The CSRD Omnibus update (Omnibus I) update and EFRAG’s ESRS simplification are reshaping sustainability reporting in Europe and beyond. While regulatory requirements have been streamlined, CSRD disclosure obligations remain firmly in place. This article explains what has changed, what remains unchanged (including double materiality), and how companies can turn simplification into a strategic advantage.
The CSRD Omnibus update (Omnibus I), formally adopted in early 2026, is one of the most significant adjustments to EU sustainability reporting since the Corporate Sustainability Reporting Directive (CSRD) entered into force. Together with EFRAG’s simplified ESRS, the reform reduces administrative burden, tightens CSRD scope thresholds, and removes selected reporting requirements.
But ESRS simplification does not mean CSRD deregulation. Double materiality remains mandatory, disclosure requirements persist, governance expectations continue, and capital markets still demand decision-useful sustainability data.
For sustainability managers, compliance officers, procurement leaders, and reporting specialists worldwide, the question is no longer whether to prepare for CSRD — but how to implement CSRD reporting efficiently and strategically under the revised framework.
The CSRD Omnibus update was introduced to address growing concerns around regulatory complexity and European competitiveness. Policymakers aimed to reduce administrative burden while maintaining the directive’s core objective: transparent, comparable sustainability reporting that supports decision-making by investors and other stakeholders.
Key elements of the Omnibus I reform include:
The overarching message is clear: reduce complexity, maintain transparency, and improve proportionality.
In March 2025, the European Commission formally requested EFRAG to deliver technical recommendations for simplifying the ESRS framework. By late 2025, EFRAG submitted its draft simplified standards.
The result is a significant structural streamlining.
In numerical terms, the original ESRS Set 1 contained roughly 1,000 data points across cross-cutting and topical standards. The simplified ESRS substantially reduce mandatory disclosures, focusing only on material information.
The objective is to shift sustainability reporting away from mechanical compliance toward decision-useful, relevant information.
Despite substantial streamlining, the simplified ESRS preserve the foundational CSRD architecture. The key change is how companies report, not what they are accountable for.
Double materiality under CSRD remains mandatory. Companies must continue conducting a double materiality assessment (DMA) covering:
This remains the methodological backbone of CSRD reporting and the trigger for what becomes material under ESRS.
Companies must report on:
Simplification reduces volume — not accountability.
While the preference for direct value chain data has been relaxed, companies must still assess material impacts across their activity chain where relevant.
Limited assurance remains mandatory. Digital tagging (XBRL) preparation is still required.
In short: ESRS simplification changes the "how," not the "why."
One of the biggest misconceptions surrounding the CSRD Omnibus update is the assumption that companies can now pause preparations. That would be a strategic mistake.
Sustainability data remains capital-market relevant. Banks, investors, insurers, and rating agencies continue integrating ESG metrics into risk modeling and financing decisions. Even companies temporarily falling outside scope may face indirect pressure through:
Board oversight, internal controls, and structured ESG data management remain essential to produce audit-ready disclosures and to connect reporting with risk management.
The inclusion of a review clause means scope expansion cannot be ruled out. Companies that dismantle preparation efforts may later face higher implementation costs.
In practice, simplification creates an opportunity to:
Companies that use this window strategically can transform compliance into structural advantage.
Rather than treating the Omnibus update as regulatory relief alone, forward-looking organizations view it as a recalibration moment.
For companies preparing for CSRD Wave 2, the period ahead of the 2028 publication window is critical. The revised timeline should be used to validate materiality, test data flows, and establish audit-ready governance — not to delay implementation.
A pragmatic CSRD Wave 2 roadmap includes:
The extended timeline should be used to optimize processes — not delay them.
Efficient CSRD implementation under simplified ESRS still requires a structured methodology, reliable data integration, and controls that support limited assurance. IntegrityNext enables companies to build audit-ready processes while reducing manual workload.
The IntegrityNext solution follows a five-step process aligned with EFRAG guidance:
Key capabilities include:
Automation, year-over-year logic, and intelligent scope management reduce manual workload while improving audit readiness. The result is not just regulatory compliance — but structured, scalable sustainability governance.

The CSRD Omnibus update (Omnibus I) update and ESRS simplification significantly reduce reporting complexity. Yet the directive’s structural foundations remain firmly intact.
For companies that approach the reform strategically, simplification offers a rare opportunity: to build leaner, smarter, and more integrated sustainability reporting systems. Those who pause risk future inefficiency. Those who prepare gain resilience and competitive positioning.
The CSRD Omnibus update (Omnibus I) is a 2026 reform package that narrows scope thresholds, postpones reporting timelines, and simplifies ESRS disclosure requirements while maintaining core sustainability reporting principles.
Wave 2 companies must report for financial year 2027, with their first CSRD report published in 2028.
The simplified ESRS reduce mandatory data points by approximately 60%, depending on materiality.
Yes. Double materiality remains mandatory and forms the methodological foundation of CSRD reporting.
No. Under the Omnibus reform, sector-specific ESRS standards have been discontinued.
The simplified ESRS improve interoperability with ISSB, particularly regarding greenhouse gas boundaries and financial impact disclosures.
No. Although timelines have shifted, governance, audit readiness, and stakeholder expectations make continued preparation advisable.

Scope 3 emissions often account for the vast majority of a company’s carbon footprint. Yet building a scalable Scope 3 supplier engagement strategy across thousands of suppliers remains one of the most complex challenges in supply chain decarbonization. Drawing on insights from IntegrityNext’s Scope 3 webinar series, this article explores how companies can move from one-off data requests to meaningful, scalable supplier collaboration.

CSDDD requirements are raising the bar on responsible sourcing. It’s no longer enough to publish a supplier code of conduct, you must prove how you identify, prioritize, and address human rights and environmental risks across your supply chain. This article explains the core CSDDD requirements and how to operationalize them at scale.
