The Corporate Sustainability Reporting Directive (Directive 2022/2464)
The Corporate Sustainability Reporting Directive (CSRD), formally Directive (EU) 2022/2464, is the European Union’s comprehensive framework for corporate sustainability reporting. Adopted on 28 November 2022, the CSRD fundamentally revises and expands the Non-Financial Reporting Directive (NFRD, Directive 2014/95/EU), extending the scope of reporting obligations, introducing mandatory European Sustainability Reporting Standards (ESRS), requiring assurance of reported information, and mandating digital tagging of reports. The CSRD is a cornerstone of the EU’s sustainable finance agenda and the European Green Deal, following the logic that transparent, comparable, and reliable sustainability information is necessary to redirect capital flows toward sustainable economic activities.
Scope and Application Timeline
The CSRD applies to a significantly broader range of companies than the NFRD. The Directive applies to: large undertakings meeting at least two of three criteria (250 employees, €40 million net turnover, €20 million total assets); small and medium-sized undertakings with securities listed on EU regulated markets (except micro-undertakings); non-EU undertakings generating a net turnover exceeding €150 million in the EU with at least one subsidiary or branch meeting certain thresholds; and parent undertakings of large groups. The scope expands from approximately 11,700 companies under the NFRD to approximately 50,000 under the CSRD.
The reporting obligations are phased in progressively. Companies already subject to the NFRD must report from financial year 2024 (reports published in 2025). Large companies not currently subject to the NFRD must report from financial year 2025. Listed SMEs must report from financial year 2026 with an opt-out until 2028. Non-EU undertakings meeting the turnover threshold must report from financial year 2028.
European Sustainability Reporting Standards
The CSRD mandates reporting in accordance with European Sustainability Reporting Standards (ESRS) developed by the European Financial Reporting Advisory Group (EFRAG) in its new role as the Commission’s technical adviser for sustainability reporting. The Commission adopted the first set of ESRS as delegated regulations on 31 July 2023: ESRS 1 (General Requirements) and ESRS 2 (General Disclosures), together with ten topical standards covering environmental matters (ESRS E1–E5: climate change, pollution, water and marine resources, biodiversity and ecosystems, resource use and circular economy), social matters (ESRS S1–S4: own workforce, workers in the value chain, affected communities, consumers and end users), and governance matters (ESRS G1: business conduct).
Double Materiality
The CSRD is built on the principle of double materiality, which ESRS 1 operationalises as the central determinant of reporting scope. Double materiality requires companies to report both on how sustainability matters affect their financial performance and prospects (financial materiality, or “outside-in” perspective) and on how their activities impact people and the environment (impact materiality, or “inside-out” perspective). A sustainability matter meets the double materiality criterion if it is material from either the impact or the financial perspective. Impact materiality is assessed by reference to the scale, scope, and remediability of impacts. Financial materiality is assessed by reference to the magnitude and likelihood of risks and opportunities that affect enterprise value.
Assurance of Sustainability Information
The CSRD introduces mandatory assurance of sustainability reporting, moving from voluntary or no assurance under the NFRD to a graduated assurance regime. Member States must require statutory auditors or independent assurance services providers to express an opinion on the conformity of sustainability reporting with the ESRS and on compliance with the reporting requirements, including the process of identifying reported information. Limited assurance is required initially, with a view to moving to reasonable assurance after a separate Commission assessment of the feasibility and cost implications. Assurance must cover the electronic tagging of information.
EFRAG’s Role
The European Financial Reporting Advisory Group (EFRAG) plays a central role in the CSRD architecture. The Commission appointed EFRAG as the technical adviser for the development of draft ESRS, which the Commission adopts as delegated acts. EFRAG’s Sustainability Reporting Board, composed of experts from preparers, users, auditors, civil society, and national standard-setters, oversees the standard-setting process. EFRAG also develops sector-specific standards, standards for listed SMEs, and standards for non-EU undertakings, in consultation with relevant stakeholders.
Digital Tagging and the Single Electronic Format
The CSRD requires sustainability reporting to be prepared in the single electronic reporting format (Article 5 of Directive 2013/50/EU) and tagged in accordance with the digital taxonomy established by ESMA. Companies must mark up sustainability information using XHTML format and iXBRL tagging, enabling machine-readability and comparability across the EU. The tagged information feeds into the European Single Access Point (ESAP), which makes company information publicly available through a single digital platform.
Enforcement and Penalties
Member States must establish effective, proportionate, and dissuasive penalties for infringements of the CSRD transposition measures. Penalties must include administrative fines, public statements identifying the responsible person or entity, and injunctions requiring cessation of infringements. National competent authorities, including competent authorities designated under the Transparency Directive and national audit oversight bodies, are responsible for supervision and enforcement in coordination with ESMA.
