Cerro Patacón Landfill Gas Utilization Project

Audit Analysis

The Cerro Patacón Landfill Gas Utilization Project (CDM-8962, Panama) has a VVB-verified combined additionality test and no material findings, but suffers from a 0% leakage deduction with inconsistent justification across documents, a project-specific modeled baseline with no stated reassessment, and a complete absence of monitoring data. The ERR figures in the PDD and validation report differ by a factor of seven, which is explainable as an annual-versus-lifetime reporting basis difference but creates interpretive risk. Overall, the project shows moderate design quality but very limited verifiable performance evidence.

Project Description

Red Flags

• ⚠Leakage deduction of 0% with the validation report stating the issue was 'not addressed' while the PDD claims it was 'deemed negligible' — the VVB did not confirm the developer's justification
• ⚠No monitoring report or verified ERR figure is available in the extracted record, making it impossible to confirm actual credit delivery against the ex-ante estimate
• ⚠No buffer pool or permanence mechanism is documented for the project, and no reversal events data is available
• ⚠Baseline is project-specific and modeled, with no stated date of last reassessment
