CSRDScope first
Confirm whether the undertaking exceeds the current CSRD scope thresholds, then document the group boundary, exemptions, financial-year trigger, and any third-country reporting route.
Materiality to datapoints
Run , identify impacts, risks, and opportunities, and map them to ESRS disclosures and datapoints instead of drafting from generic topic headings.
Evidence before publication
Prepare the as part of the management report, with calculation files, source-system extracts, supplier or estimate methods, taxonomy KPI support, assurance requests, and tagging-readiness decisions tied to each disclosure. Sustainability markup is not required until the ESEF marking rules are adopted.
Follow the grouped guides in order: current scope and status, ESRS reporting decisions, implementation evidence, deadlines and assurance, then framework comparisons.

What this CSRD hub helps you confirm
Reporting scope and purpose
Separate the entity or group reporting boundary from the sustainability matters reported. Directive (EU) 2026/470 narrows the main Articles 19a and 29a scope from financial years beginning in 2027, so earlier CSRD size tests are not a current-scope shortcut.
ESRS disclosure model
Use the ESRS edition that applies to the reporting year. The Commission adopted revised ESRS on 3 July 2026, but they remain under Parliament and Council scrutiny; until they enter into force, do not replace the applicable 2023 ESRS with the revised text.
Assurance and filing evidence
Prepare records that show materiality judgments, value-chain methods and cap decisions, data lineage, Article 8 Taxonomy inputs, digital-tagging decisions, and review sign-offs before the report is assured.

Start with the legal entity, group boundary, and financial year. Then test the turnover-and-employee thresholds, the optional 2025-2026 Member State exemption, the non-EU route, ESRS materiality, value-chain limits, Article 8 Taxonomy disclosures, , and the current digital-markup status.
CSRD Timeline
Key legal dates for CSRD, ESRS, and digital reporting work
Use the cited timeline to distinguish the original CSRD waves, the enacted Stop-the-Clock delay, Directive (EU) 2026/470, the 2023 ESRS now in force, the revised ESRS adopted on 3 July 2026 but still under scrutiny, assurance milestones, third-country reporting, and ESEF/XBRL developments.

Next step
Turn CSRD scope and ESRS reporting into accountable evidence work
This CSRD hub is 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
