Guizhou Yingxing CMM Power Generation Project

Audit Analysis

A coal mine methane power generation project in China with VVB-verified additionality and legally mandated capture, delivering slightly above its pro-rata expectation in the first monitoring period. Key gaps include the absence of a stated buffer pool, unaddressed reversal risk, and a project-specific (rather than jurisdictional) baseline. The verification process was thorough, with nine corrective action requests raised and closed, but several operational parameters remain unstated in the available record.

Project Description

Red Flags

• ⚠No buffer pool percentage is stated in any available document, leaving permanence risk unquantified for a project where facility shutdown would resume methane emissions
• ⚠Reversal events are explicitly noted as 'not addressed' in the extracted record, despite the inherent risk that cessation of CMM capture would release methane back to the atmosphere
• ⚠Four contradictions exist across documents, including a discrepancy in the baseline characterization (measured vs. modeled) and the additionality test type (investment vs. combined), suggesting internal inconsistency in project documentation
• ⚠Gas capture legally mandated — additionality in doubt
