Biogas and biomass based co-generation project at CDBL

Audit Analysis

A CDM biogas co-generation project in India with VVB-confirmed additionality and no over-crediting (81% of pro-rata expectation delivered), but undermined by a baseline-method contradiction between the PDD and the monitoring report, a 0% leakage deduction with inconsistent justification across documents, and the absence of any buffer pool or safeguards documentation. The project is functional but carries moderate data-reliability risk.

Project Description

Red Flags

• ⚠Baseline method is stated as 'jurisdictional' in the 2008 PDD but 'project' in the 2022 monitoring report — a fundamental definitional contradiction that undermines baseline credibility
• ⚠Leakage justification shifts from 'deemed negligible' (2011 monitoring report) to 'quantified' (2022 monitoring report) while the deduction remains 0%, creating an internal inconsistency
• ⚠No buffer pool percentage, no reversal-event data, and no FPIC or grievance-mechanism documentation found in any available record
• ⚠Grid emission factor of 0.793 tCO2e/MWh is anchored to 2006 data; no updated or reassessed value is documented
