- In 2026, VSME remains 100% voluntary: no regulatory obligation or threshold requires SMEs to adopt it.
- It is mainly adopted by non-listed SMEs requested by buyers subject to CSRD, or wanting to structure their ESG approach.
- The Basic module is built around roughly 60 indicators, compared to over 600 in the full ESRS framework.
- No certification or external audit is required: companies freely choose their reference year and publication format.
What is VSME and why does it matter for SMEs?
The VSME (Voluntary Sustainability Reporting Standard for SMEs) is a voluntary reporting framework developed by EFRAG to help non-listed SMEs structure and communicate their ESG practices. It offers a proportionate approach scaled to their resources, built around 56 simplified indicators covering environment, social and governance topics.
Its purposes are multiple: strengthening credibility with investors, responding effectively to CSR requests from clients subject to CSRD, building a realistic internal roadmap and improving business transparency.
Is VSME mandatory or voluntary in 2026?
In 2026, VSME remains 100% voluntary. No regulatory obligation requires SMEs to use it, and there are no specific thresholds for adoption.
Companies freely choose their reference year, publication format and reporting frequency. No certification or external audit is required.
This flexibility explains its growing success among SMEs that want to structure their ESG approach while keeping the administrative burden manageable.
Double materiality, while not mandatory, is strongly recommended to give meaning to action priorities.

Which companies are concerned by VSME in 2026?
In 2026, no company is legally required to apply VSME. However, several categories are directly or indirectly encouraged to use it.
Non-listed SMEs and mid-sized companies
VSME allows them to formalise a solid ESG strategy without the constraints of CSRD reporting. It is a lever for internal professionalisation and structuring.
Suppliers and subcontractors of large groups
Companies subject to CSRD must collect ESG data throughout their value chain. VSME gives suppliers a standardised format to respond effectively to these requests.
Growing companies and startups
Early adoption of VSME is a preparation tool for future obligations, building a reliable and usable ESG data foundation from the outset.
Exporting SMEs and subsidiaries
The European VSME framework makes ESG communication easier across multiple jurisdictions. It helps boost credibility with international partners and financiers.
VSME, CSRD and ESRS: what are the differences?
VSME builds on the work of EFRAG — also behind the ESRS — but is designed exclusively for SMEs not subject to CSRD. It covers the same themes, in a simplified and voluntary format. Our article on the differences between VSME and CSRD covers the use cases for each type of SME in detail.
| Criterion | CSRD / ESRS | VSME |
|---|---|---|
| Nature | Mandatory directive | Voluntary framework |
| Scope | Large companies, listed mid-sized companies | Non-listed SMEs |
| Number of indicators | Around 600 | Around 56 |
| External audit | Mandatory | Not required |
| Double materiality | Mandatory | Recommended |
CSRD imposes a formal, audited framework, while VSME leaves room for proportionality and a learning-by-doing approach. Adopting it in 2026 means getting ahead of the sustainability curve without overloading your teams.
