Audit Analysis
A CDM landfill gas project in Brazil with a VVB-confirmed combined additionality test and no material findings, but significant data gaps including no monitoring or verification reports, a 7-fold discrepancy in claimed emission reductions between the PDD and validation report, and contradictory leakage treatment. The project has been operating since December 2021 yet only validation-stage documentation is available, limiting confidence in actual performance.
Red Flags
- Total ERR claimed differs by a factor of ~7 between the PDD (3,370,445 tCO2e) and the validation report (481,492 tCO2e), indicating the project proponent's initial estimate was far above the VVB-verified figure
- Grid emission factor contradicts between documents: 0.5985 in the PDD versus 0.3719 in the validation report, a 61% difference that materially affects credit volume
- Leakage treatment is contradictory: the PDD states leakage was quantified, while the validation report records it as not addressed, with a 0% deduction applied
- No monitoring report or verification report is available despite the project having been operational since December 2021
