Audit Analysis
A CDM biogas capture project (AMS-III.D) with a solid VVB-verified additionality assessment and no serious material findings, but weakened by a project-specific modeled baseline, inconsistent leakage justifications across documents, and first-period ERR delivery at roughly 64% of the pro-rata expectation. Several key monitoring parameters (fnrb method, usage monitoring, CORSIA/CCP status) are absent from the extracted record, limiting full verification.
Red Flags
- Leakage justification is inconsistent: the validation report (2010) states 'deemed negligible' while the monitoring report (2011) states 'quantified', yet both documents apply a 0% deduction — the basis for the zero deduction is not clearly documented
- First monitoring period ERR (11,050 tCO2e) is only ~64% of the pro-rata expectation derived from the ex-ante estimate (121,210 tCO2e over 7 years), suggesting the baseline or activity assumptions may be optimistic
- Crediting period start date differs between the validation report (2010-05-01) and the monitoring report (2010-08-28), creating ambiguity about the exact baseline reference period
