Yangquan Guzhuang 8MW CMM Power Generation Project

Audit Analysis

The Yangquan Guzhuang 8MW CMM power generation project has VVB-verified additionality and established safeguards, but is undermined by five material findings (including a non-compliant TDLi,y parameter and incomplete IRR calculations), a 37% discrepancy in lifetime ERR between the PDD and validation report, a 0% leakage deduction with only a 'deemed negligible' justification, and the absence of a buffer pool or monitoring data. The low extraction confidence and missing monitoring report further limit confidence in the project's data integrity.

Project Description

Red Flags

• ⚠Five material findings in the validation report, including a TDLi,y parameter (3%) that does not comply with TOOL 05 requirements, raising over-crediting risk in project emission calculations
• ⚠Lifetime ERR differs by 37% between the PDD (1,748,817 tCO2e) and the validation report (2,403,370 tCO2e), with no clear reconciliation provided
• ⚠Leakage deduction of 0% justified only as 'deemed negligible' without quantification, in a CMM project where displaced methane or grid interactions could generate leakage
• ⚠Contradiction on whether CMM capture is legally required (earlier PDD: yes; later PDD: no), which directly affects additionality if capture is mandated
