As soon as an SME takes an interest in sustainability reporting, it runs into a jungle of acronyms: CSRD, ESRS, GRI, EcoVadis, ISO 26000, carbon footprint assessment… and now VSME/VS. They all deal with environmental, social and governance matters, but they differ in their target audience, their nature and their legal force. Some are mandatory, others purely voluntary; some are standards, others are certifications or simply guidelines.
This page positions VSME/VS among these frameworks, without overselling it. The aim is not to name a ‘winner’, but to understand what each framework is really for, so that you can make an informed choice. For the definition of the standard itself, its modules and its status, see the pillar page VSME/VS standard: definition, modules and status.
How to read this comparison
Before comparing them, three points need to be borne in mind, because tools of different kinds are often lumped together.
Voluntary or mandatory. Is a framework imposed by law, with penalties for non-compliance, or does the company choose it? The CSRD is a legal obligation for companies within its scope. VSME/VS, on the other hand, is voluntary: applying it entails no penalty and no mandatory filing.
Standard, certification or guide. A standard or norm sets out what must be disclosed (VSME/VS, the ESRS, GRI). A certification or rating involves a third party that assesses the company and awards a score or a label (EcoVadis). Guidelines provide a framework for reflection without imposing a report format or verification (ISO 26000). Confusing these three families leads to misleading comparisons.
The target audience. Who is the tool primarily aimed at? A large listed company, an unlisted SME, a multinational, any type of organisation? VSME/VS was designed specifically for small and medium-sized enterprises, whereas most other frameworks are aimed primarily at large players.
The table below provides an overview; the following sections go through each comparison in detail, before a summary at the end of the page.
VSME/VS vs CSRD and ESRS
Important: the ESRS changed on the same day. On 3 July 2026, the Commission adopted a second delegated act, C(2026) 5010, which simplifies the ESRS themselves. Published in the Official Journal of the EU on 21 September 2026 (Delegated Regulation (EU) 2026/1563), it will enter into force on 10 November 2026 and will apply to financial years beginning on or after 1 January 2027: it reduces the number of mandatory datapoints by 61%. The comparisons below therefore relate to an ESRS framework that has already been simplified – the gap in workload compared with the voluntary standard remains significant, but it is narrowing.
Since then: on 28 August 2026, EFRAG published the list of datapoints for these revised ESRS, open for error reporting until 23 October 2026. It concerns the ESRS, not the voluntary standard — details and scope in our regulatory watch.
This is the most frequently requested comparison, and the most fundamental. The CSRD (Corporate Sustainability Reporting Directive) is the European directive that makes sustainability reporting mandatory for companies within its scope. The ESRS (European Sustainability Reporting Standards) are the technical standards that set out in detail what these companies must disclose under the CSRD. In other words, the CSRD is the legal framework and the ESRS are its content.
Since the so-called ‘Omnibus I’ directive, the scope of the CSRD has been sharply narrowed. It now only covers companies that exceed two cumulative thresholds: more than 1,000 employees and more than €450 million in net turnover. This is an ‘and’ test, not a ‘two out of three criteria’ test: a company that crosses only one of these thresholds remains outside the mandatory scope.
Three fundamental differences separate VSME/VS from the ESRS:
- Legal force. The ESRS are mandatory under the CSRD; VSME/VS is voluntary.
- Comprehensiveness. VSME/VS is deliberately lighter. It is organised around a Basic Module (disclosures B1 to B11) and a Comprehensive Module (disclosures C1 to C9), whereas the ESRS cover a much broader and more detailed range.
- Double materiality. The ESRS are based on this principle – analysing both the company’s impact on its environment and the impact of sustainability matters on the company. VSME/VS does not require this double materiality assessment, which considerably reduces the preparatory work.
A frequently misunderstood point: narrowing the scope of the CSRD does not make the demand for ESG data disappear. It shifts many companies that are no longer subject to the obligation towards voluntary reporting, which is precisely what VSME/VS is designed for. This trend is covered in detail in our news and regulatory watch.
VSME/VS vs GRI
GRI (Global Reporting Initiative) is the long-established international framework for sustainability reporting. Also voluntary, it is widely used around the world, particularly by large organisations, and favours a rich and largely narrative approach: organisations describe their policies, impacts and stakeholders, often in lengthy reports.
By comparison, VSME/VS stands out for its European, SME-focused target audience and its conciseness. Whereas GRI aims for comprehensiveness and an international audience, VSME/VS offers a shorter, standardised baseline, aligned with the European regulatory context and designed for companies that have neither a CSR department nor the time to devote to hundreds of pages. The two are not in opposition: an SME that has already published a GRI report will be able to reuse some of its data for a VSME/VS report, and vice versa.
VSME/VS vs EcoVadis
Here, the comparison changes in nature – and that is precisely the trap. EcoVadis is not a reporting standard, but a third-party rating. The company completes a questionnaire and provides evidence, and EcoVadis awards a score and a medal. The result is an external assessment, comparable from one company to another and widely used in buyer–supplier relationships.
