This document presents an official opinion from EIOPA regarding the European Commission's efforts to simplify and streamline the European Sustainability Reporting Standards (ESRS). While the authority generally supports reducing the regulatory burden for companies, it expresses specific concerns that excessive reporting reliefs could decrease the quality and comparability of essential data. EIOPA emphasizes that maintaining high‑quality disclosures is vital for insurance and pension sectors to accurately assess sustainability risks and fulfill their roles as institutional investors. The text highlights the importance of interoperability with international standards, such as IFRS, and ensures that new reporting rules remain consistent with existing EU legislation like Solvency II and the SFDR. Ultimately, the source advocates for a balanced approach where simplification does not compromise the transparency or stability of the financial system.
