Audit Analysis
The CTR Candeias Landfill Gas Project (CDM-3958) is a methodology-compliant LFG capture project with VVB-confirmed additionality, but suffers from an internal contradiction in claimed emission reductions, inconsistent leakage treatment across documents, and seven outstanding corrective actions. The project-specific modeled baseline and absence of stated permanence or safeguards detail limit confidence in the credit's robustness.
Red Flags
- Internal contradiction in the monitoring report: total ERR claimed appears as both 163,204 and 354,934 tCO2e in the same document (2021-02-03), undermining data reliability
- Leakage justification is inconsistent: the validation report (2020) states leakage is 'deemed negligible' while the monitoring report (2021) records it as 'not addressed', despite the methodology stating leakage is not applicable
- Seven corrective actions remain outstanding, including updating the PDD for national policies, correcting emission factor data vintage, and providing evidence for the SPECflare parameter
