Navigating the EU Omnibus Simplification Package: CSRD


The EU Omnibus Package aims to simplify CSRD by reducing compliance burdens and promoting competitiveness among businesses. 

This article was updated in March 2026 based on the latest developments.


In brief

  • The CSRD aims to enhance transparency and accountability in corporate sustainability reporting, ensuring that companies disclose their ESG impacts.
  • Proposed changes include postponed reporting deadlines, revised thresholds and reduced reporting requirements.
  • The directive encourages businesses to integrate sustainability into their operations and respond effectively to stakeholder expectations.

Recap of the legislation

The Corporate Sustainability Reporting Directive (CSRD) is a pivotal element of the European Green Deal, designed to enhance corporate responsibility and facilitate the transition to a sustainable and inclusive economy. Adopted in 2022, the CSRD significantly expanded previous sustainability reporting requirements by broadening the range of companies obligated to disclose sustainability information. It also introduced the European Sustainability Reporting Standards (ESRS) which emphasize a double materiality approach. This approach requires companies to report not only on how sustainability issues impact their business but also on the effects of their operations on people and the environment, underpinned by quantitative data. The CSRD took effect in January 2024 for large European public-interest companies, with phased implementation for private companies and non-EU parent companies, including Swiss multinationals.

Changes from the EU Omnibus Simplification Package

The release of the first EU Omnibus Simplification Package (“Omnibus Proposal” or “Proposal”) on 26 February 2025 aimed to streamline and simplify sustainability reporting requirements as just recently introduced by CSRD.

The Proposal is using a staggered approach.

  • The first step involved a “Stop-the-Clock” measure to postpone the effective dates of requirements under CSRD. Refer to this EY article for more information. 
  • In the second step, the European Commission amended the CSRD more substantively with a separate directive. This directive primarily focuses on simplification, aiming to reduce both the disclosures required and the number of companies subject to mandatory reporting obligations. 
    • On 16 December 2025, the European Parliament and Council have formally approved the provisional political agreement that was reached on 9 December 2025 on the changes to the CSRD and to the Corporate Sustainability Due Diligence Directive (CS3D) under the Omnibus I package. 
    • The approved text is available here.
    • On the 24th of February 2026 the Council of the EU gave its green light to the ‘Content’ Directive, approved by the European Parliament on 16th December 2025, and the Directive (EU) 2026/470 (‘Content’ Directive) was published in the Official Journal of the EU on the 26th of February, which means its entry into force is set to be the 18th of March 2026 (on the twentieth day after this publication).
    • Member States will have 12 months after the entry into force of the Directive to transpose its provisions into national legislation, except for amendments to the CSDDD, which have to be transposed by 26 July 2028 at the latest. 
  • On 3 December 2025, EFRAG submitted its technical advice to the EU Commission on the draft simplified ESRS (twelve ESRS standards revised and the amended glossary).
  • The Commission will now prepare the Delegated Act revising the first set of ESRS based on EFRAG’s technical advice. Final publication by the Commission is expected by mid-2026.
  • EFRAG also released a Basis for Conclusions and four additional documents to help stakeholders understand the draft simplified ESRS; you can find these and the draft simplified ESRS Standards here.

The rest of the article focuses on the Directive making substantive amendments to CSRD as well as the changes to the ESRS proposed by EFRAG.

ESRS revision: EFRAG Technical Advice-timeline

Key amendments made to CSRD

The debate was very active for several months between the various committees and working groups inside the EU and the following key amendments have been pre-agreed on:

Comparison of the in-scope companies between the original CSRD Directive and the final Omnibus Agreement reached on 16 December 2025.

What happens next?

The amendments to the CSRD are expected to be published in the Official Journal of the EU and entered into force in the first half of 2026. They will then be subject to EU Member State transposition.

Key amendments made to the ESRS

The ESRS have undergone revisions aimed at reducing and modifying datapoints, clarifying provisions and enhancing consistency with other legislation. Public input was gathered in April as part of the consultation process and EFRAG published a Progress Report on 20 June 2025 detailing the work completed on the project so far. The ESRS Exposure Drafts have been published by the end of July 2025 for additional public feedback and review and finalized in October 2025.

On 3 December 2025, EFRAG submitted its Technical Advice to the European Commission. It encompasses:

  • Letter to the Commissioner
  • Twelve revised ESRS standards
  • Revised Glossary
  • Factsheets

By the end of December 2025, EFRAG published its conclusion, including:

  • Basis for conclusion
  • Comparison documents
  • Cost-benefit analysis
  • Explanatory notes relating to CSRD

The workplan for 2026 is still under discussion but will likely include:

  • Update of IG 3 Excel list of datapoints
  • Non-mandatory guidance based on non-mandatory content removed from ESRS
  • Review of existing Q&A and Implementation Guidance 1 and 2
  • New guidance (anticipated financial effects, transition plan)

Below we have listed some key aspects of the revised ESRS:

What happens next?

The EC will now consider EFRAG’s advice when adopting the delegated act that amends the ESRS. The EC may adopt simplified ESRS that differ from the technical advice.

The EC aims to adopt the necessary delegated act as soon as possible, and at the latest six months after the Content Proposal is entered into force. This timeline has been set to allow the ESRS to be adopted as a delegated act in time for entities to apply the revised standards for financial year 2027, potentially with an option for voluntary application for financial year 2026. Until the delegated act is effective, Wave 1 entities are required to continue applying ESRS Set 1.
 

What should companies do now?

In the aftermath of Omnibus I, regulatory shifts have created both opportunities and uncertainties. The extension of timelines offers companies a chance to better prepare, align with new regulations and refine their sustainability practices. To assist companies in navigating next steps, we have outlined some “no-regret” and pragmatic actions to consider, drawing from our client discussions and broader market insights.

 

Monitor

Maintain

  • Strengthen governance and oversight: Use the additional time to enhance sustainability reporting operating models and oversight structures.
  • Ensure readiness: Complete / re-evaluate the double materiality assessment which serves as the foundation of sustainability strategy and disclosures to refine what is deemed truly material.

Prioritize

  • Focus on value-added activities: For example, focus on corporate and sustainability strategies and initiatives as well as on other investor and stakeholder requests.
  • Enhance data infrastructure and assurance readiness: Formalize processes, systems and controls to ensure high-quality data and readiness to undergo assurance.
