EU CSRD Scope, ESRS reporting and assurance guide
Use this artifact to frame Corporate Sustainability Reporting Directive work around the reporting entity, the management-report sustainability statement, ESRS disclosures, double materiality, upstream and downstream value-chain information, assurance, and digital reporting preparation.
CSRD reporting is not only an annual ESG narrative. The useful starting point is a source-linked reporting model: which undertaking reports, which ESRS topics and datapoints are material, which value-chain estimates are needed, which Article 8 Taxonomy disclosures connect to the report, and which controls make the sustainability statement assurance-ready.

What this CSRD hub helps you confirm
Reporting scope and purpose
Separate the entity or group reporting boundary from the sustainability matters users need to understand: impacts on people and the environment, and how sustainability matters affect development, performance, and position.
ESRS disclosure model
Use ESRS 1, ESRS 2, topical ESRS, EFRAG materiality guidance, and the ESRS datapoint list to connect IROs, policies, actions, targets, metrics, and narrative disclosures.
Assurance and filing evidence
Prepare records that show materiality judgments, value-chain methods, data lineage, Article 8 Taxonomy inputs, digital-tagging decisions, and review sign-offs before the report is assured.

Quick scan
CSRDScope first
Confirm whether the undertaking reports under the CSRD-amended Accounting Directive, then document the group boundary, exemptions, and any third-country reporting question.
Materiality to datapoints
Run double materiality, identify impacts, risks, and opportunities, and map them to ESRS disclosures and datapoints instead of drafting from generic topic headings.
Evidence before publication
Keep calculation files, source-system extracts, supplier or estimate methods, taxonomy KPI support, assurance requests, and tagging decisions tied to each disclosure.
Use the topic guides for applicability, double materiality, ESRS data points, value-chain information, Article 8 Taxonomy links, assurance readiness, and digital reporting preparation.

Next step
Turn CSRD scope and ESRS reporting into accountable evidence work
Use this CSRD hub as the shared reference for legal entity scope, ESRS materiality, value-chain requests, sustainability-statement drafting, Article 8 Taxonomy inputs, assurance preparation, and digital-reporting decisions.
What this unlocks
- Create a scope record for each undertaking or group boundary, including exemptions, publication route, and any third-country reporting dependency.
- Maintain a double-materiality file that links stakeholder input, impact materiality, financial materiality, IROs, and ESRS disclosure conclusions.
- Track ESRS datapoints with source systems, owners, calculation methods, value-chain estimates, controls, and review status.
- Keep assurance requests, management-report review evidence, Article 8 Taxonomy support, and XBRL or ESEF tagging decisions connected to the same disclosure inventory.
Recommended route
Open ESG Compliance
Manage CSRD scope, ESRS disclosure owners, value-chain evidence, and assurance requests in one sustainability reporting workflow.
Supporting route
Open SSOT
