CSRD and ESRS Reporting Checklist

Start with the legal reporting entity and reporting year before drafting disclosures. For financial years beginning in 2027, document whether the undertaking or parent group exceeds both EUR 450 million net turnover and 1,000 average employees under Directive (EU) 2026/470, plus any exemption and national transposition rule. For financial years beginning in 2025 or 2026, check whether the Member State used the optional exemption for an undertaking below either new threshold.

For group reporting, align the sustainability statement with the reporting undertaking used for the financial statements. Where a subsidiary exemption is relied on, record the parent undertaking, registered office, report links, assurance link, and the exemption reference required by the Accounting Directive.

The disclosure inventory should separate always-required ESRS 2 general disclosures from topical disclosures that depend on the double materiality assessment. It should also identify EU-law datapoints and Taxonomy Regulation disclosures that need explicit handling.

Record the ESRS legal version used for the report. The Commission adopted revised ESRS on 3 July 2026, but they remain under Parliament and Council scrutiny and do not apply until that process ends. Do not mix the revised text into a report still governed by Delegated Regulation (EU) 2023/2772.

Do not treat a topic as excluded just because no metric is currently available. The checklist should require a recorded materiality conclusion, the affected disclosure requirements, any omission rationale allowed by ESRS, and the owner responsible for evidence.

A CSRD checklist should make the materiality assessment auditable. Keep the method, stakeholder inputs, thresholds, evidence sources, and impacts, risks and opportunities (IRO) register together so reviewers can trace why each sustainability matter was included, excluded, aggregated, or disaggregated.

Value-chain work should focus on material upstream and downstream impacts, risks, and opportunities rather than every supplier or customer. Where estimates, proxies, or sector averages are used, keep the basis and limitation visible in the evidence file.

Assurance readiness should be built before the report is drafted. The Accounting Directive requires an assurance opinion on sustainability reporting, and the auditor or permitted assurance provider must be able to test compliance with ESRS, the materiality process, Taxonomy Regulation reporting where applicable, and digital markup once the marking rules apply.

The checklist should therefore include control owners, source systems, review evidence, version control, and unresolved limitations for each material disclosure.

Article 29d links sustainability reporting to the ESEF electronic format and future markup, but Directive (EU) 2026/470 states that undertakings are not required to mark up sustainability reporting until the marking rules are adopted through Delegated Regulation (EU) 2019/815. Treat the current work as readiness unless an applicable final rule says otherwise.

Before publication, confirm that the report structure, labels, narrative disclosures, tables, units, periods, and cross-references can be tagged consistently with the applicable ESRS taxonomy and ESEF rules when those rules apply. Do not report a successful readiness test as a completed statutory XBRL filing.
