# ESRS data point inventory workflow for CSRD reporting

Build an ESRS data point inventory that links disclosure requirements, materiality outcomes, evidence owners, XBRL tagging readiness, and assurance controls.

*CSRD* *ESRS inventory* *EU*

## ESRS data point inventory workflow

A workflow for turning ESRS disclosure requirements into an owned data-point register with materiality status, evidence links, and review controls.

Use it before drafting the sustainability statement, preparing XBRL tagging, or handing evidence to assurance reviewers.

An ESRS data point inventory is the bridge between the materiality assessment and the reported sustainability statement. It should identify each disclosure requirement or data point, record whether it is mandatory, material, conditional, voluntary, or omitted, name the evidence owner, and show how the item will be drafted, reviewed, tagged, and supported for assurance.

## Build the inventory from ESRS disclosure requirements

Start with EFRAG IG 3 and the adopted ESRS, not a blank spreadsheet. IG 3 explains that a data point is a separable piece of information required by ESRS disclosure requirements, and that one disclosure requirement can contain multiple data points. Treat each inventory row as a controlled reporting object, not as a loose topic label.

For each row, record the ESRS standard, disclosure requirement, paragraph or application requirement reference, data type, conditional wording, voluntary status, phase-in status if shown in the source material, and whether the row is a minimum disclosure requirement for policies, actions, metrics, or targets.

- Inventory field: ESRS standard and disclosure requirement, for example ESRS 2 IRO-1 or a topical disclosure requirement.
- Inventory field: data point description, paragraph reference, and data type such as narrative, numerical, Boolean, enumeration, or table.
- Inventory field: applicability marker for mandatory, subject to materiality, conditional, alternative, voluntary, or omitted.
- Inventory field: reporting boundary, consolidation level, value-chain input, and any disaggregation needed to avoid obscuring material information.
- Inventory field: drafting owner, source-system owner, evidence owner, reviewer, and final disclosure approver.

## Connect each data point to materiality conclusions

Do not mark a data point as out of scope just because a reporting team lacks data. The Commission Q&A states that ESRS 2 is mandatory for companies under CSRD scope, while other standards and individual disclosure requirements and data points are subject to materiality assessment. EFRAG IG 1 also explains that ESRS 2 cross-cutting disclosures are reported irrespective of the materiality assessment outcome.

For data points subject to materiality, the row should point to the material impact, risk, or opportunity, the threshold or qualitative criterion used, and the evidence supporting the conclusion. If a data point derived from SFDR, the Benchmarks Regulation, or the Capital Requirements Regulation is assessed as not material, record the explicit not-material treatment and where the table entry will appear in the sustainability statement.

- Gate: ESRS 2 and cross-cutting disclosures cannot be filtered out by a topical materiality conclusion.
- Gate: a topical data point is included when the related sustainability matter or information is material under the documented assessment.
- Gate: policies, actions, and targets need a response for the relevant minimum disclosure requirements when the undertaking reports them for a material matter.
- Gate: omitted metrics need a materiality basis, not a data-availability explanation.
- Gate: EU-legislation data points assessed as not material need explicit table treatment rather than silence.

## Add evidence ownership and assurance-ready controls

The inventory should show who can prove each disclosed fact. For quantitative data, name the source system, extraction logic, period, consolidation check, and reconciliation owner. For narrative data, name the policy, governance record, stakeholder input, management approval, or board material that supports the text.

EFRAG IG 1 notes that documentation can help governance bodies prepare ESRS 2 IRO-1 disclosures and help assurance providers perform their work. Translate that into controls: every high-risk row needs an evidence package, reviewer sign-off, change log, and clear treatment for estimates, restatements, and late evidence.

- Evidence field: source system or source document, extraction date, calculation owner, and reviewer.
- Evidence field: materiality assessment link, IRO identifier, threshold or criterion, and stakeholder or management input used.
- Evidence field: draft disclosure text, reviewer comments, approval date, and unresolved limitations.
- Control field: completeness check against IG 3 and the adopted ESRS source, including conditional and voluntary rows.
- Control field: consistency check between narrative claims, metrics, policies, actions, targets, and related financial statement line items where relevant.

## Prepare the inventory for XBRL tagging

The data point inventory is not the same as the ESRS XBRL taxonomy. EFRAG IG 3 explains that the human-readable data point list and the digital taxonomy differ for technical reasons, even though they are based on consistency. Use the inventory to structure disclosures early, then map each final disclosure to the taxonomy element or tagging treatment once the reporting format work starts.

For tagging readiness, add columns for taxonomy element, tag status, extension need, anchoring rationale, text-block scope, table handling, dimensions, units, period type, and duplicate-value checks. ESMA's ESEF consultation material describes marking up as using XBRL elements to label information in a human-readable annual report so that it is machine-readable.

- Tagging field: XBRL element or planned extension, with rationale when no core element fits.
- Tagging field: narrative text-block boundary, continuation risk, and whether multiple data points sit inside one integrated narrative disclosure.
- Tagging field: numeric unit, period, dimensional breakdown, and consistency with the visible report value.
- Tagging field: table mapping, line-item treatment, and any dimensions required by the taxonomy.
- Review gate: no final disclosure is approved until the owner confirms that the human-readable wording and machine-readable tag tell the same story.
