Following the announcement last year of the Omnibus simplification, the European Financial Reporting Advisory Group (EFRAG) released updates in November to the European Sustainability Reporting Standards (ESRS). This prompted many sustainability teams to revisit the time-intensive work they put into structuring double materiality assessments, mapping data points and negotiating internal alignment.
Market reactions quickly split. Some saw the changes as a regulatory retreat. Others welcomed the simplification. Most practitioners faced uncertainty about what had structurally changed.
Simplification undoubtedly occurred. The key takeaway: while reporting requirements are lighter, it is crucial to determine whether the ESRS’s core logic has shifted or remained the same.
What actually changed
The quantitative reduction is significant. Mandatory datapoints were reduced by more than 60%, while the broader disclosure universe contracted substantially after voluntary elements were removed. Scope thresholds were raised, concentrating reporting obligations on larger entities. In addition, relief mechanisms were introduced for value chain data, structural changes and the application of undue cost or effort.
The double materiality assessment process was streamlined, with the introduction of an explicit information materiality filter. Companies now structurally disclose only what is considered material. The removal of prescriptive appendices increased reliance on professional judgment.
At the same time, interoperability with the International Sustainability Standards Board (ISSB) standards was strengthened. Concepts such as fair presentation and decision-useful information are now more explicitly embedded and aligned with IFRS S1.
The new ESRS is leaner in structure. However, its expectations remain rigorous as it reallocates the burden of reporting without reducing its importance.
What persists and what becomes more explicit
Despite a reduced volume, double materiality remains central as companies must still assess the impacts, risks and opportunities while applying a materiality lens to disclosures.
What has changed is the structure of selectivity
The explicit information materiality filter reinforces the need to report only data that is considered material to the business. Rather than focusing on broad coverage followed by justification, the framework embeds relevance from the start, shifting from comprehensiveness to focused filtering.
The need for fair presentation is reinforced and is more closely aligned with global reporting logic. Decision-usefulness is prioritized as a criterion for removing less relevant data points.
The ESRS foundation remains recalibrated for proportionality, coherence and decision-usefulness.
The real shift: From coverage to judgment
The most meaningful change is behavioral, not numerical.
Under the original ESRS, teams found that burdens increased with scale as they were tasked with demonstrating coverage across numerous datapoints. The main risk was omission.
Now the risk profile shifts to defensibility with revised standards, fewer required disclosures, and explicit filters. The guidance emphasizes proportionality and reasonable evidence, clarifying that exhaustive disclosure is unnecessary. Coherent reasoning now prevails.
The responsibility moves from managing volume to substantiating selectivity. Sustainability teams will have to explain what is and is not considered material. This requires stronger documentation and internal alignment. It also calls for cross-functional dialogue, particularly with finance and risk.
The checklist is shorter. The demand for rigor remains. And the quality of judgment now outweighs the quantity of disclosures.
Simplification is structural, not symbolic
The Omnibus update created two narratives: dismantling versus refinement. But framing the change in binary terms obscures its structural impacts.
Yes, the volume has been reduced, and the scope has narrowed. At the same time, proportionality has been formalized. An explicit materiality filter has been embedded, and alignment with decision-useful reporting principles has been strengthened.
The more relevant question for practitioners is not whether the framework was weakened or preserved, but where its center of gravity has moved. The revised ESRS centers on calibrated judgment and internal consistency, reshaping sustainability reporting.
What comes next
Confusion now centers on double materiality. If filtering is more explicit and proportionality is embedded, what does a robust assessment look like? Is it still necessary to identify and score every impact, risk and opportunity?
In the next article, we will move decisively from structural interpretation to practical execution. We’ll explain how future guidance will focus on making robust material assessments under the new framework.
