EU Adopts Revised Sustainability Reporting Standards: What Companies Need to Know in 2026
On 3 July 2026, the European Commission adopted revised European Sustainability Reporting Standards (ESRS), introducing major simplifications and a voluntary standard for smaller businesses, reshaping how organizations across the EU report on sustainability.
Checked: 17 October 2026
Significant developments in EU sustainability reporting landed on 3 July 2026: the European Commission formally adopted a reworked set of sustainability reporting standards—the ESRS—and, for the first time, established a voluntary reporting framework tailored to smaller companies who otherwise fall outside the scope of the Corporate Sustainability Reporting Directive (CSRD). These changes aim to ease reporting burdens, lower associated costs, and guide both large and smaller undertakings on the next phase of sustainability disclosure in the Union.
Immediate Impact: What Changed?
The revised ESRS dramatically reduce the number of mandatory data points (by over 60%) and total data points (by more than 70%) compared to the previous standards. This is expected to lower the average sustainability reporting cost per company by more than 30%. For the first time, there is also a dedicated voluntary reporting standard for smaller undertakings—companies not captured by CSRD but increasingly engaged in value chains where sustainability disclosures are requested.
Legal and Regulatory Status
Both the revised ESRS and the voluntary standard were adopted by the Commission—formally on 3 July 2026—and sent to the European Parliament and Council for scrutiny. They are expected to enter into force after the mandated scrutiny period lapses (two months, extendable by another two months if necessary). Two related delegated acts were also adopted: one simplifies existing requirements under Delegated Regulation (EU) 2023/2772, while the other provides the legal basis for voluntary standards for value-chain-capped undertakings. These will only take effect after their publication in the EU Official Journal.
What Should Companies Do Now?
Companies covered by the CSRD should track the scrutiny and implementation process, anticipate eventual compliance with the simplified standards, and begin preparing to use the streamlined data points. Smaller firms—those outside CSRD but subject to value chain disclosure demands—can review the voluntary standard for possible adoption. Both groups should monitor official guidance and any clarifications from the Platform on Sustainable Finance, which has emphasized early adoption opportunities and the need for stable, user-friendly documentation.
Transitional Guidance and Expected Benefits
According to expert responses, transitional guidance will be essential, especially during the phased introduction of these standards. The Commission’s simplifications aim to ensure reporting remains both high-quality and proportional to company size and capacity—vital for reducing burdens and increasing the usability of sustainability data in Europe’s wider regulatory and financial ecosystem.
Looking Ahead: Stability and Moving Forward
After these new frameworks enter into force, stakeholders expect the Commission will maintain the revised ESRS and voluntary standards with relative stability, giving companies and value-chain actors a predictable environment in which to adapt. Monitoring the EU regulatory pages will be crucial for timely information on entry into force, further clarifications, or additional guidance.
Key takeaways
- The revised ESRS, adopted in July 2026, significantly reduce the number of required data points for companies reporting under CSRD.
- A voluntary sustainability reporting standard now exists for smaller companies not under CSRD scope, aiding their value chain integration.
- Both the main and voluntary standards await conclusion of a scrutiny period and publication in the Official Journal before they apply.
- Companies should monitor the adoption process and begin preparing for the simplified requirements; early adopters may benefit from guidance issued by authorities.
- The overall aim is to maintain high-quality reporting while greatly reducing the burden for firms across the EU.
