Cervecería Hondureña Methane Capture Project

Audit Analysis

The Cervecería Hondureña Methane Capture Project is a CDM-registered brewery wastewater biogas project with a combined additionality test and a project-specific modeled baseline. Key weaknesses include a 0% leakage deduction with contradictory justifications across documents, the absence of a buffer pool, and low extraction confidence in the available record. The project completed its 7-year crediting period (2010–2017) with 57,414 tCO₂e verified, but documentation gaps and the unresolved leakage question limit confidence in the credit quality.

Project Description

Red Flags

• ⚠Leakage deduction of 0% with contradictory justifications: the PDD (2011) states leakage was 'deemed negligible' while the validation report (2012) records it as 'not addressed' — the VVB did not independently confirm the negligible-leakage claim
• ⚠No buffer pool is recorded for the project, leaving no safety margin against potential reversal if the biogas capture system is decommissioned or underperforms
• ⚠Minimum extraction confidence is rated low, and one of the four source documents is listed as 'unknown', reducing reliability of the extracted record
• ⚠FPIC and grievance mechanism fields are not stated in any available document, despite safeguards being mentioned in general terms
