Biogas project, BAJ Unit 6

Audit Analysis

This CDM biogas project in Indonesia uses a standardized methodology (AMS-III.H / AMS-I.F) and passed validation by JQA with only minor clarifications, but the available record is limited to the validation report and PDD with no monitoring or verification data. The project-specific modeled baseline, absence of a buffer pool, and a 0% leakage deduction justified only as 'deemed negligible' leave meaningful gaps in permanence and leakage treatment. A significant discrepancy in claimed ERR figures (41,860 vs 293,020 tCO₂e) across documents further undermines confidence in the credit volume.

Project Description

Red Flags

• ⚠ERR contradiction: the validation report (2016-10-28) states 41,860 tCO₂e while an unidentified document references 293,020 tCO₂e — a 7× discrepancy that cannot be reconciled from available records
• ⚠No buffer pool or permanence mechanism is stated in any available document for a project whose crediting period ended in September 2023
• ⚠Leakage deduction of 0% is justified solely as 'deemed negligible' in the PDD, with no quantified assessment for a biogas project where uncontrolled methane release is a realistic risk
• ⚠No monitoring report, verification report, or verified ERR figure is present in the extracted record, making it impossible to confirm actual delivery against the claimed 41,860 tCO₂e
