Dak Psi 3 and 4 Hydropower Project

Audit Analysis

The Dak Psi 3 and 4 Hydropower Project is a VCS-registered renewable energy project in Vietnam with VVB-confirmed additionality and no material findings, but it is undermined by seven cross-document contradictions (including baseline method, FPIC status, and benefit-sharing descriptions), four outstanding corrective actions, and a project-specific baseline that conflicts with a jurisdictional characterization in the monitoring report. The ERR figures are internally consistent in the most recent verification (324,209 tCO₂e claimed and verified), and the 0% leakage deduction is defensible for a grid-displacement hydropower project, yet the absence of CORSIA/CCP status, a missing crediting-period end date, and a 2009-vintage grid emission factor leave meaningful gaps in claim safety and transparency.

Project Description

Red Flags

• ⚠Seven contradictions across documents, including baseline method (project vs jurisdictional), FPIC status (true in 2024 verification vs false in 2013 monitoring), and benefit-sharing description (false in 2024 vs true in 2022), indicating inconsistent project reporting over time
• ⚠Four corrective actions (CAR 01–04) were raised in the verification process, signalling unresolved compliance or data-quality issues
• ⚠Crediting-period end date is not stated in the 2024 verification report, while the PDD lists a 7-year window (2011-07-01 to 2018-06-30); the start date also differs (2010-10-09 vs 2011-07-01)
• ⚠Grid emission factor is from 2009 (0.5764 tCO₂/kWh); no updated or jurisdictional-average factor is referenced in the extracted record
• ⚠CORSIA eligibility and CCP status are not stated in any available document, leaving dual-channel risk unassessed
