VSME Explained: The Voluntary Standard Becoming the EU's De Facto Supplier Form

VSME (Voluntary reporting Standard for SMEs) is a voluntary, lighter EU standard for companies under 1,000 employees, with two modules and twenty disclosures, not mandatory, but increasingly used as a standard answer when customers keep asking for sustainability information despite a company not falling under mandatory reporting rules. It gives smaller companies a recognised, standardised way to respond rather than answering every customer's bespoke questionnaire from scratch each time.

Why VSME is becoming a de facto requirement despite being voluntary

Large companies subject to mandatory CSRD reporting need sustainability data from their own suppliers to complete their value-chain disclosures. VSME gives them a standardised format to request, which means smaller suppliers increasingly encounter it as an expectation even though no regulation technically requires them to use it.

What the two modules actually cover

A basic module covering core disclosures most companies can complete relatively quickly, and a comprehensive module for companies wanting to go further, giving smaller companies flexibility in how much detail to provide depending on what their specific customers are asking for.

How VSME protects smaller suppliers from excessive requests

It functions as a practical ceiling: a large customer can reasonably expect VSME-level disclosure from a smaller supplier, but demanding significantly more than VSME defines starts to look disproportionate, giving smaller companies a defensible reference point when a request seems to exceed what's reasonable.
