Audit Analysis
The Dachunhe 50 MW run-of-river hydro project in Yunnan is a straightforward CDM avoidance project displacing grid electricity, with a jurisdictional baseline and a reasonable 0% leakage deduction. However, the extracted record lacks key additionality test details, monitoring period data, and several MRV parameters, and a crediting-period discrepancy between documents introduces a data-reliability concern. The project was validated and registered with no corrective actions required, but the evidence base in the available documents is incomplete.
Red Flags
- Additionality test type and VVB confirmation are not stated in the extracted record, leaving the core CDM additionality requirement unverified in the available data
- Crediting period contradicts between the validation report (7 years, 2016–2023) and an earlier undated document (14 years, 2009–2023), creating ambiguity about the project's actual crediting window
- Monitoring period is not stated in any available document, making it impossible to confirm whether the verified ERR covers a full or partial crediting period
- Buffer pool percentage is not stated; while hydro carries low reversal risk, the absence of any permanence safeguard documentation is a gap
