VSME explained: the voluntary sustainability reporting standard for SMEs
VSME explained: what the voluntary sustainability reporting standard for SMEs covers, how its modules work, and why customer and finance data requests matter.
The Voluntary Sustainability Reporting Standard for non-listed small and medium-sized enterprises (VSME) is designed to help smaller companies answer sustainability data requests without building a full corporate reporting machine. The important point is simple: voluntary does not mean irrelevant when large customers, banks and investors keep asking for evidence.
Information only
This guide is for general information only. It is not legal, accounting, regulatory, tax, procurement, investment or financial advice. Sustainability reporting rules, European Union policy, lender expectations and customer requests can change. Check current official sources and professional advice before relying on this for compliance, reporting or finance decisions.
The VSME exists because sustainability reporting has a trickle-down problem. The Corporate Sustainability Reporting Directive (CSRD) applies directly to larger companies, but those companies often need data from suppliers, borrowers and portfolio companies, including climate evidence shaped by ESRS E1. That means a small manufacturer, software provider or logistics firm can face repeated environmental, social and governance (ESG) questionnaires even when it is not legally required to publish a CSRD report.
The standard's best use is not as a trophy report. It is a reusable evidence file. A company that answers the same emissions, workforce, policy and governance questions every quarter should not have to rebuild the answer from scratch each time. VSME gives that company a common structure.
Core test
VSME is useful when it turns repeated sustainability requests into a controlled data process. It is much less useful if it becomes a glossy report with no evidence behind it.
Quick answer
| Question | Short answer |
|---|---|
| What is VSME? | A voluntary sustainability reporting standard developed by the European Financial Reporting Advisory Group (EFRAG) for non-listed micro, small and medium-sized enterprises. |
| Is it the same as CSRD? | No. CSRD is a legal reporting regime for in-scope companies. VSME is voluntary and has no legal authority on its own. |
| Who is it for? | Companies outside mandatory CSRD scope that still need to answer sustainability information requests from customers, banks, investors or larger business partners. |
| How is it structured? | It has a Basic Module and a Comprehensive Module. The Basic Module is the starting point. The Comprehensive Module adds datapoints more likely to be requested by banks, investors and corporate customers. |
| Why does it matter? | It could become the common language for proportionate sustainability data requests, especially where the European Commission wants larger companies and financial institutions to avoid excessive demands on smaller businesses. |
Data checked
This article was checked on 18 June 2026 against the European Financial Reporting Advisory Group (EFRAG) VSME project page and VSME Standard, the European Commission's SME Relief Package, the Commission's 30 July 2025 VSME recommendation material and EUR-Lex. Reporting scope, Omnibus negotiations and future delegated acts can change.
Why VSME exists
Europe has tried to solve two things at once. It wants better sustainability information from companies, but it also wants to avoid pulling smaller businesses into a full corporate reporting burden. That is the tension behind VSME.
The European Commission's SME Relief Package said Europe had about 24 million small and medium-sized enterprises, representing 99% of EU businesses and around two thirds of private-sector jobs. That scale matters. If every large-company reporting process creates a bespoke questionnaire for every small supplier, the administrative burden spreads far beyond the companies that are directly in scope.
EFRAG describes VSME as a way to help non-listed micro, small and medium-sized enterprises answer sustainability information requests from banks, investors and larger companies. The Commission later encouraged large companies and financial institutions to base their requests on the standard as far as possible. The policy logic is clear: if smaller companies are going to be asked for data anyway, the request should be more standardised and proportionate.
