Aguan biogas recovery from Palm Oil Mill Effluent (POME) ponds and biogas utilisation - Exportadora del Atlántico, Aguan/Honduras

Audit Analysis

The Aguan POME biogas project has a solid additionality foundation (VVB-confirmed investment test by TÜV SÜD) and resolved validation findings, but is undermined by a severe seven-fold discrepancy in claimed emissions reductions between the validation report and an appendix, a contradiction in baseline methodology, and a near-total absence of monitoring or verification data. The low extraction confidence and missing key parameters (buffer pool, FN-RB, usage rates, verified ERR) leave substantial uncertainty about the project's actual credit volume and integrity.

Project Description

Red Flags

• ⚠Seven-fold discrepancy in total claimed ERR: 30,183 tCO₂e in the validation report versus 211,284 tCO₂e in an appendix — a factor-of-7 gap that cannot be reconciled without further documentation
• ⚠Baseline method contradicted across documents: the validation report describes a project-specific baseline while an appendix references a jurisdictional baseline, fundamentally altering the credit calculation
• ⚠No monitoring period, verified ERR, or usage monitoring method found in any available document — the project's actual performance is entirely unverified
• ⚠Leakage treatment contradicted: the validation report states leakage was 'deemed negligible' (0% deduction) while an appendix indicates it was 'quantified', creating ambiguity about whether a real deduction was applied
• ⚠Low extraction confidence across the document set, meaning at least one key document was poorly readable and critical data may be missing
