On 6 May 2026, the European Commission published the revised ESRS for public consultation, open until 3 June 2026. The substantive choices have been made, and they make reporting considerably simpler: over 60% fewer mandatory data points, a reporting burden more than 70% lower, and greater freedom to determine what is relevant. For Wave 2 companies, this means the rules of the game are settled and financial years 2025 and 2026 are crucial to prepare for the mandatory reporting on financial year 2027.
EFRAG delivered its technical advice on the European Sustainability Reporting Standards (ESRS) in December 2025, and the European Commission has developed this into a final proposal. The simplifications go beyond fewer data points; they also affect how and what you report. What exactly do the revised ESRS change? And what remains intact despite all the amendments?
The ESRS are being explicitly recast as a “fair presentation framework”. A sustainability report is no longer a tick-box exercise but must give a faithful overall picture of material impacts, risks and opportunities. This shift drives all the other changes: fewer prescribed data points, more room for independent judgement, and a report evaluated on coherence and relevance rather than on completeness.
The revised ESRS clarify that information must be usable for decision-making by users in general – not for the specific questions of all individual users or stakeholders. Companies may now work top-down, starting from the business model, strategy and value chain, to identify which topics and IROs are material, rather than systematically working through the full thematic list in ESRS 1.
Businesses may now decide for themselves whether to break down their materiality analysis by region or country; carrying out a detailed analysis at that level does not require reporting at the same level. Information may also be omitted where it is commercially sensitive or would seriously compromise the competitive position.
The revised ESRS also introduce structural reliefs:
The financial effects of sustainability risks may now be based on estimates, and revising those estimates in light of new information will not constitute a reporting error[KC1.1][DC1.2]. This is a welcome clarification, as organisations have found it difficult to quantify the financial effects of ESG risks with any precision.
There are also targeted refinements within the individual topical standards:
“Half of the two-year extension has passed. Restarting now is not optional. It is a necessity.”
Since the Omnibus of February 2025, many businesses have put their CSRD preparation on hold – as a result of the delay and in anticipation of the simplified standards. In the meantime, half of that two-year extension has passed and the revised ESRS are now available. The consultation can only lead to limited technical refinements; the substantive choices are fixed.
Restarting now is necessary to avoid falling behind in 2027. CSRD reporting cannot be done in the final months of the financial year. The foundations require thorough preparation, such as the double materiality assessment (DMA), setting up your data architecture, and establishing governance for reporting.
We therefore recommend that Wave 2 companies make the best possible use of the coming months:
This leaves you well prepared for your FY2027 reporting: final data collection, formal audit, publication of the first official report in 2028.
By starting now with the foundational building blocks, you gain a head start that will pay dividends when the first official report is due.