Who VSME is for
VSME is aimed at non-listed companies outside the mandatory CSRD regime. In practical terms, that usually means smaller companies that are not preparing a formal CSRD sustainability statement, but still face sustainability questions in tenders, lending, investment, supplier onboarding or customer renewals.
| Company type | VSME relevance | Common trigger |
|---|---|---|
| Micro enterprise | The Basic Module is intended to be the simplest starting point. | A bank, buyer or public tender asks for basic emissions, workforce or policy information. |
| Small enterprise | VSME can organise repeated ESG and supplier evidence requests. | A larger customer asks for sustainability data for its own value-chain reporting. |
| Medium-sized enterprise | The Comprehensive Module may be useful when customers or lenders want more detail. | Investor diligence, credit assessment, tender scoring or customer reporting calendars. |
| Listed or directly in-scope company | VSME is not a substitute for mandatory reporting requirements. | The company needs to assess CSRD, European Sustainability Reporting Standards (ESRS), local law or other applicable rules. |
The size thresholds behind the standard
EFRAG's VSME Standard uses EU accounting categories for micro, small and medium-sized undertakings. These thresholds are useful for orientation, but a company should not treat them as a substitute for legal scoping advice.
| Category | Balance sheet total | Net turnover | Employees |
|---|---|---|---|
| Micro | Not more than EUR 450,000 | Not more than EUR 900,000 | Not more than 10 |
| Small | Not more than EUR 5 million | Not more than EUR 10 million | Not more than 50 |
| Medium-sized | Not more than EUR 25 million | Not more than EUR 50 million | Not more than 250 |
VSME vs CSRD vs ESRS
The easiest mistake is to treat VSME as "CSRD for small companies". That is too blunt. VSME uses a more proportionate structure and is voluntary. CSRD is the legal reporting regime. The European Sustainability Reporting Standards (ESRS) are the detailed standards used by companies reporting under CSRD.
| Framework | What it is | What it does not do |
|---|---|---|
| VSME | A voluntary standard for non-listed SMEs outside mandatory CSRD scope. | It does not create a legal reporting duty by itself. |
| CSRD | The EU corporate sustainability reporting law for in-scope companies. | It does not make every smaller supplier publish a full CSRD report. |
| ESRS | The detailed European standards used for CSRD reporting. | They are not the same as VSME, although VSME covers similar sustainability topics in a proportionate way. |
Basic Module vs Comprehensive Module
The standard has two modules. The Basic Module is the foundation. The Comprehensive Module builds on it and adds information that banks, investors and corporate clients are more likely to request.
| Module | Best use | Decision test |
|---|---|---|
| Basic Module | Creating a proportionate sustainability evidence base. | Can the company answer common questions on practices, energy, greenhouse gas (GHG) emissions, pollution, water, resource use, workforce, health and safety, remuneration and business conduct? |
| Comprehensive Module | Responding to more detailed requests from banks, investors and larger customers. | Does the requester need extra information on strategy, policies, climate transition, biodiversity, workforce characteristics, human rights or governance incidents? |
What the Basic Module asks for
The Basic Module is still not a one-page pledge. It asks for structured information across environmental, workforce and governance topics. For many smaller companies, the first value of VSME is simply showing which information exists, which owner holds it and where the evidence is weak.
| Basic area | What it means in practice | Evidence to gather |
|---|---|---|
| Basis for preparation | What has been reported, for which period and using which boundary. | Entity list, reporting period, owner, version history and scope notes. |
| Energy and GHG emissions | Energy use and emissions information, with method notes and limitations. | Energy bills, fuel records, emissions factors, calculation workbook and exclusions. |
| Pollution, biodiversity, water and resources | Whether operations create material environmental impacts or resource-use issues. | Permits, site data, waste records, water data, materials data and screening notes. |
| Workforce | Basic information on employees, health and safety, remuneration and training. | Headcount, contract type, incident records, training logs and pay-policy evidence. |
| Business conduct | Whether the company has anti-corruption and anti-bribery controls. | Policy documents, training records, incident logs and governance sign-off. |
What the Comprehensive Module adds
The Comprehensive Module is for companies that need a stronger evidence pack. It is more likely to matter when a large customer, bank, investor or acquirer is not satisfied with basic metrics alone.
| Additional area | Why a requester may ask | Reader judgement |
|---|---|---|
| Strategy and business model | To understand whether sustainability issues affect how the business operates or competes. | This turns reporting from isolated data into business context. |
| Policies, actions and targets | To test whether the company has controls and direction, not only numbers. | Weak targets or policies should be described honestly rather than inflated. |
| Climate transition | To assess whether emissions data connects to credible operational change. | A footprint with no reduction pathway may still be useful, but it is not a transition plan. |
| Human rights and workforce details | To assess social risk in supply chains, operations and workforce practices. | Evidence quality matters more than generic policy language. |
| Governance incidents | To identify bribery, corruption or conduct issues that could affect trust. | Silence is not a control. The company needs a record and escalation process. |
A practical example
Imagine a UK components supplier with 75 employees and several large European customers. The supplier is not directly preparing a CSRD report. But its customers ask for energy data, Scope 1 and 2 emissions, anti-bribery policy evidence, health and safety records, workforce information and supplier controls.
