October 31 marked the end of the consultation period on the exposure draft for the new European Sustainability Reporting Standards for Certain Non-EU Undertakings in Accordance with Article 40a of the Accounting Directive (ESRS-40a). The exposure draft was developed by EFRAG (the EU’s advisory group on corporate reporting) for group level sustainability reporting when an ultimate non-EU parent meets the non-EU parent scoping. EFRAG is expected to deliver its technical advice to the European Commission (EC) in January 2027 based on the feedback of this consultation. Read our article for more details.

In September, the revised European Sustainability Reporting Standards (ESRS) and the Voluntary Standard for smaller companies (VS) were published in the Official Journal of the EU. Read our article for more details.

Also in September, the Committee of European Auditing Oversight Bodies (CEAOB) delivered technical advice to the EC on an EU sustainability limited assurance standard based on International Standard on Sustainability Assurance (ISSA) 5000, including proposed EU-specific modifications. The EC is required to adopt the standard by delegated act by July 1, 2027.

CSRD

The CSRD amended the Accounting Directive (2013/34/EU) and applies to EU companies that meet certain employee and turnover (revenue) thresholds, and to non-EU groups with substantial operations in the EU. In-scope companies are required to prepare sustainability reporting in accordance with the ESRS and non-EU group level sustainability reporting is prepared according to the standards adopted under Article 40a when an ultimate non-EU parent meets the non-EU parent scoping. As part of the Omnibus package, the Accounting Directive and CSRD have been amended by the Stop-the-clock Directive (2025/794) and Content Directive (2026/470). A ‘Quick fix’ Delegated Act (2025/1416) also impacts CSRD reporting requirements. Read more about the Omnibus package in our Hot Topic.

CSDDD

The CSDDD (2024/1760) applies to companies worldwide that meet certain employee, revenue and/or royalty thresholds. In-scope companies are required to comply with certain due diligence and reporting obligations related to actual and potential adverse human rights and environmental impacts. The CSDDD has been amended by the Stop-the-clock Directive (2025/794) and Content Directive (2026/470), both introduced as part of the Omnibus package.

Global implications of the Corporate Sustainability Reporting Directive

Omnibus amendments have significantly reduced the scope of the CSRD and its applicability beyond the EU.

Global implications of the Corporate Sustainability Due Diligence Directive

Omnibus amendments have significantly reduced the scope and streamlined due diligence obligations to ease burden on companies.

While the amendments to the CSRD and the CSDDD have been enacted by the EU, there are other simplification measures that are being introduced in waves, with different parts progressing at varying speeds.
