Austria Sustainability Reporting Act: Austria NaBeG (CSRD): Audited ESRS Reporting and Double Materiality

Summary

Austria’s NaBeG implements CSRD and turns sustainability reporting into a legally controlled, auditable disclosure regime based on ESRS and double materiality. Companies must produce evidence-grade ESG data, integrate it into corporate reporting, and undergo external assurance. Compliance failures typically stem from governance and evidence gaps: undocumented materiality decisions, inconsistent reporting boundaries, and unverifiable metrics. Treat NaBeG readiness as a finance-grade controls project, not an ESG communications task.

What’s Required

Austria’s Nachhaltigkeitsberichtsgesetz (NaBeG) implements the EU Corporate Sustainability Reporting Directive (CSRD) in national law and makes sustainability reporting a regulated corporate reporting and assurance duty. Core requirements include:

  • ESRS-based sustainability statement integrated into corporate reporting (content, metrics, targets, governance, risks, and impacts).

  • Double materiality assessment with documented methodology and evidence trail (a recurring enforcement focus across the EU).

  • External assurance of sustainability reporting (initially limited assurance under CSRD design).

  • Expanded disclosure discipline: consistency with financial statements, controlled boundaries, and audit-ready data lineage.

Important Deadlines

  • 21 Jan 2026: NaBeG approved by Austria’s Nationalrat.

  • Early Feb 2026 (expected): Bundesrat decision.

  • By the end of Feb 2026 (expected): publication in Federal Law Gazette; entry into force the day after publication.

  • Reporting phase-in follows CSRD categories and timelines (EU-level).

Current Status

NaBeG has been adopted by the Nationalrat and is progressing toward Bundesrat and gazette publication.

Penalties for Non-Compliance

NaBeG is designed as an enforceable corporate reporting law: typical consequences include administrative sanctions, correction orders, and heightened auditor/regulator intervention (exact sanctioning pathways depend on the implementing provisions and related corporate law amendments).

Examples of Known Violations

  • Missing/late sustainability statement in management reporting.

  • Double materiality conclusions are not defensible vs business reality (poor documentation, unclear thresholds).

  • Assurance failure due to weak evidence, inconsistent boundaries, or uncontrolled spreadsheets.
