The VSME Survival Guide

When your largest customer asks for Scope 3 data

For most small and mid-sized suppliers, the first real sustainability deadline does not arrive from a regulator. It arrives in a procurement questionnaire. A long-standing customer sends a supplier assessment, and somewhere on page three is a request for energy consumption, emission figures and a policy document. The response is due in two weeks.

This is the practical shape CSRD has taken for companies that are not themselves in scope. The obligation belongs to the large corporation; the data request lands with its suppliers.

The tender has become the reporting deadline

Large groups reporting under CSRD have to account for Scope 3 emissions, and for most of them the value chain represents the majority of their total footprint. They cannot produce that figure without their suppliers. Two consequences follow, and both are already visible in Nordic procurement:

• Sustainability data has moved from a nice-to-have appendix into scored tender criteria.
• Supplier lists are being consolidated. Where a buyer once managed hundreds of small vendors, chasing data from each one is unmanageable, so the list gets shorter.

A supplier who can answer credibly stays on the list. A supplier who cannot answer, or whose estimates fall apart under a follow-up question, quietly stops being invited.

What VSME actually asks of you

The Voluntary Sustainability Reporting Standard for non-listed SMEs, published by EFRAG, exists precisely to stop this becoming chaos. Rather than every buyer inventing its own questionnaire, VSME defines a common set of disclosures proportionate to a smaller company.

It is built in two modules:

• Basic covers the fundamentals: energy consumption, greenhouse gas emissions, water, waste, and workforce characteristics.
• Comprehensive adds context for companies whose customers or lenders need more: targets, governance practices, and value chain information.

For most suppliers the Basic module answers the majority of what a large customer is asking for. That is the point of it, and it is a far smaller undertaking than the full ESRS regime that applies to the customer making the request.

The gap is rarely data. It is structure.

The common assumption is that answering requires new measurement. In practice most of the underlying data already exists inside the business:

• Energy consumption is on the electricity and heating invoices.
• Fuel use is in the fleet and fuel card records.
• Waste volumes are on the waste contractor’s reports.
• Headcount, turnover and training figures are in payroll and HR systems.

What is missing is structure. The figures sit in four different systems, owned by four different people, calculated to no consistent methodology, with no record of where any given number came from. That is survivable for one questionnaire. It stops being survivable when the same customer asks again next year and expects to see a trend, or when a second customer asks the same questions in a different format.

A practical sequence for the next quarter

Suppliers who handle this well tend to follow roughly the same order of work:

• Establish the boundary first. Decide which legal entities and sites are included before collecting anything. Changing this later invalidates the comparison.
• Start with the Basic module. Treat it as the baseline set of answers, then extend only where a specific customer genuinely requires more.
• Record the source, not just the number. Every figure should be traceable back to an invoice, meter reading or system export. This is the difference between an answer and an auditable answer.
• Assign an owner per data point. Reporting fails far more often on unclear ownership than on methodology.
• Assume it repeats. Build the process so next year is a refresh rather than a restart.

From questionnaire to commercial advantage

There is a version of this where sustainability reporting is a cost imposed by someone else’s regulation. There is another version where a supplier who can answer quickly, consistently and with evidence becomes materially easier to buy from than its competitors.

The difference between the two is almost entirely a question of process. Planmark collects VSME data once, keeps the methodology and the audit trail attached to every figure, and turns the result into a report you can send to a customer without rebuilding it each time the question is asked.
