HOW IT WORKS
Four steps and their record in the evidence package
Each step's panel is rebuilt for this page; its values come from the synthetic sample package.
STEP 01 · COLLECTION
Data and source document
Activity data and its document enter one record.
- The installation and the period are required
- The document is carried with its body
- Doğal gaz tüketimi (biyet ısıtma + yaşlandırma fırını)edge meter · SAYAC-NG-0118.400 Sm³1 April 2027
- Girdi alüminyum biyet kütlesiERP · KANTAR-0224,1 t1 April 2027
- Üretilen profil kütlesiMES · MES-HAT-122,4 t1 April 2027
STEP 02 · CALCULATION
Calculation bound to a version
The calculation runs under the selected methodology pack version; each step is recorded in the lineage.
- The version is written onto the result
- Regime rules are kept separate
Methodology pack
cbam/aluminium-extrusion
- Version
- 2027.01.1
- Effective from
- 1 January 2027
- Legal basis
- 3 provisions
The methodology pack is content-addressed JSON; a cyclic dependency or an unregistered operation is rejected at load time.

- 02Doğrudan emisyonlar (yakıt yanması)39,018672 tCO₂e
- 03Biyet gömülü emisyon yoğunluğu3 tCO₂e/t
- 04Öncül madde emisyonları72,3 tCO₂e
- 05Toplam gömülü emisyon111,318672 tCO₂e
STEP 03 · SEALING
Seal root
Four calculation leaves reduce to one seal root.
- The daily root is anchored to an external timestamp
- The timestamp token and the certificate chain are retained

If any one of the four calculation leaves changes, the seal root changes; if the root changes, the seal no longer holds.
STEP 04 · PREPARATION
Verifier opinion and period archive
The verifier's opinion is bound to the package; the period archive is exported.
- The verifier reads within the grant scope
- No signature is produced on the server

THE RECORD IN THE PACKAGE
Step, field and its counterpart in the seal
Each step writes a field into the evidence package; that field has a counterpart in the seal.
| STEP | WRITTEN INTO THE PACKAGE | COUNTERPART IN THE SEAL |
|---|---|---|
| 01Collection | inputs · sources · documents | inputSetHash · sourcesHash · document.hash |
| 02Calculation | methodologyPack · lineage | methodologyHash · lineageHash |
| 03Sealing | seal.sealFormat · seal.sealedAt | seal.merkleRoot |
| 04Preparation | attestations | attestation.merkleRoot |
The field names are the evidence package's own keys.
Founding customer package
The package covers one installation and the 2026 period.
