What is VSME, the voluntary sustainability reporting standard for SMEs

The term VSME will be encountered in 2026 by every SME owner selling to large industrial customers or retail chains. This article briefly explains what VSME is, who published it, and when an SME needs to use it.

VSME in brief: a one-sentence definition

VSME (Voluntary Sustainability Reporting Standard for SMEs) is a voluntary sustainability reporting standard for SMEs published by EFRAG. EFRAG submitted the standard to the Commission in December 2024, and the European Commission issued an official recommendation on the matter in July 2025. The final content as a delegated act is being finalised as part of the Omnibus I package; the content may still be refined slightly, but the foundation is already in widespread use.

The goal is singular: to give SMEs a single standard-based way to respond to sustainability data requests from large customers, financiers, and other stakeholders. Without VSME, every SME supplier would have to respond to dozens of different questionnaires that overlap in content but differ in format.

VSME has been specifically designed with the capacity of SMEs in mind. The standard can be used even by a company that has no dedicated sustainability officer or extensive information systems.

Why VSME exists: protecting SMEs from CSRD value chain requirements

When CSRD came into force, it quickly became clear that the sustainability reporting of large companies would transfer an enormous data-request burden onto the supply chain. SMEs began receiving dozens of different ESG forms, each asking for slightly different information in slightly different formats.

EFRAG developed VSME in response to this problem. The standard does two things at once. First, it gives SMEs a ready-made structure for reporting sustainability data, so that information does not need to be compiled from scratch for every enquiry. Second, and more importantly, Omnibus I Directive (EU) 2026/470 introduces the value chain cap principle: CSRD-obligated customers may not request more information from a supplier with fewer than 1,000 employees than is defined by the standard accepted under the final delegated act, and VSME forms the concrete content of that cap.

VSME is therefore both a reporting tool and a practical protection for SMEs against excessive data-request burdens.

The background to the standard’s development is clearly the result of pressure from SME representatives. EFRAG’s original plan would have stretched the full ESRS framework to cover the SME sector as well, which would have meant a heavy reporting burden in practice with no corresponding benefit. VSME is a compromise: a standardised structure that gives the entire value chain a common language, but kept manageable for SMEs.

Who VSME is intended for: three typical situations

VSME is intended for all SMEs, but in practice three situations recur.

1. Value chain supplier. Your company sells to a large CSRD-obligated customer (e.g. Stora Enso, KONE, Wärtsilä, a major retail chain, or a municipality). The customer requests sustainability data as part of its own CSRD reporting. A VSME report is the standardised response to this.

2. A company seeking financing. A bank or investor requests sustainability data before making a financing decision. An increasing number of Finnish banks have added VSME-based questions to their corporate financing processes as part of their own CSRD obligations or SBTi targets.

3. A builder, a company that wants to construct sustainability reporting correctly from the outset. For some SMEs, VSME is simply a good starting point for sustainability reporting, even without external pressure. The standard forces the basics to be done in the right order.

This group often includes growth companies approaching the Omnibus I CSRD threshold (1,000 employees, €450M), family businesses nearing a generational transition, or companies planning a stock market listing. In all of these cases, the foundational VSME work significantly reduces the later workload when heavier obligations arise.

What a VSME report contains, in brief

A VSME report is built around two modules: Basic and Comprehensive. Comprehensive always includes Basic.

Basic Module covers the organisation description, basic employee data, energy use, Scope 1 and Scope 2 emissions, waste, water, and key governance information. It is sufficient for most SME supplier data requests.

Comprehensive Module adds deeper themes: climate risks and transition plan, human rights, diversity, and strategic sustainability targets. It is needed when a customer requires data for its own CSRD report.

A more detailed comparison is available in the article VSME Basic vs Comprehensive: which module fits.

Practical scale matters: the Basic report consists of approximately 30 data points and a few qualitative sections. Comprehensive more than doubles that number and adds several strategic sections. The CSRD ESRS standard set contains over 1,000 data points. That ratio illustrates how much lighter VSME is by design.

Is VSME mandatory, and why it may still be unavoidable

By law, VSME is not mandatory for any SME. The standard has not been written into the CSRD Directive as a mandatory requirement.

In practice, VSME becomes mandatory in two ways. First, if a large CSRD-obligated customer requests sustainability data, there are often only two options: respond with a VSME report or lose the customer relationship. Second, banks and other financiers have started requiring VSME baseline data in financing decisions.

The situation in 2026 is effectively that every SME with significant customers in the industrial, energy, construction, or retail sectors will benefit from building VSME readiness proactively.

In practice, pressure will grow during the second half of 2026, as CSRD-obligated customers prepare their first Omnibus I-era reports for the 2027 financial year. An SME that begins VSME work only when the deadline is imminent will be in a difficult position, because a realistic delivery time is 4–8 weeks and a rushed timeline increases costs.

How VSME differs from GRI and other voluntary frameworks

VSME is not the first voluntary sustainability reporting standard, but it is the first directly linked to EU legislation.

GRI (Global Reporting Initiative) is the oldest and most widely used reporting framework in the world. It was built for large companies and contains hundreds of indicators. GRI and VSME overlap partially: the same data can often be reported under both standards. However, GRI is not recognised as a value chain cap under EU law, so a customer cannot require a GRI report to be accepted in place of VSME.

EcoVadis is an assessment system, not a reporting standard. In an EcoVadis assessment, a third party scores a company’s sustainability performance across four areas. VSME report data supports an EcoVadis assessment but does not replace it.

B Corp is a certification of a company’s overall social responsibility, not a sustainability reporting standard. VSME and B Corp work perfectly alongside each other, but address different questions.

The practical difference is clear: VSME is an SME standard linked to legislation; the others are voluntary frameworks or certifications. An SME that wants to respond to data requests from CSRD-obligated customers needs a VSME report. Other frameworks complement it, they do not replace it.

Frequently asked questions

What does the VSME abbreviation stand for?

VSME stands for “Voluntary Sustainability Reporting Standard for SMEs.”

Who published the VSME standard?

EFRAG (European Financial Reporting Advisory Group) submitted the VSME standard to the Commission in December 2024. The European Commission issued an official recommendation on the matter in July 2025. The final content will be formalised as a delegated act as part of the Omnibus I package.

Is VSME EU law?

VSME itself is not independent legislation and does not oblige SMEs to report. However, the Omnibus I Directive introduces the value chain cap principle: CSRD-obligated companies may not request more from an SME supplier with fewer than 1,000 employees than is defined in the final delegated act (which is based on VSME).

Can a VSME report be done in-house?

Yes. The standard is public and anyone can build a report based on it. In practice, most SMEs lack a ready-made emissions calculation and data foundation, in which case using an external consultant is faster and more cost-effective.

Does VSME differ from other SME standards?

VSME is the only EU-official standard published by EFRAG. There are other SME-level frameworks on the market (e.g. EcoVadis, B Corp), but only VSME is recognised as the value chain cap under EU legislation.

Do you need a VSME report for a customer or bank?

We produce VSME reports from start to finish in 4–8 weeks. You do not need to learn the standard yourself.
