Audit Analysis

The CTR São Gonçalo landfill gas project has VVB-confirmed additionality and a measured baseline, but is undermined by the absence of a buffer pool, unaddressed reversal risk, a 0% leakage deduction with inconsistent justification across documents, and four corrective action requests. Multiple contradictions between the PDD, monitoring report, and verification report—particularly on the grid emission factor and leakage treatment—reduce confidence in the robustness of the credit claims.

Red Flags

  • No buffer pool percentage stated and reversal events explicitly 'not addressed' in the verification report, leaving permanence risk unmitigated for a landfill gas project
  • Leakage deduction of 0% with justification described as 'not addressed' in the verification report, contradicting the PDD's claim of 'deemed negligible'
  • Grid emission factor differs by a factor of ~2.7 between the monitoring report (0.3263) and the PDD (0.122), with no reconciliation provided
  • Four Corrective Action Requests issued during verification, including a calibration delay requiring a +0.3% conservative correction to project emissions
  • FPIC status contradicted: validation report confirms FPIC conducted, while the PDD records it as not conducted
