In short
- The ladder is audited and buys you a tender advantage. VSME is self-declared and answers customer data requests.
- Neither replaces the other, but one emissions inventory can feed both if the boundary is set once.
- The EU value chain cap does not reach a Dutch tender requirement, because a tender is procurement, not CSRD reporting.
One is an audited Dutch certification that changes your score in a public tender. The other is a voluntary EU reporting standard that answers a customer's data request. They get confused constantly, usually by companies that need both, and the confusion is expensive because the two are bought by different people for different reasons. The good news is that the slowest component, a defensible greenhouse gas inventory, is shared. Decide the boundary once and you can serve a certifying auditor and a corporate customer from the same underlying numbers.
What is each one?
The CO2-Prestatieladder is a Dutch certification scheme. You certify to a tier, a third party audits you against the scheme handbook, and the certificate gives you an award advantage in Dutch public procurement. It is long established: ProRail has awarded on it since 1 December 2010 and Rijkswaterstaat moved to Handboek 4.0 on 1 July 2026, applying 2, 4 and 6 percent. ProRail switches on 1 January 2027 with a proposed 4, 7 and 10 percent it calls provisional. 14 January 2027 is the last date on which a contracting authority may tender with gunningscriterium 3.1 and the last on which a 3.1 audit may be performed, so a certified organisation switches at its first audit after that, and the migration has a fixed deadline rather than being done at leisure. Existing 3.1 certificates can stay valid until 14 January 2028. The tier structure, the requirements at each tier and the audit process are all set by the scheme owner, so read the current handbook rather than any summary of it, including this one.
VSME is a reporting standard developed by EFRAG at the European Commission's request and delivered in December 2024. It has a basic module and a comprehensive module, and reporting the basic module is a prerequisite for the comprehensive one. Its only standing in EU law today is Commission Recommendation (EU) 2025/1710 of 30 July 2025, which is non-binding and states that there is no obligation to provide assurance on information reported by non-listed SMEs and that a self-declaration by the SME is sufficient.
So one of these ends in an auditor signing something. The other ends in you signing something.
Who asks for each, and why?
The ladder is asked for by a public buyer, in a tender, on a deadline you did not choose.
The commercial logic is unusually clean. A fictitious reduction is a discount applied to your bid for scoring purposes, so a higher tier makes your price look lower against a competitor's without you touching your margin. That is one of very few sustainability certifications where the return can be calculated directly: take the fictitious reduction at the tier you are considering, apply it to the value of the tenders you bid on in a year, and compare that with what certification and its audit cost you. For contractors bidding regularly into Dutch public work, the arithmetic is rarely close. We cover the scheme itself for smaller firms in the CO2-Prestatieladder for SMEs.
VSME is asked for by a large corporate customer that is itself reporting. Since Directive (EU) 2026/470 of 24 February 2026, CSRD reporting applies only to undertakings exceeding both EUR 450 million of net turnover and an average of 1,000 employees, for financial years starting on or after 1 January 2027. Those companies have to report value chain information, so they ask suppliers, and the voluntary standard is the format they are being pointed at. There is no deadline, no scoring and no certificate. There is a relationship, and a questionnaire that arrives every year.
How do they compare, line by line?
| Dimension | VSME | CO2-Prestatieladder |
|---|---|---|
| What it is | A voluntary EU reporting standard from EFRAG | A Dutch certification scheme with tiers |
| Standing | Carried by non-binding Commission Recommendation (EU) 2025/1710 | A private scheme, recognised by Dutch public buyers |
| Who asks | A customer in CSRD scope needing value chain data | Public buyers. ProRail has awarded on it since 2010; Rijkswaterstaat moved to version 4.0 in July 2026 |
| Verified by whom | Nobody. Self-declaration is sufficient | A third-party audit against the scheme handbook |
| What you get | A reusable report you send to any customer | A certificate at a tier, and an award advantage |
| Direct commercial value | Keeps a customer relationship, replaces bespoke questionnaires | A fictitious reduction on your bid price, set per authority: 2, 4 and 6 percent at Rijkswaterstaat |
| Effort profile | Emissions calculation first, then annual refresh | Emissions calculation plus policy, targets and measures, then audit |
| Hard deadline | None. Practical timing follows your customers' reporting cycle | Yes. 14 January 2027 is the last day an authority may tender with 3.1, and you switch at your first audit after it |
| Covers more than emissions | Yes, environment, social and governance disclosures | Yes, including policy, targets and communication |
| Capped by the EU value chain cap | Yes for CSRD reporting requests, once the cap is transposed by 19 March 2027 | No. A tender requirement is procurement |
| Does it satisfy the other | No | No |
Does one satisfy the other?
No, in both directions, and it is worth being precise about why.
A certificate is not a report. Handing a customer your ladder certificate in answer to a value chain data request gives them a tier, not a tonnage they can consolidate. They need scope 1, scope 2 and the scope 3 categories that matter to them, on a stated boundary, in a form they can add to their own figures.
A report is not a certificate. Sending a public buyer your self-declared VSME report in place of a ladder certificate gives them a document nobody audited, in a scheme they do not score on. The tender will not award on it.
What is genuinely shared between them?
The inventory, which is most of the work.
Both need scope 1 and scope 2 for a stated reporting period, on a boundary that names the legal entities and sites included, calculated with a method you can point at and source records you can retrieve. Both are annual, and both are worth more as a series than as a single year. Both fall over for the same reason, which is a method that changed between years because somebody switched tools or switched factor sets, leaving reduction unprovable and comparison meaningless.
That is the practical argument for deciding the boundary once, before either process starts, rather than letting the tender define it in March and the customer questionnaire redefine it in September. If you are starting from nothing, carbon footprint consulting is the shortest route to a boundary that survives both.
Where they diverge is the standard of proof. An auditor will ask how a figure was derived, which means traceability from source record to factor to entry is not optional. A corporate customer usually will not ask, until the year they do.
Does the value chain cap apply to a Dutch tender?
No, and companies keep hoping otherwise.
Directive (EU) 2026/470 gives an undertaking in a reporter's value chain averaging up to 1,000 employees a statutory right to decline information exceeding the voluntary standard, and makes any contrary contract clause non-binding. That right arrives through national law, and Member States have until 19 March 2027 to transpose it. But even once it has, it applies only to information gathering for the purpose of sustainability reporting under the Accounting Directive. It does not restrict due diligence requests, risk management requests or ordinary commercial questions.
A public buyer's tender requirement is procurement. So is a scheme's certification requirement. Neither is inside the cap, and neither can be declined on that basis. The distinction is worth learning properly, because it is the difference between a defensible refusal and a lost bid. We set it out in which ESG questions you can decline.
Which do you need, and when?
If you bid on Dutch public work, the ladder, and the migration deadline sets your calendar for you rather than the other way round.
If your revenue is concentrated in large corporate customers, VSME, timed so the report exists before the questionnaire arrives rather than after. The standard itself is covered in what VSME is and what your customer may actually ask for, and if you want the report produced rather than explained, that is VSME consultancy.
If both describe you, which is common for Dutch contractors and installers with a mix of public and corporate work, build the inventory to the stricter standard. Building for an auditor and reusing for a customer works. The reverse does not.
Our own platform names the CO2-Prestatieladder as a reporting output alongside PPN 006 and the GHG Protocol, so the same inventory produces both. One honest limit: it does not forecast. A small business customer said as much on G2 in August 2026, and we told them it is on the development list. If your ladder work depends on modelling a reduction trajectory rather than recording one, plan that part elsewhere for now, or book a call and we will be straight with you about the gap.
