"Forced Methane extraction from Organic wastewater", at Mandya District, Karnataka by M/s Sri Chamundeswari Sugars Ltd.

Audit Analysis

A CDM biogas capture project at a sugar factory in Karnataka with VVB-confirmed additionality and a recognised methodology (AMS.III.H v4), but undermined by a ten-fold discrepancy in claimed emission reductions between the PDD and validation report, an initially unclear baseline power source, a fixed 2004 grid emission factor applied across the full crediting period, and a thin 0% leakage justification. Multiple corrective actions were required at validation, and the verified ERR for the 2011–2012 monitoring period was not found in the extracted record.

Project Description

Red Flags

• ⚠Ten-fold discrepancy in total ERR between the PDD (344,240 tCO2e, Jan 2007) and the validation report (34,424 tCO2e, Apr 2007) — a data-reliability concern that cannot be fully resolved without the original calculation sheets
• ⚠Baseline power source (grid vs diesel) was initially unclear in the PDD and required a corrective action; the grid emission factor of 0.86 tCO2e/MWh was fixed ex ante from 2004 data for the entire 10-year crediting period, risking over-crediting as India's grid decarbonises
• ⚠Verified ERR for the 2011–2012 monitoring period is not present in the extracted record, preventing any pro-rata delivery check
