Gongba River Small Hydropower Project in Gansu Province

Audit Analysis

A small hydro CDM project in Gansu, China, with VVB-confirmed additionality and a reasonable negligible-leakage claim, but undermined by a seven-fold discrepancy in claimed emissions reductions between the PDD and the validation report, a contradictory baseline-method description, eight unresolved material findings, and a near-total absence of monitoring or verified-emissions data. The low extraction confidence and missing key records further limit confidence in the project's reported performance.

Project Description

Red Flags

• ⚠ERR contradiction: the validation report states 56,840 tCO₂ while the PDD states 397,880 tCO₂ for the same crediting period — a 7× discrepancy that cannot be reconciled from available documents
• ⚠Baseline method is described as 'project' in the validation report but 'jurisdictional' in the PDD, creating ambiguity about the actual baseline construction
• ⚠Eight material findings (CARs and CLs) were raised by the VVB, including missing IRR parameters, undefined plant load factor, and non-compliant emission-factor calculations
• ⚠No monitoring-period data, verified ERR figures, or usage-monitoring method found in any available document
• ⚠Minimum extraction confidence is rated low, indicating at least one key document was poorly readable
