Chongqing Youyang County Youchou Hydropower Station Project

Audit Analysis

A small CDM hydro project in Chongqing, China, with a jurisdictional baseline and a VVB-verified emission reduction figure of 178,912 tCO₂e over a 7-year crediting period. The project is undermined by a major discrepancy between the PDD's claimed 1,252,384 tCO₂e and the VVB-verified figure, contradictory leakage justifications across documents, and the absence of stated additionality test details in the extracted record. Overall, the project shows moderate integrity with notable documentation and claim-safety concerns.

Project Description

Red Flags

• ⚠Major ERR discrepancy: the PDD (2019-08-20) claims 1,252,384 tCO₂e while the validation report (2019-08-25) and monitoring report (2019-08-15) both state 178,912 tCO₂e — a roughly 7-fold difference that is not explained in the extracted record
• ⚠Leakage justification is contradictory: the monitoring report (2019-08-15) records leakage as 'not addressed' while the validation report (2019-08-25) states it was 'deemed negligible', with a 0% deduction applied in both cases
• ⚠Additionality test type and VVB confirmation are not stated in the extracted documents, leaving a gap in the core CDM additionality requirement
• ⚠PDD form version 10.1 was used instead of the required version 11.0, flagged as a material finding with a corrective action to update
