What’s Required

Decree 18/2023 marks Italy’s first step in transposing the EU Corporate Sustainability Reporting Directive (CSRD).
It updates national rules to prepare large companies and groups for ESRS-aligned sustainability reporting.

Obligations include:

  • Expansion of the number of companies required to report sustainability information.

  • New governance and internal-control requirements for sustainability reporting.

  • Preparation for mandatory external assurance of sustainability disclosures.

  • Alignment with the European Sustainability Reporting Standards (ESRS).

Important Deadlines

  • Applies progressively from 2024–2026, depending on company size and EU thresholds.

  • The full ESRS application begins with financial years starting in 2025 for the largest companies.

Current Status

  • The decree is in force but represents only the first stage; Italy is preparing a full Business Sustainability Information Law to complete CSRD transposition.

  • Supervisors encourage early alignment with ESRS due to the upcoming mandatory assurance.

Penalties for Non-Compliance

  • Sanctions will mirror existing Italian corporate reporting penalties and will include fines for incomplete, missing, or misleading sustainability information.

  • Directors may incur liability for severe or repeated breaches.

Examples of Known Violations

  • No public violations yet, as implementation is ongoing and ESRS reporting has not fully begun.
