GGP Biogas Project

Audit Analysis

The GGP Biogas Project in Indonesia is a CDM methane-avoidance project with VVB-confirmed additionality and detailed monitoring equipment, but it is undermined by 19 material findings, 25 corrective actions, a 39% under-delivery relative to the PDD estimate, and a project-specific baseline with a thin leakage justification. The volume of unresolved issues at verification raises serious concerns about whether the project operated as designed and whether the claimed reductions are robust.

Project Description

Red Flags

• ⚠19 material findings and 25 corrective actions identified in the verification report, including flow meter accuracy below required class, uncalibrated V-Notch weir, and only one of two planned boilers retrofitted with a biogas burner
• ⚠Verified ERR of 2,585 tCO2e represents only ~4% of the pro-rata PDD expectation (~65,300 tCO2e for the 4-year monitoring window), a 39.22% shortfall flagged in the record
• ⚠Contradiction between the verification report (2,585 tCO2e) and the PDD (40,813 tCO2e) for total ERR claimed, with no reconciliation documented
• ⚠Leakage deduction of 0% justified only as 'deemed negligible' with no quantified analysis for a biogas/digestion project where fugitive methane is a known risk
• ⚠No buffer pool, no reversal-event tracking, and no permanence mechanism documented under the CDM framework
