Key Takeaways
- • The revised European Sustainability Reporting Standards (ESRS) and a new Voluntary European Sustainability Reporting Standard (VS) were published in the EU Official Journal on September 21, 2026, finalizing the bloc's streamlined sustainability reporting framework.
- • The simplified ESRS cut mandatory datapoints for in-scope CSRD companies by more than 60% and total datapoints by more than 70%, on top of previously raised CSRD applicability thresholds.
- • The new "value chain cap" limits the sustainability information larger CSRD reporters can demand from smaller value-chain companies to what is covered by the voluntary VS standard.
- • The European Commission estimates the changes could reduce reporting costs by more than 30% per company, though actual savings will depend on reuse of financial reporting systems, governance processes and value-chain complexity.
- • The simplified ESRS take effect November 10, 2026 and generally apply to financial years beginning on or after January 1, 2027, with early application permitted for "Wave-one" companies from financial years beginning January 1, 2026; the VS entered into force September 24, 2026.
Summary
The European Union's revamped sustainability reporting framework is now final. On September 21, 2026, the revised European Sustainability Reporting Standards (ESRS) and a new Voluntary European Sustainability Reporting Standard (VS) were published in the Official Journal, according to the source publication. The changes follow earlier increases to the financial thresholds that trigger compliance under the Corporate Sustainability Reporting Directive (CSRD) and are aimed at more proportionate sustainability reporting across Europe.
The revised ESRS reduce mandatory datapoints for in-scope undertakings by more than 60% and total datapoints by more than 70%. For companies that remain within CSRD scope, the smaller datapoint count is expected to ease the reporting burden. The VS provides a proportionate framework for smaller companies outside mandatory CSRD scope and introduces the "value chain cap," which restricts the sustainability information larger CSRD reporters may request from such smaller companies to the information covered by the VS. The source notes the cap is expected to ease reporting demands for entities outside CSRD scope as well.
On timing, the simplified ESRS enter into force on November 10, 2026 and generally apply to financial years beginning on or after January 1, 2027. "Wave-one" companies may elect to apply them early for financial years beginning on or after January 1, 2026. The VS entered into force on September 24, 2026. The European Commission estimates the changes could reduce reporting costs by more than 30% per company, although the source cautions that practical savings will depend heavily on how well companies can leverage existing financial reporting systems, governance processes and value-chain complexity.
Work continues on ESRS-40a, the standard for certain non-EU parent companies under the Accounting Directive. The European Financial Reporting Advisory Group (EFRAG) public consultation is scheduled to close October 31, 2026, after which EFRAG will analyze stakeholder feedback and deliver technical guidance to the Commission in early 2027. Approval of ESRS-40a is projected by summer 2027. Under the proposed scope, the standard would apply to non-EU parent companies with consolidated EU-based turnover exceeding €450 million in each of the last two consecutive financial years, and that have an EU subsidiary or branch with net turnover above €200 million in the preceding financial year. Some reporting suggests the final ESRS-40a may not require separate CSRD reporting at both the parent and EU undertaking level. Certain multinationals that expect to be scoped in at the parent level but not necessarily at the EU subsidiary level are already planning to report under ESRS-40a.
