Audit Analysis
A CDM coal mine methane utilization project with a solid VVB-confirmed investment additionality test and legally mandated capture, but undermined by a project-specific modeled baseline, contradictory leakage justifications across documents, and a significant under-delivery of roughly 37% of the pro-rata ex-ante expectation for the monitored period. The absence of FNRB, usage-rate, and buffer-pool data limits confidence in the credit quantity.
Red Flags
- Verified emissions reductions (179,526 tCO2) represent only ~37% of the pro-rata ex-ante expectation (~480,000 tCO2) for the 14-month monitoring period, suggesting the PDD baseline may have been overly optimistic
- Leakage justification is contradictory: the validation report (2011) states 'deemed negligible' while the monitoring report (2014) states 'quantified', yet both apply a 0% deduction
- FNRB value, usage monitoring method, and usage rate are all absent from the extracted record, leaving the energy-replacement assumption unverifiable
- Grid emission factor is from 2007 and has not been updated in the available documents
- Gas capture legally mandated — additionality in doubt
