BRASCARBON Methane Recovery Project BCA-BRA-14.
#9of 104 in Brazil#26of 213 in CDM (UNFCCC)#5of 62 in AMS-III.D
Audit Analysis
The BRASCARBON methane recovery project (CDM-5496) is a landfill gas avoidance project in Brazil using the standardized AMS-III.D methodology. Additionality is well-supported by a VVB-confirmed combined test, but the 0% leakage deduction is undermined by contradictory justifications across documents, and the project-specific modeled baseline adds uncertainty. The first monitoring period delivered roughly 77% of the pro-rata expectation, a moderate under-delivery that warrants watching in subsequent periods.
Red Flags
- Leakage justification is contradictory: the validation report (2020-09-10) states leakage was quantified, while the monitoring report (2021-02-01) records it as not addressed, yet the deduction is 0% in both cases
- Five material findings (CLs) and three corrective actions (CARs) were identified during validation, all corrected in PDD v10, indicating initial documentation quality was imperfect
- Total ERR verified figure is not stated in the extracted record, preventing independent cross-check of the 70,231 tCO2e claimed in the monitoring report
