Chongqing Chengkou County Bashan Hydropower Station Project

Audit Analysis

A CDM small-hydro project with VVB-confirmed additionality and a jurisdictional baseline, but limited monitoring detail, a contradiction in the leakage treatment, and an exact match between claimed and verified ERR that raises questions about independent verification depth. The project is broadly sound for its type but lacks the granular MRV transparency expected of a high-quality credit.

Project Description

Red Flags

• ⚠Total ERR claimed and verified are identical (1,441,594 tCO₂e), suggesting the verification may have simply confirmed the ex-ante estimate rather than independently measuring output over the full 7-year period.
• ⚠Contradiction between documents on leakage treatment: the validation report (Aug 2019) states leakage was 'deemed negligible' while an earlier document (Aug 2019) references a 'quantified' approach — the basis for the 0% deduction is unclear.
• ⚠No FPIC or grievance mechanism documented despite safeguards being mentioned; benefit-sharing is described but the specific mechanism is not detailed in the extracted record.
• ⚠One of the four source documents is listed as 'unknown,' reducing confidence in the completeness of the evidence base.
