VSME Standard: Complete Guide for European SMEs (2026) | CORE

The VSME standard from EFRAG provides a proportionate sustainability reporting framework for European SMEs. This comprehensive guide covers everything you need to know to get started.

What is the VSME Standard?

The Voluntary Sustainability Reporting Standard for non-listed SMEs (VSME) is a landmark framework published by the European Financial Reporting Advisory Group (EFRAG). Designed specifically for small and medium-sized enterprises, the VSME provides a proportionate and accessible pathway to sustainability reporting that acknowledges the resource constraints of smaller businesses.

In the European Union, SMEs represent over 99% of all businesses, employ approximately 100 million people, and generate more than half of the EU's GDP. Despite their collective significance, these organisations have historically lacked a sustainability reporting framework tailored to their needs. The VSME fills this gap.

Why the VSME Matters in 2026

The year 2026 marks a critical inflection point for sustainability reporting in Europe. Large companies subject to the Corporate Sustainability Reporting Directive (CSRD) are now actively collecting data from their supply chains, which inevitably flows down to SME suppliers. Banks are integrating ESG criteria into lending decisions. Public procurement increasingly weighs sustainability performance.

Even though the VSME is voluntary, market forces are making it a de facto requirement for many SMEs. Companies that adopt it early gain a competitive advantage in terms of market access, financing, and stakeholder trust.

The Three-Module Structure

The VSME is built on a modular approach that allows progressive adoption:

Basic Module

The entry point for any SME. It contains just 11 essential datapoints covering:

Energy: Total energy consumption in MWh
GHG Emissions: Scope 1 and Scope 2 emissions in tonnes CO2e
Workforce: Total employees by gender and contract type
Governance: Basic information on sustainability governance structure

These datapoints are designed to be collectible from existing data sources, requiring minimal additional effort. Most SMEs already track energy bills and payroll data — the Basic Module simply structures this information.

Narrative-Policies Module

This module adds qualitative disclosures on:

Sustainability strategy and objectives
Environmental and social policies
Simplified materiality assessment
Risk management approach
Stakeholder engagement practices

It is suitable for SMEs that want to demonstrate ESG maturity beyond raw data. The narrative approach allows companies to explain their context and commitments without excessive quantitative requirements.

Business Partners Module (Comprehensive)

Designed for SMEs that are suppliers to CSRD-reporting companies. It includes more specific datapoints aligned with the value chain reporting requirements of the ESRS:

Detailed emissions data including relevant Scope 3 categories
Supply chain due diligence information
Product lifecycle environmental data
Workforce health and safety metrics

While more demanding than the Basic Module, it remains significantly simpler than the full ESRS.

VSME vs. ESRS vs. GRI: Key Differences

Understanding where the VSME sits relative to other frameworks is essential:

Scope - ESRS: Mandatory for large companies under CSRD; approximately 800+ datapoints - GRI Standards: Voluntary but widely adopted; modular approach based on material topics - VSME: Voluntary for non-listed SMEs; 11 to approximately 80 datapoints depending on module

Materiality - ESRS: Requires double materiality assessment (financial and impact) - GRI: Requires impact materiality assessment - VSME: Simplified materiality in Narrative module; Basic module uses predefined datapoints

Assurance - ESRS: External assurance required (limited initially, reasonable eventually) - GRI: Assurance recommended but not required - VSME: No assurance requirement, though recommended for credibility

How to Get Started: A Practical Roadmap

Phase 1: Assessment (Month 1-2)

Start with a gap analysis. Map your existing data sources against the VSME Basic Module datapoints. Identify what you already track, what requires new processes, and what tools you need.

CORE's sustainability consultants can conduct this initial assessment, providing a clear picture of your readiness and a tailored implementation plan. Learn more at /servicos/sustentabilidade/vsme.

Phase 2: Data Collection (Month 2-4)

Establish data collection processes for the missing datapoints. For most SMEs, this involves:

Setting up energy consumption tracking (monthly readings from utility bills)
Calculating GHG emissions using recognised conversion factors (e.g., DEFRA, GHG Protocol)
Structuring workforce data from HR systems
Documenting governance arrangements

Phase 3: First Report (Month 4-6)

Compile the data into a structured report. The VSME does not prescribe a specific format, but EFRAG provides templates that facilitate consistency and comparability.

Phase 4: Progressive Enhancement (Year 2+)

Based on stakeholder feedback and business needs, progressively adopt the Narrative-Policies Module and, if relevant, the Business Partners Module.

Common Challenges and Solutions

"We don't have the data" Start with what you have. Energy bills, payroll records, and basic governance documents already contain most Basic Module datapoints. The gap is usually smaller than expected.

"We don't have dedicated staff" The VSME was designed for organisations without sustainability departments. A single person dedicating 2-3 days per month can manage Basic Module reporting. For more comprehensive modules, consider engaging external consultants like CORE.

"Our clients haven't asked yet" They will. Companies reporting under the CSRD are progressively extending data requests to their value chains. Early adoption positions your company as a proactive and reliable partner.

"It's voluntary, so why bother?" Voluntary today does not mean irrelevant. EU regulatory trends consistently move from voluntary to mandatory. Early adopters build capability and avoid the scramble when requirements tighten.

The European Context: National Variations

While the VSME is an EU-level standard, national contexts matter:

Portugal: Strong push through CMVM and Banco de Portugal guidance. CORE operates extensively in this market — see our Portuguese-language resources at /insights.
Spain: Alignment with the Ley de Economia Sostenible and growing demand from large enterprises.
France: Building on the existing Duty of Vigilance framework and DPEF requirements.
Germany: Integration with the Lieferkettensorgfaltspflichtengesetz (Supply Chain Due Diligence Act).

Conclusion

The VSME standard represents the most significant development in SME sustainability reporting in Europe. By providing a proportionate, modular framework, it enables millions of smaller businesses to participate meaningfully in the sustainability reporting ecosystem.

The key to success is starting early, starting simple, and building progressively. CORE has extensive experience guiding European SMEs through this journey. Contact us to discuss how we can support your VSME implementation.
