On 6 May 2026, the European Commission (EC) published a draft delegated act containing the simplified European Sustainability Reporting Standards (revised ESRS) and opened a four-week period for comment that closes on 3 June 2026. This is one of the final steps in completing the EC’s February 2025 ‘Omnibus’ package intended to simplify EU sustainability reporting rules.
The European Commission’s draft simplified ESRS marks a practical shift to simplify EU sustainability reporting rules. With consultation open until 3 June 2026 and mandatory application from FY2027 (early adoption in FY2026 permitted based on current draft), Irish in-scope companies should now review their reporting roadmaps and consider how to embed these changes.
On 6 May 2026, the European Commission (EC) published a draft delegated act containing the simplified (revised) European Sustainability Reporting Standards (ESRS) and opened a four-week consultation running until 3 June 2026. The EC also published a separate draft delegated act containing a sustainability reporting standard for voluntary use (voluntary standard), open for comment over the same period. This voluntary standard will replace the previous Voluntary Sustainability Reporting Standard for non-listed SMEs (VSME).
Although there had been discussion over the past few months about potential changes to the requirements to align closer with the International Sustainability Standards Board (ISSB) framework, the draft revised ESRS did not add any additional requirements in this area.
This is one of the final steps in completing the EC’s February 2025 “Omnibus” package intended to simplify EU sustainability reporting rules issued as result of the European Green Deal.
For Irish businesses preparing for CSRD reporting, the message is clear: the policy direction is simplification and greater usability- but the compliance clock is still running, and implementation decisions made in 2026 will shape cost, data burden and assurance readiness for years.
The EC’s revised ESRS are based on EFRAG’s technical advice delivered on 3 December 2025. EFRAG’s brief targeted reducing the number of mandatory datapoints, clarifying unclear provisions, simplifying the structure and presentation of the standards, and enhancing interoperability.
The EC states it made targeted modifications to EFRAG’s advice “with the primary aim of facilitating the application of the standards by clarifying certain provisions and granting additional flexibilities” for entities within the scope of CSRD.
In preparing the revised ESRS, the EC considered input from EU Supervisory Authorities, including the European Securities and Markets Authority (ESMA), the European Banking Authority (EBA), the European Central Bank (ECB), and the European Insurance and Occupational Pensions Authority (EIOPA), as well as from a range of other stakeholders.
The draft delegated act includes the 12 revised ESRS, alongside revised acronyms and a glossary of terms, supported by an explanatory memorandum setting out the principal modifications the EC made to EFRAG’s technical advice.
Key changes from EFRAG’s technical advice that would be expected to have potentially significant impact include the following:
“The draft simplified ESRS is a signal to focus on decision-useful disclosures and workable data collection - without losing sight of governance and assurance readiness. Irish businesses should use this window to simplify with confidence, not pause.”
Fiona Gaskin, Head of Sustainability Reporting and AssuranceThe consultation on the draft delegated acts runs until 3 June 2026. The EC has indicated it intends to adopt the delegated acts as soon as possible after the consultation closes.
The delegated acts will then be subject to a two-month scrutiny period by the European Parliament and the Council of the European Union (which may be extended to four months). They will enter into force three days after publication in the Official Journal of the European Union, and no transposition into Member State law is required.
The delegated act containing the revised ESRS will apply for financial years beginning on or after 1 January 2027, with early application permitted for financial years beginning in 2026 based on the current draft.
For Irish decision-makers, the most useful way to treat the draft is as a near-final direction of travel and a prompt to de-risk implementation choices:
Reconfirm your emissions boundary approach and document the rationale, controls and audit trail you will use to evidence consistency over time.
Revisit value-chain data strategy (what you request, from whom, how often, and on what basis) and ensure it is proportionate and contractually feasible.
Prepare for assurance-readiness by aligning sustainability reporting governance, internal controls and accountability with financial reporting discipline.
As the simplified ESRS move through consultation and scrutiny, the organisations that respond best will be those that quickly turn policy change into implementation.
