Hechuan Yanjing Coal Mine Methane Utilisation Project

Audit Analysis

A CDM coal mine methane utilisation project with VVB-confirmed additionality via an investment test, but significant data gaps including no monitoring reports, a 10-fold discrepancy in claimed ERR between the PDD and validation report, and contradictory statements on whether methane capture is legally mandated. The project's integrity is moderate: the baseline is project-specific and modeled, leakage is set at 0% (reasonable for CMM but inconsistently justified), and no permanence buffer is in place.

Project Description

Red Flags

• ⚠10-fold discrepancy in total claimed ERR: the PDD states 1,749,250 tCO2 while the validation report states 174,925 tCO2 — a factor-of-ten difference that undermines confidence in the credit volume
• ⚠Contradiction on legal requirement of methane capture: the PDD asserts capture is legally required (which would negate additionality), while the validation report states it is not — the VVB's position is privileged but the inconsistency is unresolved
• ⚠No monitoring reports or verified ERR figures are available in the extracted record, making it impossible to assess actual delivery against the claimed baseline
• ⚠Leakage justification is inconsistent: the PDD describes it as 'deemed negligible' while the validation report states it was 'quantified' to zero
