VSME Sustainability Reporting: A Practical Guide for SMEs

If you are stepping back to ask whether your company needs sustainability reporting at all, start with our broader piece on sustainability reporting for SMEs — it covers who has to report, who is being asked anyway, and how that pressure ended up on SME desks. This guide goes deeper on the standard itself.

If you run finance, operations, or sustainability at an SME, you have probably been forwarded an ESG questionnaire by a bank or a large customer in the past twelve months. VSME is the answer to that questionnaire.

EFRAG published the Voluntary SME Sustainability Reporting Standard (VSME) so that non-listed small and medium-sized companies can produce one sustainability report that satisfies the data demands flowing down from CSRD-in-scope partners — instead of filling out a different spreadsheet for every counterparty.

This guide walks through what VSME actually requires, how Basic and Comprehensive differ, and the order we recommend tackling disclosures in.

Why VSME exists

CSRD pulled roughly 50,000 large EU companies into mandatory ESRS reporting. Those companies need ESG data from their suppliers and portfolio companies — most of whom are SMEs. Without a standard, every large counterparty was inventing its own questionnaire.

VSME standardises the request. A single VSME report — Basic or Comprehensive — is intended to be proportionate, voluntary, and sufficient to answer typical data asks from:

• Banks running ESG-linked lending checks
• Insurers underwriting commercial policies
• Large customers under CSRD pressure on Scope 3
• Private-equity holders consolidating sustainability KPIs

Module Basic vs Module Comprehensive

VSME is split into two modules. You choose Basic, Comprehensive, or Basic-now-Comprehensive-later.

Module Basic — minimum viable disclosure

Designed for any SME, even microenterprises. Disclosures are limited to data most companies already have:

• General company information (legal form, sector, headcount, locations)
• Energy and greenhouse gas (Scope 1 + 2, location-based)
• Pollution and water reported only if material to the business
• Workforce headcount, gender split, and employment type
• Health and safety incident counts
• Existence (yes/no) of key policies — anti-corruption, human rights

Basic deliberately avoids: targets, double materiality, value-chain data, Scope 3.

Module Comprehensive — adds context and value chain

Builds on Basic and adds:

• Strategy and business model narrative
• Identified material sustainability matters (lighter than ESRS double materiality)
• Targets and transition plan elements where they exist
• GHG Scope 3 categories where data is available
• Workforce details: training hours, collective bargaining coverage, pay gap
• Value-chain workers and affected community policies
• Human rights due-diligence narrative

Comprehensive is what you reach for when a major customer or investor explicitly asks for it, or when you are preparing the company for CSRD scope in two to three years.

How to start

We see SMEs make the same mistake: they try to design a Comprehensive report from day one, drown in scope, and ship nothing. The faster path:

1. Inventory what you already have. HR exports, utility invoices, payroll, incident logs, supplier contracts. 80% of Basic is already in your systems.
2. Pick Basic. Lock the scope. Resist scope-creep into Scope 3 and targets in the first cycle.
3. Identify the data owner per disclosure. One named person per row. No “the team” entries.
4. Draft, then review with finance. VSME reports get audited by banks even when not formally assured — finance discipline matters from day one.
5. Decide on Comprehensive only after Basic is shipped and you know which counterparties asked for more.

What VSME does not solve

VSME is not a shortcut around the EU Taxonomy, SFDR pass-through requests from financial counterparties, CBAM, or sector-specific obligations. If you are a manufacturer with imports of steel, aluminium, cement or fertiliser, CBAM applies regardless of VSME. If your bank is SFDR Article 8/9, it will still ask for taxonomy-aligned revenue and CapEx — VSME Comprehensive helps but does not fully replace it.

Treat VSME as the default chassis. Bolt on the sector- or counterparty-specific disclosures only where they are demanded.

Where this leaves you

If a counterparty has asked you for ESG data in the last six months, you almost certainly want VSME Basic in production this year. If you already produce a sustainability summary for your website or annual report, switching it to the VSME structure costs you a few weeks and saves you years of bespoke questionnaire pain.

Future posts in this series will cover Module Basic disclosure-by-disclosure, double materiality for Comprehensive, Scope 3 calculation methods for SMEs, and how to map your existing evidence to VSME line items without rebuilding your data stack.
