Dong Nai 4 Hydropower Project

Audit Analysis

The Dong Nai 4 Hydropower Project is a CDM-registered hydro project with VVB-confirmed additionality (investment test) and a reasonable leakage treatment, but is undermined by four inter-document contradictions (additionality type, ERR figures, baseline method, crediting period), material meter-accuracy findings requiring 13 corrective actions, and the absence of documented FPIC or grievance mechanisms. Verified emissions for the monitoring period ran at roughly 63% of the pro-rata expectation derived from the PDD's ex-ante estimate, indicating conservative delivery rather than over-crediting.

Project Description

Red Flags

• ⚠Four contradictions across documents on additionality type, ERR magnitude, baseline method, and crediting period dates reduce confidence in the data record
• ⚠Meter accuracy class 0.5s was below the required 0.2s during the monitoring period, necessitating conservative discount factors and a temporary monitoring system
• ⚠13 Corrective Action Requests were raised during verification, indicating significant initial non-conformities in the monitoring plan
