Regulatory data must be traceable, reviewable and supported by evidence.
WEETRA examines what a regulatory figure is built on: its documents, its sources, its calculations. We surface what does not hold. An inconsistency, a piece of critical evidence that is missing, a source that cannot carry its claim. And we do it before a file is locked for reporting.
A regulatory value is only as reliable as the evidence behind it.
Reporting now runs on structured data, sources that can be traced, calculations that hold, and a documentary trail someone can actually review. WEETRA checks whether each material value ties back to a source, matches the documents, and, where the data allows, can be recomputed.
Four review objects.
One evidentiary standard.
Source Documents
Documentary source review and validation.
Declared, Extracted & Recalculated Values
Verification of declared values against extracted and recalculated values.
Critical Contradictions & Missing Critical Evidence
Detection and flagging of contradictions and evidence gaps.
Evidence-Chain Integrity
Verification of the integrity and traceability of the evidence chain.

not the outcome.
Pre-Diagnostic
High-level assessment of regulatory exposure and structural readiness.
Initial Documentary Review
First structured review of the documentary base of a dossier.
In-depth Consistency & Defensibility Review
Cross-document consistency, contradiction analysis and defensibility.
Forensic Review & Advanced Evidence-Chain Preparation
Link-by-link evidence-chain examination for high-exposure files.
The mission level reflects the depth of the methodological review, not a purchased outcome.
CBAM documentary and evidentiary review
CBAM is WEETRA's first operational use case. WEETRA reviews the coherence and traceability of supporting information relating to goods, installations, embedded emissions, calculation inputs and documentary evidence.
Eight statuses.
The only form a conclusion takes.
These are internal methodological review statuses and not regulatory decisions or certifications.
Preserve the evidence. Preserve how it was reviewed.
WEETRA documents the evidentiary process behind a regulatory determination: the materials reviewed, the facts extracted, the contradictions identified, the limitations recorded, the remediation carried out and the human decision ultimately issued.
Each covered file is linked to a traceable evidentiary record. Depending on the review level, the resulting Determination Package may include versioned registers, an Evidence Manifest and SHA-256 reference hashes supporting future integrity verification.
The result is not simply a report. It is a structured record of how the determination was reached, and of the documentary state it relied on.
Integrity verification confirms correspondence with a recorded reference file. It does not establish the truth or regulatory validity of its content.
