Certificación de Reducción de Emisiones de GEI de Aceites Manuelita S.A.

Audit Analysis
A Colombian palm-oil biogas project with VVB-verified additionality and a measured baseline, but undermined by extensive data-quality findings (GWP errors, missing calibration, traceability gaps), a 0% leakage deduction deemed negligible without robust justification, and no buffer pool. Multiple contradictions across documents—including a unit-level discrepancy in reported ERR and a 2.3× difference in grid emission factors—reduce confidence in the reported figures.
Red Flags
- Extensive material findings: GWP value for CH4 incorrectly set at 25 instead of 28, missing calibration certificates across multiple processes, and biogas flow traceability could not be verified in several years
- 0% leakage deduction deemed negligible for a multi-process biogas/waste project with no quantified leakage analysis in the extracted record
- Grid emission factor discrepancy: 0.564 tCO2e/kWh (monitoring report, 2020 data) vs 1.3 tCO2e/kWh (PDD, 2023) — a 2.3× difference that materially affects the baseline
- Low extraction confidence across the document set, meaning key figures may be misread or incomplete
