Latest: Revised ESRS now final

In July 2026, the European Commission (EC) adopted the revised European Sustainability Reporting Standards (ESRS). The revised ESRS are largely aligned with the text that the EC consulted on earlier this year based on technical advice prepared by the European Financial Reporting Advisory Group (EFRAG). After a period of uncertainty, change and recalibration, the EC’s adoption of the revised standards gives companies clarity on the reporting requirements. Read our article for more details.

Also in July 2026, the EC adopted the Voluntary Standard for smaller companies. Scroll down to Other developments to find more details.

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 activity and a presence in the EU. In-scope companies are required to prepare sustainability reporting in accordance with the ESRS. The Accounting Directive and CSRD have been further amended by the Stop-the-clock Directive (2025/794) and Content Directive (2026/470). A ‘Quick fix’ Delegated Act (2025/1416) introduced as part of the Omnibus package also impacts CSRD reporting requirements.

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 further amended by the Stop-the-clock Directive (2025/794) and Content Directive (2026/470), introduced as part of the Omnibus package.

Our Hot Topics, tailored to US companies, provide information on the relevant scoping and reporting requirements, as amended by 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.

The first Omnibus package of proposals was introduced in February 2025 to simplify and streamline certain EU legislation (including the CSRD and the CSDDD). While the amendments to the CSRD and the CSDDD have been enacted by the EU, there are other simplification measures which are being introduced in waves, with different parts progressing at varying speeds.

To help you stay informed, we’ve created five separate timelines – each tracking a specific piece of the Omnibus package. This approach will give you a clearer view of the distinct regulatory pieces and their unique path forward. Click each of the boxes below to view a timeline of what’s happened so far and what’s expected next.

While these timelines focus on Omnibus-related developments, the Other developments section below covers other EU sustainability reporting and assurance developments that are ongoing outside the Omnibus process.

As legislative discussions evolve, future dates may shift, so check back regularly for the latest updates.

CSRD, as originally adopted: Transposition

The CSRD, as originally adopted, entered into force in January 2023. Despite the deadline of July 6, 2024 to transpose it into national law, a handful of Member States have not yet transposed.

For Wave 1 companies, these delayed transpositions continue to cause legal uncertainties relating to, for example, continued application of the sustainability reporting regime under the Non-Financial Reporting Directive (NFRD).

CSRD: ESRS for Third-Country Undertakings

Non-EU groups in scope of the CSRD are required to report in accordance with the forthcoming ESRS for Third-Country Undertakings (ESRS-TC). The EC’s adoption deadline for the ESRS-TC is June 30, 2026. However, a de-prioritization process proposed by the EC would further delay this timeline until at least October 2027, leaving little time for non-EU groups to prepare for reporting in FY2029 (based on FY2028 data). EFRAG aims to conduct a 100-day public consultation beginning in July 2026 to deliver technical advice to the EC in January 2027.

CSRD: Guidance

EFRAG has launched an ESRS Knowledge Hub, a new digital gateway designed to help companies and stakeholders navigate the ESRS, support consistent implementation and enhance the transparency and usability of ESRS. The platform includes key ESRS-related materials, including standards, implementation guidance and supporting documents.

CSRD: Voluntary Standards for smaller companies

In July 2026, the EC adopted a voluntary standard for smaller companies that are protected by the value chain cap. Companies in scope of the CSRD would be required to limit information requests to the companies in their value chain with less than an average of 1,000 employees to the disclosures specified in the voluntary standard. The standards are now subject to scrutiny by the European Parliament and the Council before entering into force.

CSRD: Assurance

The CSRD requires the EC to adopt limited assurance standards by July 1, 2027. The EU intends to use the International Standard on Sustainability Assurance (ISSA) 5000, General Requirements for Sustainability Assurance Engagements, as the foundational base for developing these standards. The technical advice associated with these standards is expected to be provided to the EC by September 30, 2026.

CSDDD: Transposition

Member States have until July 26, 2028 to transpose the CSDDD into their respective national law. To avoid a fragmented regulatory landscape, a harmonization principle prohibits Member States from introducing provisions diverging from many of the due diligence obligations within the CSDDD.

CSDDD: Guidance

By March 31, 2029, the EC will establish the CSDDD report content and criteria, which are expected to align with similar reporting criteria in the CSRD.

The EC will issue guidelines to support companies in fulfilling due diligence obligations by July 26, 2027.

CSDDD: Assessments

By July 26, 2031, the EC will assess the effectiveness of certain implementation matters, including whether a scoping approach specific to high-risk sectors should be introduced and whether the value chain definition should be revised.

EU Taxonomy: Amendments

By the end of July 2026 the EC is expected to adopt amendments to the EU Taxonomy’s Climate and Environmental Delegated Acts to revise activity descriptions and technical screening criteria. These proposed revisions aim to better align with other EU legislation and are expected to enter into force by January 1, 2027 and apply from 2026 reporting periods.
