Leading SME ESG reporting platforms

No. VSME itself remains voluntary for the SME choosing whether to report. However, as of July 3, 2026, the EU Commission adopted a binding delegated act — sometimes now called the “VS” (Voluntary Standard) — built on the VSME framework. While an SME still isn’t required to report, the standard is now legally binding on the other side of the relationship: large CSRD-obligated companies are no longer allowed to request more sustainability data from smaller suppliers than what VSME/VS covers. In practice, this makes VSME the de facto ceiling — and often the default request — for any SME being asked for ESG data by a bank or larger customer.

CSRD is the EU’s binding sustainability reporting law, backed by the detailed ESRS disclosure standards, and applies to large companies. ESRS is the mandatory framework for CSRD-obligated companies with over 1,000 employees and €450 million in revenue, while VSME is a voluntary, modular standard for SMEs and midcaps below that threshold — with fewer data points and, notably, no external verification requirement. VSME was deliberately built as a lighter-weight version of the same underlying logic, so a company using it now can transition into full ESRS reporting later without starting from scratch.

Following the EU’s Omnibus I simplification package, the voluntary standard now serves as the reference framework for non-listed companies with up to 1,000 employees and €450 million in annual turnover. Even companies in the 250–999 employee range that were exempted from mandatory CSRD reporting still face real pressure from large corporate buyers and banks demanding sustainability data as a condition of doing business. If your company falls into that gap — too small for CSRD, but still being asked for ESG data — VSME software is built specifically for you.

No. Unlike ESRS, VSME carries no external verification requirement — you can complete and publish a VSME report without engaging an accredited assurance provider. This is one of the standard’s core design goals: giving SMEs a credible, structured way to report without the cost and complexity of a formal audit process.

Pricing varies widely depending on scope. Pure-play VSME tools built specifically for the standard — like ExecutESG and ESG Lift — range from free entry-level tiers up to roughly €600–2,000 a year. Broader carbon accounting and multi-framework platforms that include VSME as one module among several — like GoClimate, Greenly, and Coolset — typically run from a few hundred euros a month up to several thousand a year, reflecting their wider scope beyond VSME alone.

VSME environmental disclosures map closely to established GRI standards — corresponding to GRI 302, 303, 304, 305, 306, and 301 — while social disclosures align with GRI 401, 403, 404, and 405, giving companies already familiar with GRI reporting a meaningful head start. The Basic Module covers a small set of core disclosures — energy use, emissions, workforce data, and basic governance — while the Comprehensive Module adds further detail for companies facing more demanding stakeholder requests.
