In short
- Most of VSME is policy description. The emissions disclosure is the part that needs actual data.
- VSME caps what large customers may demand from SME suppliers, which is its most useful feature.
- Report once, reuse across customers. That is the entire point of the standard.
Most of a VSME report can be written from what you already know about your business. The greenhouse gas disclosure is the exception, because it needs a calculation rather than a policy statement. That is the part software is for, and it is the part with the longest lead time.
VSME is the EU's voluntary sustainability reporting standard for non-listed SMEs, developed by EFRAG. It also sets a cap on how much sustainability information large CSRD-reporting companies may demand from SME suppliers, which is the part most coverage underplays and the part that matters commercially.
Who actually needs this, and when?
The practical trigger is a customer, not a regulator. VSME is voluntary. Nobody will fine you for not doing it.
What happens instead is that your large customers stay in CSRD scope under the revised thresholds, above 1,000 employees and EUR 450 million turnover, for financial years beginning on or after 1 January 2027. They have to report on their value chain. So they ask you.
That means the questions intensify through 2027 as in-scope customers assemble value chain data for their first reports under the revised scope. There is a seasonal pattern worth planning around: supplier questionnaires cluster in the first quarter, after large companies publish annual reports and start collecting for the next cycle.
The practical window to have a report ready is during 2027, not when the request lands. We go through the standard itself in what VSME is and what your customer may actually ask for.
What does the emissions disclosure need?
The environmental disclosures are where real data is required, and the greenhouse gas figure is the one that needs a calculation.
Scope 1 and scope 2 as a minimum. Direct emissions from fuel you burn and vehicles you run, plus purchased electricity and heat.
Scope 3 where your customers ask for it. VSME does not require full scope 3 in the basic layer, but the customer sending you a questionnaire frequently does. If your customers are pushing on value chain emissions specifically, scope 3 is where the questions are heading and it is worth scoping early.
A method you can repeat. VSME reporting is annual, and a report is worth considerably more when the year-on-year series is consistent. Rebuilding the calculation from scratch each year produces numbers that cannot be compared to last year's, which defeats most of the purpose.
That repeatability argument is the real case for a platform over a spreadsheet or a one-off consultancy engagement. Not that the first calculation is easier, but that the second and third are.
What is the value chain cap, and why does it matter?
This is the provision worth understanding properly, because it changes the conversation with your customer.
The cap limits the sustainability information that CSRD-reporting companies may require from suppliers in their upstream and downstream value chain, and it became considerably stronger in 2026. Directive (EU) 2026/470 turned it from a limit written into the standards into a statutory right belonging to the supplier. An undertaking averaging no more than 1,000 employees in the preceding financial year, sitting in the value chain of a reporting company, is a protected undertaking with the right to decline information beyond what the voluntary standard specifies. A contract clause that says otherwise is not binding. The reporting company also has to tell you which of its requests exceed the standard and that you have the right to refuse them.
Three honest qualifications. The right is written to apply from financial years beginning on or after 1 January 2027, the directive has to be transposed into national law by 19 March 2027, and the delegated act that fixes what the voluntary standard actually contains was adopted on 3 July 2026 but was still in scrutiny in late August 2026. So the shape is settled and the detail is not quite.
The cap also covers one thing only: information gathering for sustainability reporting under the Accounting Directive. It does not restrain due diligence questions, risk management questions, or a customer simply asking you something as a commercial matter. Knowing which kind of request you are holding is the whole skill, and we go through it in refusing ESG questions.
For an SME receiving questionnaires the practical effect is the same as before, only firmer: report once, point customers at it, and decline what sits beyond the line.
Software matters here in a specific way: the value of reporting once depends on being able to hand the same underlying numbers to every customer who asks, in whatever format each one wants. That is an export problem, not a calculation problem, and it is worth testing before you buy.
What should you look for in a tool?
Five things, in the order they will bite you.
Can it produce scope 1 and 2 from the data you actually have? Fuel cards, energy bills, mileage. Not from data you would have to start collecting.
Can it add scope 3 categories selectively? You want the ones your customers ask about, not all fifteen.
Does it keep the method stable year on year? Ask directly what happens when emission factors update, and whether you can restate a prior year while keeping the original.
Can it export to an arbitrary customer template? Every large customer has its own spreadsheet. Test this with a real one.
What does it cost in year two? Carbon reporting is an annual routine. A first-year discount that resets changes the real cost materially.
What does Hedgehog do for VSME?
The platform guides you through the GHG Protocol, building a data collection plan and a GHG inventory, with an AI guide for setup and human GHG experts reachable in-app. It covers over 20,000 spend-based and activity-based factors and lets you add organisation-specific or supplier-specific data. Reporting outputs include the GHG Protocol, PPN 006 and the CO2-Prestatieladder.
Free account with no sales call. Pro from EUR 1,200 per year.
Two honest limits for anyone reading this with VSME specifically in mind.
Hedgehog covers the emissions disclosure, not the whole standard. VSME spans social and governance disclosures too. The platform does not write those for you, and if you want a broad ESG reporting suite, one of our customers rated us 3.5 out of 5 on G2 and said exactly that in June 2026. For the full report, that is what VSME consultancy is for.
Loading data takes work. A reviewer said in August 2026 that once the data is in, everything works perfectly, and getting it in is the challenging part. Budget for that honestly. It is the single most underestimated line in every carbon reporting project.
What should you do first?
If customers are already asking, start with the emissions calculation. It has the longest lead time and everything else in a VSME report is faster.
If they are not asking yet but your customers are large, find out which of them remain in CSRD scope under the revised thresholds. That tells you who will ask and roughly when, which is enough to plan the year.
Either way, you can start a free account and get a first scope 1 and 2 number without talking to anyone.
