EU CSRD: Corporate Sustainability Reporting Enters a New Dimension

From NFRD to CSRD: A Fundamental Upgrade

The Non-Financial Reporting Directive (NFRD), which had been in force since 2018, applied to approximately 11,700 large public-interest entities in the EU. While a step forward, the NFRD was widely criticized for its lack of standardized reporting requirements, limited scope, and inadequate comparability across companies and sectors.

The Corporate Sustainability Reporting Directive (CSRD), formally published in the EU Official Journal on December 16, 2022 and entering into force on January 5, 2023, represents a comprehensive overhaul of this framework. It dramatically increases both the number of companies subject to mandatory sustainability reporting and the quality and comparability of the information required.

Expanded Scope: Up to 50,000 Companies

The CSRD applies to:

• All large EU companies (meeting at least two of: >250 employees, >EUR 40M turnover, >EUR 20M total assets) — approximately 49,000 companies
• All companies listed on EU regulated markets (except micro-enterprises) — approximately 3,500 additional companies
• Non-EU companies with significant EU operations (net turnover >EUR 150M in the EU) — estimated at approximately 10,000 companies from 2028

The European Sustainability Reporting Standards (ESRS)

A central feature of the CSRD is the mandatory use of the European Sustainability Reporting Standards (ESRS), developed by the European Financial Reporting Advisory Group (EFRAG) and adopted by the European Commission. The ESRS cover:

• Cross-cutting standards: General reporting requirements and general disclosures
• Environmental standards: Climate change (ESRS E1), pollution (E2), water and marine resources (E3), biodiversity and ecosystems (E4), resource use and circular economy (E5)
• Social standards: Own workforce (S1), workers in the value chain (S2), affected communities (S3), consumers and end-users (S4)
• Governance standards: Business conduct (G1)

Double Materiality: A New Standard for Disclosure

The most conceptually significant innovation of the CSRD is the principle of double materiality. Companies must assess and report on sustainability issues from two perspectives simultaneously:

• Impact materiality: The company's actual or potential significant impacts on people and the environment (outside-in perspective)
• Financial materiality: How sustainability factors create material risks or opportunities for the company's financial performance (inside-out perspective)

Double materiality reflects the recognition that sustainability is not merely a risk management question — it is also a question of a company's role and responsibilities within broader society and the natural world.

Limited Assurance and Progressive Requirements

CSRD-mandated reports must be subject to limited assurance from an accredited auditor or other assurance service provider, with a pathway toward reasonable assurance in future years. Reports must be included in the management report and published in a machine-readable format to enable digital access and analysis.
