GHG Emissions Reduction through Modjo Common Effluent Treatment Plant

Audit Analysis

This CDM methane-avoidance project in Ethiopia has a VVB-confirmed additionality assessment but is undermined by 23 material findings and an equal number of corrective actions identified in the validation report, including the absence of a documented investment analysis and multiple undemonstrated applicability conditions. No verified monitoring data, buffer pool, or reversal-event record is available, and five contradictions between the PDD and validation report—including a tenfold discrepancy in the claimed ERR—raise serious data-reliability concerns. The project's documentation is further weakened by low extraction confidence and the absence of any monitoring or verification reports in the extracted record.

Project Description

Red Flags

• ⚠23 material findings in the validation report, including the mandatory investment analysis step not being documented in the PDD and multiple applicability conditions (biogas usage, lagoon depth/residence time, W11 and E2 alternatives) not demonstrated
• ⚠Tenfold discrepancy in total ERR between the PDD (1,426,020) and the validation report (142,602), likely a typographical error but unexplained in the record
• ⚠No verified monitoring data, buffer pool, or reversal-event record found in any available document
• ⚠Five contradictions between the PDD and validation report across leakage justification, energy source, additionality test type, ERR figure, and crediting period
• ⚠Grid emission factor dated 2007 with no evidence of update or reassessment during the 2019–2028 crediting period
