VSME Ireland SME Guide

Your clients are asking for sustainability data. VSME is the answer.

If you run an Irish SME and you have received a questionnaire from a large client asking about your carbon footprint, energy use, or ESG practices — you have already felt the ripple effect of the EU's Corporate Sustainability Reporting Directive (CSRD). Large Irish and EU companies subject to CSRD need sustainability data from their suppliers to complete their own Scope 3 reporting. That data request landed in your inbox.

Until recently, these requests came in inconsistent formats — different clients asking for different data in different ways. The VSME standard — Voluntary Sustainability Reporting Standard for SMEs — is the EU's answer to that inconsistency. It is a standardised framework that tells Irish SMEs exactly what to report, in a format that works for every client asking.

This guide explains what VSME is, what it requires, and the practical steps Irish SMEs should take now.

What is VSME?

VSME stands for Voluntary Sustainability Reporting Standard for SMEs. It was developed by EFRAG — the European Financial Reporting Advisory Group — and delivered to the European Commission in December 2024. In July 2025, the Commission officially recommended that SMEs adopt it and that large companies and banks base their ESG data requests on it wherever possible.

In February 2026, the Omnibus I Directive went further — it made VSME the statutory 'Value Chain Cap', legally limiting what CSRD-reporting companies can ask from their SME suppliers to the VSME datapoints. In plain terms: if a large client sends you a sustainability questionnaire that goes significantly beyond VSME, they are asking for more than the law allows.

VSME is now the standard common language for sustainability data exchange between large companies and their SME suppliers across Ireland and the EU.

Who does VSME apply to?

VSME is designed for non-listed SMEs with fewer than 250 employees, annual turnover not exceeding €50 million, or a balance sheet total not exceeding €43 million. It is voluntary — no Irish SME is legally required to file a VSME report. But the practical pressure to adopt it is real and increasing from three directions:

• Large corporate clients subject to CSRD need your Scope 3 data and are basing requests on VSME datapoints
• Banks and lenders are integrating VSME-aligned ESG criteria into lending decisions and credit assessments for Irish SMEs
• Public procurement and tender requirements are increasingly asking for structured sustainability data from suppliers

The Omnibus I reform in February 2026 narrowed mandatory CSRD significantly — most Irish SMEs are now outside mandatory scope. But that did not reduce the supply chain pressure. The large Irish companies still subject to CSRD still need your data. VSME is simply the agreed format for providing it.

What does VSME actually require?

The VSME is structured in two modules — Basic and Comprehensive. Most Irish SMEs should start with the Basic Module.

The Basic Module has 11 disclosure requirements covering three areas:

• Environment: Energy use, Scope 1 and 2 emissions, carbon intensity, waste management, water use, and pollution risk. This is the data your CSRD-reporting clients need most urgently for their own Scope 3 inventory.
• Social: Workforce headcount, gender breakdown, employee turnover, health and safety incidents, and working conditions.
• Governance: Business structure, sector, size, and any sustainability certifications your business already holds.

The good news: most of this data already exists in your business. Energy bills, HR records, and company accounts contain the vast majority of what the Basic Module requires. The challenge is structuring it into a format that is traceable, consistent, and shareable with multiple clients.

The Comprehensive Module adds nine further disclosures — including emission reduction targets, transition plans, climate risk analysis, and detailed governance disclosures. This level is primarily for SMEs supplying to banks with active regulatory reporting obligations or investment funds with ESG mandates. For most Irish SMEs in corporate supply chains, the Basic Module is the starting point and the immediate priority.

Most Irish SMEs can prepare their Basic Module VSME report using data they already hold — energy invoices, HR records, and company accounts. The gap is structure and traceability, not data.

VSME vs CSRD — what is the difference?

Irish business owners often hear both terms and confuse them. The distinction is straightforward:

• CSRD (Corporate Sustainability Reporting Directive): Mandatory for large companies meeting two of three thresholds (1,000+ employees, €450M+ turnover, €375M+ balance sheet under Omnibus I). Requires full European Sustainability Reporting Standards (ESRS) — 80+ disclosure requirements. Not applicable to most Irish SMEs.
• VSME (Voluntary Sustainability Reporting Standard): Voluntary for non-listed SMEs under 250 employees. 11 disclosures in the Basic Module. Designed to be achievable without a sustainability team. This is the framework most Irish SMEs will use.

If your business is in the supply chain of a CSRD-reporting company, VSME is what they are (or soon will be) requesting from you. It is not CSRD-lite — it is a purpose-built, proportionate framework that gives large companies what they need from suppliers without burdening smaller businesses with disproportionate reporting.

What Irish SMEs should do now — a practical checklist

You don't need to file a VSME report today. But building the data infrastructure now means you can respond to client requests quickly, accurately, and with credibility. Here is where to start:

• Identify whether you have received sustainability data requests from clients. If you have, note what was asked. Chances are it maps closely to VSME Basic Module datapoints — energy, emissions, workforce.
• Start measuring Scope 1 and 2 emissions. This is the environmental core of the Basic Module and the data your CSRD-reporting clients need most urgently. Scope 1 is direct emissions from fuel, gas, and company vehicles. Scope 2 is your purchased electricity.
• Collect 12 months of energy data. Gather electricity, gas, and fuel invoices for the last full financial year. This is the starting point for both your carbon footprint and your VSME environmental disclosures.
• Use a structured tool rather than a spreadsheet. VSME requires that data be traceable and consistent — shareable with multiple clients in a standardised format. A spreadsheet cannot provide the audit trail that gives your data credibility. A carbon accounting platform built for SMEs can.
• Talk to your accountant. Irish accountancy practices are increasingly advising clients on VSME and CSRD supply chain obligations. If your accountant has not raised this yet, ask them about it. See our Ireland carbon accounting page for further context.

GreenKPO produces the structured, audit-ready emissions data that forms the environmental core of a VSME Basic Module report — Scope 1 and 2 calculated, tagged, and traceable. Most Irish clients complete their first report within a working week.

Why starting now matters

The Irish SMEs that build clean, structured carbon data in 2026 will have two years of comparable baseline data when client requests intensify in 2027 and 2028. Those that wait will be scrambling to produce historical data retrospectively — a significantly harder and more expensive problem.

VSME is also increasingly being used as a competitive signal beyond supply chain compliance. Irish SMEs with credible ESG data are better positioned for green finance, government procurement tenders, and ESG-conscious international clients. Starting early is not just about compliance — it is about competitive advantage.

The European Commission has made clear that VSME is the framework it wants Irish SMEs to use. The tools are free, the digital template is published, and the data most Irish SMEs need to report already exists in their business. The only question is whether it is structured and traceable. GreenKPO makes it both.
