In May, we looked at the European Commission’s proposed simplifications to the European Sustainability Reporting Standards (ESRS) and the Sustainable Finance Disclosure Regulation (SFDR). On 3rd July 2026, those proposals took a significant step forward, with the Commission formally adopting the revised ESRS alongside a new voluntary sustainability reporting standard for smaller companies.
While the revised standards are still subject to scrutiny by the European Parliament and Council, investment teams now have a much clearer picture of the reporting framework they’ll be working with from 2027 onwards. Here’s what has changed, and what it means for investors and stewardship teams.
The Commission’s adoption package confirms several important changes that build on the direction of travel set out under Omnibus I.
The revised ESRS have now been adopted via delegated act. They will enter into force following scrutiny by the European Parliament and Council (a two-month period, potentially extendable by a further two months). The standards are expected to apply to financial years beginning on or after 1 January 2027, with voluntary early adoption available for 2026.
A voluntary standard for smaller companies. Alongside the revised ESRS, the Commission introduced a standalone voluntary sustainability reporting standard for companies outside the scope of the Corporate Sustainability Reporting Directive (CSRD). This creates a common reporting baseline for SMEs and other unlisted businesses, helping to improve consistency without bringing them into mandatory reporting requirements.
A new value-chain cap. One of the most practical changes for investors is the introduction of a value-chain cap. Companies reporting under CSRD will no longer be able to request more sustainability information from value-chain partners than is required under the new voluntary standard. For investment teams engaging with SMEs, private companies and other non-CSRD entities, this sets clearer expectations around what information can reasonably be requested.
Significant simplification. The Commission also confirmed the scale of the simplification:
Our previous article explored the proposed direction of travel; these figures now represent the final calibration of the revised standards.
For analysts, stewardship professionals and engagement teams, three implications stand out.
1. Data requests will become more targeted
With fewer mandatory disclosures and a formal value-chain cap, engagement requests to portfolio companies (particularly SMEs and private holdings) will need to evolve. Continuing to request extensive, pre-Omnibus datasets is likely to create unnecessary friction and lower response rates. Instead, the emphasis shifts towards materiality and judgement. Which information genuinely supports your investment thesis? Which disclosures provide the clearest evidence of risk, opportunity and progress?
2. Engagement evidence needs to reflect the revised standards
As reporting frameworks evolve, stewardship records will increasingly be assessed against the revised ESRS rather than earlier drafts.
That means ensuring engagement activity:
3. Teams can now plan against confirmed timelines
The adoption also provides greater certainty. Rather than preparing for proposals, investment teams can begin planning engagement programmes, reporting cycles and data collection around a defined implementation timetable, including the scrutiny period, entry into force and expected application from FY2027.
As reporting expectations become more focused, so too must engagement processes. SI Engage helps investment and stewardship teams operationalise the revised ESRS by enabling them to:
The July 2026 adoption marks an important milestone; the conversation has moved beyond proposed simplifications and towards implementation. For investment teams, the priorities are now clear:
We’ll continue to follow developments as the scrutiny period progresses and organisations begin preparing for early adoption.