Without a standard, the company answers each questionnaire manually. One customer asks for calendar-year data. Another asks for financial-year data. One asks for emissions in tonnes of carbon dioxide equivalent. Another asks for energy in kilowatt hours. The same information is copied, reformatted and checked repeatedly.
With a VSME-style evidence file, the company can create a controlled baseline: who owns each datapoint, where the source documents sit, what method was used, which exclusions apply and when the information was last updated. That does not remove every questionnaire, but it makes the answers less improvised.
What VSME does not solve
VSME is a reporting standard, not a sustainability strategy. It can organise evidence, but it cannot make weak data strong or make a poor climate claim credible. A company still needs to understand its actual impacts, risks, controls and customer exposure.
- It does not replace legal scoping for CSRD, ESRS (European Sustainability Reporting Standards) or local reporting rules.
- It does not guarantee that every customer, bank or investor will accept the same data format.
- It does not prove that a company is sustainable.
- It does not remove the need for source documents, methodology notes and internal review.
- It does not turn voluntary reporting into a public claim that should be used without care.
What companies should do first
The first step is not to draft a long report. It is to map the recurring questions the company already receives. If customers repeatedly ask for emissions, policies, workforce data and supplier controls, those questions define the first evidence pack.
- Collect recent customer, lender, investor and tender questionnaires.
- Group the repeated questions into VSME-style topics.
- Assign one owner for each datapoint.
- Gather source evidence rather than only final answers.
- Record methods, assumptions, exclusions and reporting period.
- Decide whether the Basic Module is enough or whether the Comprehensive Module is needed.
- Review claims language before using the information externally.
How readers should judge VSME
The useful question is not whether VSME is mandatory. It is whether it reduces noise. A good voluntary standard gives smaller companies a fair way to answer real sustainability questions without copying a large-company reporting regime. A weak implementation just creates another form to fill in.
The market signal is whether banks, investors and large companies actually align their requests around it. If they do, VSME could become a practical bridge between formal reporting rules and the messy reality of supplier evidence. If they do not, smaller companies may still face the same fragmented questionnaire burden under a new name.
Bottom line
VSME matters because the reporting burden is no longer only about who is legally in scope. It is about who gets asked for evidence. The standard is strongest when it helps smaller companies answer those requests once, carefully, and reuse the answer with confidence.
VSME FAQ
Is VSME mandatory?
No. VSME is voluntary. It is designed for non-listed SMEs outside mandatory CSRD scope. That said, voluntary information can still become commercially important if customers, banks or investors ask for it.
Does VSME replace CSRD?
No. CSRD is a legal reporting regime for companies in scope. VSME is a proportionate voluntary standard for smaller companies outside that regime. A company that may be directly in scope should assess CSRD and ESRS separately.
Should every SME use the Comprehensive Module?
No. The Basic Module is the starting point. The Comprehensive Module makes sense when the company receives more detailed requests or needs stronger evidence for finance, investor, tender or customer conversations.
Can VSME help with supplier questionnaires?
Yes, that is one of its strongest practical uses. It can help a company turn repeated requests into a reusable evidence pack with owners, sources, methods and review dates.
Does VSME prove a company is sustainable?
No. It is a reporting and evidence structure. Readers should still look at data quality, methods, policies, targets, controls, actual performance and whether public claims are fair.

What to watch next
The main signals to watch are whether the European Commission adopts a delegated voluntary standard, whether Omnibus negotiations change the value-chain cap or reporting scope, whether EFRAG updates VSME support material, and whether major banks or large-company buyers publish common VSME-based request templates.
