BRASCARBON Methane Recovery Project BCA-BRA-13
#16of 104 in Brazil#47of 213 in CDM (UNFCCC)#8of 62 in AMS-III.D
Audit Analysis
A CDM anaerobic manure digestion project (AMS-III.D v21) with a VVB-confirmed investment additionality test and a project-specific modeled baseline. The main weaknesses are a 0% leakage deduction whose justification is contradictory across documents, the absence of a stated buffer pool or reversal-risk treatment, and a missing verified ER figure for the monitoring period. Nine minor administrative findings (form errors, table-sum mistakes, monitoring-frequency inconsistencies) were noted but no corrective actions were required.
Red Flags
- Leakage deduction is 0% and the monitoring report (2021) states leakage was 'not addressed', while the validation report (2020) claims it was 'quantified' — an unresolved contradiction that undermines confidence in the leakage treatment.
- No buffer pool percentage or reversal-event history is stated in any available document, leaving permanence risk unquantified for a methane-avoidance project.
- The verified ER for the monitoring period (2019-06 to 2020-12) is not reported in the extracted record, preventing an independent cross-check of the claimed 79,555 tCO₂e.
