Overview

The Corporate Sustainability Reporting Directive changes EU sustainability reporting by extending reporting beyond the old non-financial reporting population and requiring companies in scope to report under European Sustainability Reporting Standards. Use this FAQ hub to find the specific answer behind a CSRD decision: entity scope, first reporting year, ESRS datapoint inventory, double materiality, value chain data, assurance, digital filing, or EU Taxonomy Article 8 reporting.

Question 1

Which CSRD FAQ should a company read first?

Start with scope and reporting wave questions before building an ESRS workplan. CSRD applies through the Accounting Directive framework to large undertakings, listed undertakings other than micro-undertakings, parent undertakings of large groups, and certain third-country undertakings with significant EU activity. The exact answer depends on the legal entity, group structure, listing status, EU turnover, and whether a subsidiary or branch has publication duties.

After scope is confirmed, use the ESRS-focused FAQ modules to decide how the sustainability statement is built: ESRS 1 and ESRS 2 set the general reporting architecture, topical standards apply through double materiality, and the data-point inventory translates material disclosures into collectable reporting evidence.

  • Scope questions: direct CSRD coverage, listed SME status, group reporting, third-country group publication, and possible exemptions.
  • Reporting wave questions: first financial year, report publication timing, stop-the-clock or simplification status in the current source set, and whether older planning dates need to be rechecked.
  • ESRS questions: ESRS 1 general requirements, ESRS 2 general disclosures, topical ESRS, material impacts, risks, opportunities, and datapoint inventory.
  • Execution questions: value chain estimates, Taxonomy Article 8 KPIs, assurance evidence, and XBRL or Inline XBRL tagging readiness.
Question 2

How do CSRD and ESRS fit together?

CSRD is the legal reporting framework; ESRS are the standards used to prepare the sustainability statement. Commission Delegated Regulation (EU) 2023/2772 adopted the first set of sector-agnostic ESRS, including ESRS 1, ESRS 2, environmental standards, social standards, and ESRS G1 for business conduct.

The practical mistake is to treat every ESRS datapoint as automatically reportable. ESRS reporting starts from double materiality: ESRS 2 general disclosures are always central, while topical disclosures depend on the undertaking's material impacts, risks, and opportunities. If climate change is assessed as not material, ESRS requires a detailed explanation for that conclusion.

  • ESRS 1 explains the general requirements, including double materiality, reporting boundaries, value chain, time horizons, and preparation principles.
  • ESRS 2 requires general disclosures across governance, strategy, impact, risk and opportunity management, and metrics and targets.
  • Topical ESRS disclosures are selected through materiality, with special handling when climate change is assessed as not material.
  • EFRAG IG 3 can help convert disclosure requirements into a datapoint inventory, but the adopted ESRS remain the authoritative source.
Question 3

What should the double materiality and value chain FAQs answer?

A useful CSRD materiality answer should identify impacts, risks, and opportunities, then explain whether the matter is material from the impact perspective, the financial perspective, or both. ESRS defines impact materiality around actual or potential impacts on people or the environment, including impacts connected with the undertaking's own operations and upstream and downstream value chain.

Value chain answers should not demand perfect supplier data on day one. The CSRD text includes a first-three-years provision for cases where not all necessary value chain information is available: the undertaking must explain the efforts made, why information could not be obtained, and plans to obtain it in the future. The Commission FAQ page also highlights clarification on when estimates may be used rather than collecting information from suppliers or partners.

  • For materiality, retain the topic list considered, stakeholder inputs, impact severity and likelihood logic, financial magnitude and likelihood logic, thresholds, and final IRO conclusions.
  • For value chain, retain requests sent, supplier or partner responses, estimation methods, missing-data reasons, and the plan to improve collection.
  • For SMEs in the value chain, check that information requests do not exceed the level of sustainability information that ESRS SME standards are designed to support.
  • For non-material topics, keep the rationale; for climate change, expect a more detailed explanation if ESRS E1 is omitted.
Recommended next step

Build a CSRD evidence file before drafting the sustainability statement

Use the CSRD FAQ modules to connect entity scope, ESRS materiality, value chain data, assurance evidence, digital tagging, and Article 8 KPI support before reporting starts.

Question 4

How should teams handle assurance and digital tagging under CSRD?

Treat assurance and digital tagging as report-production requirements, not after-the-fact formatting. CSRD requires an assurance opinion on sustainability reporting, initially based on limited assurance, covering compliance with the Directive, ESRS, the process for identifying reported information, digital markup, and Taxonomy Article 8 reporting where applicable.

For digital reporting, CSRD requires the management report or consolidated management report to be prepared in the electronic reporting format specified under the ESEF framework and to mark up sustainability reporting once the relevant electronic reporting format is determined. EFRAG's ESRS Set 1 XBRL Taxonomy material explains the taxonomy work, while ESMA is responsible for tagging rules that are to be adopted through the ESEF regulatory process.

  • Assurance file: ESRS mapping, materiality assessment, data controls, source systems, management review, estimates, value chain evidence, and unresolved limitations.
  • Digital filing file: report boundary, ESEF format responsibilities, ESRS taxonomy mapping, tagged datapoints, validation results, and reviewer sign-off.
  • Taxonomy Article 8: keep eligibility, alignment, KPI calculations, assumptions, and cross-references aligned with the sustainability statement.
  • Do not cite ISSA 5000 as the EU CSRD assurance rule itself; use it as relevant sustainability assurance context where the engagement standard is selected or referenced.
