Corporate Sustainability Reporting Directive (CSRD)

The cornerstone of CSRD reporting, requiring companies to evaluate sustainability from two distinct perspectives:

• Financial Materiality (Outside-In): How do climate change and social shifts affect the company's financial performance, development, and position?
• Impact Materiality (Inside-Out): How does the company's own operations and value chain impact people and the environment?

A topic is material if it meets the criteria from either perspective, fundamentally broadening the scope of what must be disclosed.

Companies must report in accordance with the European Sustainability Reporting Standards (ESRS) , a detailed set of 12 sector-agnostic standards developed by EFRAG. This replaces vague, self-selected frameworks with a prescriptive, standardized template.

• Cross-cutting Standards: ESRS 1 (General Requirements) and ESRS 2 (General Disclosures) are mandatory for all.
• Topical Standards: Cover Environment (E1-E5), Social (S1-S4), and Governance (G1).
• Mandatory Data Points: Each standard specifies exact quantitative and qualitative data points that must be reported.

All sustainability information must be prepared in a machine-readable XHTML format and digitally tagged using a dedicated XBRL taxonomy. This requirement:

• Forces companies to structure their sustainability data with the same rigor as financial statements.
• Enables automated analysis and comparison by investors, regulators, and data aggregators.
• Integrates sustainability data into the European Single Access Point (ESAP) , a public digital platform for corporate information.

The CSRD mandates third-party assurance of reported sustainability information, moving it from a marketing exercise to an audited compliance function.

• Initial Phase: Companies must obtain limited assurance from a statutory auditor or independent assurance services provider.
• Future Trajectory: The directive sets a clear pathway to evolve to reasonable assurance—the same level of scrutiny applied to financial audits—once the European Commission adopts assurance standards.

Reporting obligations extend beyond the company's own legal boundaries to encompass the entire upstream and downstream value chain. Companies must disclose material impacts, risks, and opportunities connected to their:

• Upstream: Suppliers, sourcing, and logistics partners.
• Downstream: Product use, end-of-life treatment, and customer relationships.

Transitional provisions allow for value chain data gaps to be explained using proxy data for the first three years if primary data is unobtainable.

The CSRD dramatically expands the number of companies required to report from approximately 11,700 under the NFRD to an estimated 50,000+ entities across the EU and beyond.

• Large Undertakings: All large companies meeting two of three criteria: >250 employees, >€50M net turnover, or >€25M balance sheet.
• Listed SMEs: Small and medium-sized enterprises on regulated markets, with a simplified reporting standard and an opt-out until 2028.
• Non-EU Companies: Ultimate parent companies with >€150M EU turnover and a qualifying EU branch or subsidiary must file a separate sustainability report.
