Audit Analysis
Nordgau Carbon is a German industrial biochar removal project verified by bio.inspecta AG under the Puro methodology. Additionality is well-supported by a VVB-confirmed investment test, and no material findings or corrective actions were reported. However, the project carries notable gaps: a 1000-year permanence claim with no stated buffer pool, leakage explicitly not addressed, and a significant discrepancy between the verified ERR (692 tCO₂ in the verification report) and the issued ERR (2,759 tCO₂ in the issuance document) that raises over-crediting concerns.
Red Flags
- ERR discrepancy: the verification report (2023-12-21) states 692 tCO₂ while the issuance document (2024-01-10) states 2,759 tCO₂ — a roughly 4× difference with no documented explanation in the extracted record
- Leakage explicitly noted as 'not addressed' with no deduction percentage or justification provided
- Usage rate (assumed and verified) not stated in any document, limiting ability to assess end-use claims
