Biogas from Ethanol Wastewater for Electricity Generation

Audit Analysis
A CDM biogas project in Thailand using standardised AMS methodologies, with a combined additionality test and no reported reversal events. However, a 20-fold discrepancy in claimed emission reductions between two monitoring reports, a project-specific modeled baseline, and contradictory leakage justifications significantly undermine confidence in the credit quantity and baseline robustness.
Red Flags
- 20-fold discrepancy in total ERR claimed (340 vs 6,913 tCO2e) between two monitoring reports dated 10 days apart (2019-08-19 vs 2019-08-29), raising serious over-crediting or data-integrity concerns
- Leakage justification contradicts itself across documents: the validation report (2018) states leakage was 'deemed negligible' while the monitoring report (2019) states it was 'quantified', yet the deduction is 0% in both cases
- Monitoring period covers only 14 days (2018-07-10 to 2018-07-24), which is extremely short for a continuous biogas generation project and raises representativeness concerns
- Baseline validity assessment tool application was initially missing (CAR 02 in the validation report), indicating a procedural gap in the additionality/baseline assessment
