EU Taxonomy Article 8 adds disclosures on how and to what extent covered undertakings' activities are associated with environmentally sustainable economic activities. This comparison helps separate double-materiality reporting from taxonomy eligibility, alignment, KPI templates, and digital tagging work. CSRD and EU Taxonomy Article 8 are connected but not interchangeable. Companies subject to CSRD report under ESRS in a sustainability statement, while Article 8 of the Taxonomy Regulation and Delegated Regulation (EU) 2021/2178 specify taxonomy disclosures and KPI methodologies for undertakings that must publish sustainability information under Articles 19a or 29a of the Accounting Directive. ## CSRD vs EU Taxonomy Article 8 disclosures Read the EU Taxonomy side as the Article 8 disclosure and KPI layer, not as a replacement for CSRD or ESRS reporting. - **CSRD and ESRS**: CSRD amends the Accounting Directive and requires in-scope undertakings to report sustainability information according to ESRS in a dedicated section of the management report. - **EU Taxonomy Article 8**: Article 8 requires disclosure of how and to what extent activities are associated with environmentally sustainable economic activities; Delegated Regulation (EU) 2021/2178 specifies content, presentation, and KPI methodology. | Dimension | CSRD and ESRS | EU Taxonomy Article 8 | Operational implication | Sources | | --- | --- | --- | --- | --- | | Scope boundary | CSRD scope follows the Accounting Directive reporting categories as amended by CSRD, including large undertakings, listed SMEs other than micro-undertakings, and parent undertakings of large groups according to the applicable provisions. | Article 8 applies to undertakings subject to the obligation to publish sustainability information under Articles 19a or 29a of the Accounting Directive, and asks for information on how and to what extent activities are associated with environmentally sustainable economic activities. | Start with the CSRD or Accounting Directive reporting obligation, then decide which Article 8 template and KPI rules apply. Do not run Article 8 as a standalone voluntary green-claim test. | [Commission Delegated Regulation (EU) 2023/2772](https://data.europa.eu/eli/reg_del/2023/2772/oj?ref=sorena.io) - Identifies the CSRD reporting categories referenced by ESRS adoption.

ESRS still requires materiality-based narrative, metrics, policies, actions, targets, and basis-of-preparation disclosures where applicable. | [Corporate sustainability reporting](https://finance.ec.europa.eu/capital-markets-union-and-financial-markets/company-reporting-and-auditing/company-reporting/corporate-sustainability-reporting_en?ref=sorena.io) - Explains that EU law requires covered companies to disclose sustainability risks, opportunities, and impacts, and that CSRD companies report according to ESRS.

[Commission Delegated Regulation (EU) 2021/2178](https://data.europa.eu/eli/reg_del/2021/2178/oj?ref=sorena.io) - Supports the separate taxonomy KPI methodology and presentation layer. | | Trigger | ESRS uses double materiality: a sustainability matter is material if it is material from the impact perspective, the financial perspective, or both. | Taxonomy alignment is an activity-level classification and disclosure exercise under the Taxonomy Regulation and its delegated acts, including technical screening and KPI presentation rules. | Keep two audit trails: one for the ESRS materiality assessment and one for taxonomy eligibility, alignment, KPI calculations, and template presentation. The same CapEx or OpEx item may be relevant to both, but the tests are different. | [Commission Delegated Regulation (EU) 2023/2772](https://data.europa.eu/eli/reg_del/2023/2772/oj?ref=sorena.io) - Defines double materiality for ESRS reporting.

Some ESRS taxonomy datapoints also identify relationships between significant CapEx or OpEx disclosures and taxonomy KPI or CapEx-plan information. | For non-financial undertakings, Article 8 KPI disclosures use turnover, capital expenditure, and operating expenditure. Financial undertakings have separate KPI methodologies and templates. | Finance, sustainability, and consolidation teams should reconcile taxonomy KPI inputs to ESRS financial links instead of pasting taxonomy percentages into ESRS tables without explanation. | [Commission Delegated Regulation (EU) 2023/2772](https://data.europa.eu/eli/reg_del/2023/2772/oj?ref=sorena.io) - Contains ESRS disclosure requirements and application requirements that connect sustainability disclosures to financial information where required.

This prevents a taxonomy calculation from being over-read as a materiality conclusion. | [Commission Delegated Regulation (EU) 2023/2772](https://data.europa.eu/eli/reg_del/2023/2772/oj?ref=sorena.io) - Supports keeping ESRS evidence tied to sustainability statement disclosures.

Quote: "key performance indicators" ### Practical decision rule - Use CSRD and ESRS when the facts match the left-side scope, trigger, and evidence rows. - Use EU Taxonomy Article 8 when the facts match the right-side scope, trigger, and evidence rows. - Reuse controls only where the comparison rows show the same actor, obligation, timing, and evidence basis. ## When this comparison is useful This page is relevant when the same reporting project contains both ESRS sustainability disclosures and EU Taxonomy Article 8 KPI disclosures. The overlap is real: Article 8 disclosures sit inside sustainability reporting and are part of the digital reporting package, but the legal tests and templates are different. The most common failure is to merge the workstreams too early. ESRS materiality tells the company what sustainability matters and disclosures are material. Article 8 tells covered undertakings how to disclose taxonomy eligibility, alignment, and KPIs for economic activities under the taxonomy rules. - Keep the ESRS materiality assessment separate from the taxonomy activity-mapping file. - Reconcile CapEx and OpEx references where ESRS climate disclosures and Article 8 KPI disclosures use related finance data. - Confirm whether the undertaking is non-financial or financial before selecting Article 8 KPI templates. - Treat XBRL tagging as a reporting-output step, not as the source of the legal disclosure obligation.
