Gansu Huanghe Bingling Hydropower Station Project

Audit Analysis

A registered VCS hydropower project (ACM0002) with VVB-confirmed additionality and a jurisdictional baseline, but the record is marred by multiple cross-document contradictions on baseline method, leakage justification, and claimed ERR figures. A material finding in the verification report flags a 47.4% under-delivery relative to the PDD estimate for the 2009 period and incomplete metering documentation, while one corrective action on monitoring details remains open. The project's inherent low permanence risk as a hydropower asset is partially offset by the absence of any stated buffer pool.

Project Description

Red Flags

• ⚠Material finding: actual emission reductions of 142,109 tCO2e in the 2009 period were 47.4% below the PDD estimate of 270,139.1 tCO2e, indicating the ex-ante model was significantly miscalibrated.
• ⚠Contradiction on baseline method: the 2009 monitoring report describes a project-specific baseline while the 2025 monitoring report describes a jurisdictional baseline — a fundamental methodological shift that is not explained in the available documents.
• ⚠Contradiction on leakage justification: one monitoring report states leakage was quantified while the 2025 monitoring report states it was deemed negligible with a 0% deduction, and no quantified leakage figure appears in the extracted record.
• ⚠One corrective action (complete details on monitoring meters and multiplication factors) remains open in the verification report.
