was needed and why the chosen proxy is supportable for the material matter. It should be specific enough for reporting, finance, procurement, sustainability, and assurance reviewers to follow the same trail from source data to disclosure. - Value chain scope: affected product, service, geography, activity, supplier group, customer group, or indirect business relationship. - Materiality link: the impact, risk, or opportunity that makes the value chain information necessary. - Reasonable-efforts log: requests made, internal data reviewed, public data reviewed, supplier or customer limits, and known reliability issues. - Proxy selection memo: why the selected sector, country, product, sample, market, peer, or other indirect data is reasonable and supportable. - Assumption register: variables, data vintage, exclusions, sensitivity points, and consistency with related financial or operational assumptions where relevant. - Review control: preparer, reviewer, approval date, changes from the prior period, and the trigger for revisiting the estimate. Sources for this answer: - [European sustainability reporting standards (ESRS)](https://xbrl.efrag.org/e-esrs/esrs-set1-2023.html?ref=sorena.io) - ESRS 1 requires reasonable and supportable information for value chain estimates and addresses updates when new information affects estimates. - [EFRAG IG 2: Value Chain Implementation Guidance](https://www.efrag.org/sites/default/files/sites/webpublishing/SiteAssets/EFRAG%20IG%202%20Value%20Chain.pdf?ref=sorena.io) - EFRAG IG 2 gives practical examples of using sector, country, sample, market, peer group, and other proxy data where primary value-chain data is unavailable. ### [What are the limits of using estimates for CSRD value chain reporting?](/artifacts/eu/corporate-sustainability-reporting-directive/faq/value-chain-estimates.md#what-are-the-limits-of-using-estimates-for-csrd-value-chain-reporting) *Module: [FAQ: CSRD value chain estimates — methods and proportionality under ESRS](/artifacts/eu/corporate-sustainability-reporting-directive/faq/value-chain-estimates.md)* Estimates are acceptable only within the ESRS reporting logic. They cannot replace the materiality assessment, hide a known data gap, or turn unsupported information into a reliable metric. ESRS 1 says that incorporating sector-average data or other proxies must not result in information that fails the qualitative characteristics of information. - Do not estimate every actor when ESRS only requires material upstream or downstream value chain information. - Do not present proxy output as primary data from a supplier, customer, facility, or worker group. - Do not reuse a proxy when geography, product mix, activity, or business relationship changes make it stale. - Do not ignore contradictory information received before the management report is approved if it provides evidence about conditions at period end. - Do not assume buying power or leverage changes materiality; it may affect data access and improvement plans, but materiality still follows impacts, risks, and opportunities.
