Audit Analysis
A coal-mine-methane power generation project in Henan, China, verified by TÜV NORD CERT under the established ACM0008 methodology. Additionality is VVB-confirmed via an investment test and capture is legally required, which are strong positives. However, a significant discrepancy between the PDD and monitoring report on the ERR figure, a project-specific (modeled) baseline, and several data gaps (buffer pool, CORSIA/CCP status) temper the overall assessment.
Red Flags
- ERR figure discrepancy: the PDD reports 91,322 tCO₂ while the monitoring report reports 1,288,859 tCO₂ for the same field, creating material uncertainty about the ex-ante estimate versus the verified period figure
- Baseline is project-specific and modeled rather than jurisdictional or measured, increasing sensitivity to assumption choices
- Five contradictions across documents (ERR, additionality test type, FPIC, leakage justification, baseline type) indicate data-reliability concerns
- Gas capture legally mandated — additionality in doubt
Credit Vintages
No issuances recorded on the registry.
