What if a supplier isn't on the platform?

Coverage grows as more organisations and suppliers join the ecosystem. For suppliers not yet on the platform, spend-based estimates can be used as a starting point, with the path to actual data clearly defined.

How does this help with Scope 3 reporting?

Supplier data in the ecosystem feeds directly into Scope 3 Category 1 calculations. Every figure is traceable from the supplier's source record through to your emissions disclosure.

What standards are used for classification?

All supplier data is classified to UNSPSC, providing a shared canonical standard across all suppliers and customers regardless of industry, geography, or local practice.

Does this replace supplier questionnaires?

Yes. Instead of sending questionnaires each cycle and reconciling inconsistent responses, you access structured, comparable data that suppliers maintain once in the ecosystem.

Supply chain due diligence that doesn't depend on suppliers doing you a favour

Most supply chain sustainability programmes run on questionnaires, follow-up emails, and goodwill. When the data comes back inconsistent and incomplete, the problem isn't supplier engagement. It's the process.

The challenge

Due diligence built on questionnaires fails before it starts

Commercial pressure skews responses

Suppliers prioritise responses based on commercial pressure — the biggest customers get complete answers while others receive partial data or nothing. You're really measuring your leverage, not actual performance.

Inconsistent formats, manual reconciliation

Every customer uses different questionnaires and suppliers answer inconsistently, with metrics reported in different units and terminology. Manual reconciliation reintroduces the subjectivity due diligence should eliminate.

Effort doesn't compound

Each assessment cycle doesn't build on the last — the effort required to gather and standardise data remains constant rather than improving over time.

The approach

Supply chain due diligence needs a shared data standard, not a better questionnaire.

The ecosystem model replaces questionnaire-based due diligence with structured data that suppliers contribute once — and that every customer can access, on a shared standard, without additional requests.

Klappir's ecosystem is a shared data infrastructure. When a supplier connects to the platform, they contribute their operational and sustainability data once — classified against a common standard (UNSPSC), with traceability from source to figure. That contribution becomes available to every customer who works with that supplier.

No questionnaires. No chasing. No manual reconciliation across different formats. The supplier fills in their data once and maintains it. The organisation accesses structured, comparable data whenever they need it — for Scope 3 calculations, CSRD value chain reporting, or internal due diligence reviews.

As more organisations and suppliers join the ecosystem, coverage improves automatically. Data quality compounds with scale — without additional effort from any individual participant.

How it works

What changes when supplier data lives in a shared infrastructure

Data collection

Typical approach: Questionnaires sent to each supplier per reporting cycle; responses collected manually. With Klappir: Suppliers contribute structured data once to the ecosystem; it's reused across all customer relationships.

Data consistency

Typical approach: Each supplier uses their own formats and units; reconciliation is manual. With Klappir: Every supplier record classified to a shared standard (UNSPSC) automatically.

Audit trail

Typical approach: Questionnaire responses stored separately with no traceability to underlying operations. With Klappir: Every figure traceable from source to Scope 3 calculation with a full audit trail.

Scope 3 coverage

Typical approach: Coverage limited by response rates; gaps filled with spend-based estimates. With Klappir: Supplier data in the ecosystem is available immediately for Scope 3 Category 1 calculations.

Effort over time

Typical approach: Effort is constant — every cycle requires the same chasing, reconciling, and normalising. With Klappir: Supplier data maintained once; coverage and quality improve as the ecosystem grows.

Value chain reporting

Typical approach: Value chain disclosure assembled from incomplete, inconsistent inputs. With Klappir: Structured supplier data feeds directly into CSRD value chain reporting without additional collection effort.

Common questions about supply chain due diligence

Answers to the questions we hear from organisations evaluating supply chain sustainability data.

Suppliers join the Klappir ecosystem and contribute their operational and sustainability data once, classified against a shared standard. This data is then available to every customer who works with that supplier.
