The European Central Bank (“ECB“) has issued an ECB staff opinion on the revised European Sustainability Reporting Standards (“ESRS“) and its impact on its regulatory mandates (“Opinion“). The Opinion sets out the ECB’s technical assessment of EFRAG’s draft revised ESRS in the context of the Commission’s broader efforts to streamline corporate sustainability reporting requirements. The Opinion is available at this link.

The Opinion focused on the ESRS most relevant for the ECB’s mandates – ESRS 1 (General Requirements), ESRS 2 (General Disclosures), ESRS E1 (Climate Change) and ESRS E4 (Biodiversity and Ecosystems) – as these disclosures feed into the identification and assessment of climate- and nature-related financial risks. The ECB welcomed the significant simplification achieved (including clearer separation between disclosure requirements and application requirements, and improved visibility of the materiality-of-information filter), but they highlight three priority concerns to preserve decision-useful transparency. These include:

• the cumulative impact of permanent reliefs, phase-ins and exemptionsthat could reduce data availability and comparability;
• potential loss of interoperabilitywhere new reliefs go beyond IFRS/ISSB; and

areas requiring clarification to ensure the revised ESRS remain workable for meaningful disclosures by banks, notably regarding value-chain relevance.

Finally, the Opinion flagged wider implementation issues: the importance of prompt assurance standards for auditors, timely publication of non-mandatory illustrative guidance, careful handling of an expanded role for voluntary standards (to mitigate greenwashing risks), and the need for regular reviews so the EU reporting framework remains fit for purpose as methodologies and risk conditions evolve.
