A reported regulatory value is only as reliable as the documents that support it. Weetra checks whether regulatory data can be traced to the relevant documents, identities, periods and versions.
Regulatory data may come from suppliers, manufacturers, installations, commercial intermediaries, ERP systems, monitoring systems, declarations, certificates and external records. The review asks where the information came from, who produced it, what it relates to, which period and version apply, and whether the different records agree.
A regulatory value can be technically correct and still be difficult to defend if no one can show where it came from. The review therefore starts with the figure or statement being relied on and traces it back to the relevant source records. It asks whether the documents belong to the right product, legal entity, producer, installation, parcel, reporting period or product identifier, depending on the regime.
A document can be genuine and still fail to prove the point it is being used for. The review therefore tests the links between product and supplier, supplier and producer, producer and installation, reported value and source record, and the current file and earlier versions.
Apparently complete files often weaken at those links. A commercial invoice may show a seller but not the manufacturing installation. A supplier declaration may contain a number without showing the record it came from. A revised monitoring plan may exist while the calculation still refers to the previous version. Documentary review checks those connections instead of treating each document as an isolated attachment.
CBAM, EUDR and the Digital Product Passport are different legal systems and do not rely on identical data. But they raise many of the same practical questions: who or what the data refers to, where it came from, how it changed, whether sources conflict, and whether the record can still be understood later.
Goods → producer → installation → reporting period → embedded emissions → source records. CBAM is Weetra’s main operational service.
Product → commodity → production source → geolocation and legality → risk assessment → due-diligence records. The legal duties are different from CBAM.
Product → unique identifier → responsible economic operator → required data field → source system or supplier → version → passport data.
More data-intensive customs and regulatory systems make stable identifiers, clear sources and cross-system checks more important. A digital submission does not remove the need to know where the information came from.
Weetra examines the documents in scope, the information they contain, the links between the relevant actors and goods, the consistency of quantities and periods, competing versions, inconsistencies, corrections and the points the available records still cannot establish.
Source support: which document supports a specific reported figure or statement.
Identity: which legal entity, operator, producer, installation, product, parcel or regulated object the evidence belongs to.
Relationships: whether commercial, production, regulatory and source records point to the same underlying object.
Time and versions: whether periods align and the version used in a calculation or declaration is the applicable one.
Conflicts and unresolved points: where records disagree or the available documents cannot establish the point being relied on.
Review history: what was questioned, replaced or corrected and how the file changed before the conclusion was issued.
A review can produce findings, targeted questions, a Determination issued under professional responsibility and, when the mandate provides for it, a Determination Package showing the documents reviewed, the issues found, the corrections made and the basis of the conclusion. The exact output depends on the mandate and review depth.
Weetra does not turn every documentary problem into the same product. A first check may be sufficient. A deeper engagement may be appropriate when the file contains complex relationships, multiple source systems, unresolved contradictions or high-consequence positions. If no deeper review is required, no further engagement is recommended.
Regulatory files are often revisited long after the original work is finished. Preserving what was received, what changed, what was corrected and what was relied on makes later internal review, professional advice, verification or authority scrutiny much easier.
The point is not to preserve bureaucracy for its own sake. It is to preserve the history needed to understand why a reported figure or statement was accepted, changed, limited or rejected at a particular point in time.
CBAM is Weetra’s main operational focus today. EUDR and Digital Product Passport work are still developing; the site explains their documentary requirements without presenting them as equivalent commercial services.
