Sarkisla Biogas Power Plant

Audit Analysis

The Şarkısla Biogas Power Plant is a VCS-registered avoidance project in Turkey that displaces grid electricity with biogas-generated power. While additionality was confirmed by TÜV SÜD America via a regulatory test and safeguards (FPIC, grievance mechanism) are in place, the project carries significant quality concerns: the VVB reduced the project proponent's claimed emissions reductions by roughly 48% (from 146,754 to 76,364 tCO₂e), 13 corrective action requests were raised during verification, and the PDD contained multiple gaps including missing leakage justification and incomplete emission calculations.

Project Description

Red Flags

• ⚠The project proponent's monitoring report claimed 146,754 tCO₂e for the 2021–2023 period, but the VVB verified only 76,364 tCO₂e — a 48% over-claim that was caught during verification
• ⚠13 Corrective Action Requests, 2 Additional Documentation Requests, and 5 Clarification Requests were raised during verification, all indicating material gaps in the PDD and monitoring data
• ⚠Leakage was assigned a 0% deduction with a 'deemed negligible' justification, yet the PDD originally contained no leakage treatment at all (flagged as a CAR)
• ⚠The PDD lacked technical specifications for the biodigester, flaring system, and generating units, and emission reduction equations were missing from Section 4.4
