Audit Analysis

A CDM swine-waste methane avoidance project in Brazil with VVB-confirmed additionality (combined test by TÜV SÜD), but undermined by a ten-fold discrepancy in claimed emissions reductions between the PDD and the validation report, five material findings including farm exclusions and baseline inconsistencies, and a near-total absence of monitoring data. The project's integrity is further weakened by the lack of any documented permanence mechanism, a thin leakage justification, and low extraction confidence across the available documents.

Red Flags

  • Ten-fold discrepancy in total ERR: the PDD states 219,390 tCO₂e while the validation report states 21,939 tCO₂e — a factor-of-10 error that undermines confidence in the project's quantification
  • Five material findings in the validation report, including exclusion of two farms (Brandalize for environmental-license non-compliance, Pasqual for lack of head-count traceability) and baseline-emission inconsistencies between the PDD and other documents
  • Low extraction confidence across the document set, indicating at least one key document was poorly readable