VSME/VS, by contrast, is a reporting framework: the company itself produces and publishes its information, without a third party awarding it a rating. VSME/VS therefore does not ‘replace’ EcoVadis: one rates, the other structures a disclosure. In practice, a well-built VSME/VS report can feed into the response to an EcoVadis questionnaire by providing data that has already been gathered, dated and sourced. Responding to requests from contracting customers is covered in depth in the pillar page VSME/VS and the value chain.
VSME/VS vs ISO 26000
ISO 26000 is an international standard, but of a particular kind: it consists of guidelines on social responsibility. It is not certifiable and does not set a report format. It helps an organisation understand CSR issues and structure its approach around broad principles (governance, human rights, the environment, fair operating practices, etc.).
The difference is therefore clear: ISO 26000 guides an approach, whereas VSME/VS produces a structured report. A company can quite easily draw on ISO 26000 to frame its CSR policy, then use VSME/VS as the format for publishing concrete, comparable information. The two complement rather than oppose each other: one sheds light on the ‘why’ and the ‘how to get started’, the other organises ‘what to disclose’.
VSME/VS vs carbon footprint assessment
A carbon footprint assessment – or, more broadly, the calculation of greenhouse gas emissions – is a targeted exercise: measuring an organisation’s carbon footprint. It is a valuable tool, but it covers only part of the sustainability spectrum.
VSME/VS is broader: climate and energy are just one topic among others. Its Basic Module also covers pollution, biodiversity, water, the circular economy and waste, as well as social matters (workforce, health and safety, training) and governance. The emissions calculation in fact feeds directly into one of the disclosures required by VSME/VS (disclosure B3, ‘energy and GHG emissions’). In other words, a carbon footprint assessment that has already been carried out is a building block of the VSME/VS report, not a substitute for it. The data collection method is explained in detail in the guide Applying the VSME/VS standard in SMEs and micro-enterprises.
Summary table
The table below summarises the main differences against four criteria: the target audience, the scope, the nature of the tool and whether it is voluntary or mandatory.
| Framework | Main target | Scope | Nature | Voluntary / mandatory |
|---|---|---|---|---|
| VSME/VS | Unlisted SMEs / micro-enterprises | Streamlined ESG (Basic B1-B11, Comprehensive C1-C9), without double materiality | Reporting standard | Voluntary |
| CSRD / ESRS | Large companies (> 1,000 employees AND > €450 million net turnover) | Very extensive ESG, double materiality | Directive + standards | Mandatory (within scope) |
| GRI | Organisations, mainly large, internationally | Broad, narrative | Reporting standard | Voluntary |
| EcoVadis | Suppliers assessed by contracting customers | Scored multi-theme questionnaire | Third-party rating | Voluntary (but often requested) |
| ISO 26000 | Any organisation | CSR, broad principles | Guidelines (not certifiable) | Voluntary |
| Carbon footprint assessment | Any organisation | GHG emissions only | Calculation method | Depends on the case |
On a simple scale running from purely voluntary to strictly mandatory, VSME/VS, GRI and ISO 26000 sit on the voluntary side; the CSRD and its ESRS occupy the mandatory end; EcoVadis remains voluntary in law, but is often something companies have to go along with in practice, because customers impose it.
Legal status – as of 8 November 2026. VSME/VS is a standard developed by EFRAG (submitted to the Commission on 17 December 2024) and endorsed by Recommendation (EU) 2025/1710 of 30 July 2025, a non-binding soft law instrument. A voluntary standard, often referred to by the acronym ‘VS’, was also adopted by the Commission through a delegated act on 3 July 2026; published in the Official Journal of the EU on 21 September 2026 (Delegated Regulation (EU) 2026/1560), it has been in force since 24 September 2026. The scope of the CSRD results from the ‘Omnibus I’ Directive (EU) 2026/470 of 24 February 2026, applicable to financial years beginning on or after 1 January 2027 (first reports in 2028). Each development is tracked and dated in our regulatory news.
Frequently asked questions
Do you need to produce a VSME/VS report and a CSRD report?
No, these are not two cumulative obligations. A company that falls within the mandatory scope of the CSRD reports under the ESRS; VSME/VS is aimed at companies that are outside that scope and choose lighter, voluntary reporting. You therefore do not do both: either you are subject to one or you opt for the other. To find out which side you are on, see the pillar page VSME/VS standard: who is it for.
Does VSME/VS replace EcoVadis?
No, because the two do not play the same role. EcoVadis is a third-party rating; VSME/VS is a reporting framework that the company completes itself. A VSME/VS report will not give you an EcoVadis score, but it brings together structured data that can make it easier to respond to an EcoVadis questionnaire or any other customer request.
Is VSME/VS a legal obligation?
No. As things stand on 8 November 2026, VSME/VS is voluntary: it entails no penalty and no mandatory filing. It may nevertheless become commercially necessary when a customer, a bank or a call for tenders requires ESG data. This topic is covered in the pillar page VSME/VS and financing and in VSME/VS and the value chain.
Where should you actually start?
Once the right framework has been identified, implementation involves choosing the module, collecting the data and building an evidence file. Everything is explained in detail in the guide Applying the VSME/VS standard in SMEs and micro-enterprises, and the available tools (including EFRAG’s official Excel template) are listed in Tools and software for VSME/VS reporting. An accounting firm can also support the process, as explained in the pillar page VSME/VS: a new service line for accounting firms.
