Emission reductions through partial substitution of fossil fuel with alternative fuels in the 2 cement plants of PT Holcim Indonesia Tbk

Audit Analysis

A CDM biomass fuel-substitution project at two Indonesian cement plants with VVB-confirmed additionality and an established methodology (ACM0003 v04), but hampered by a project-specific baseline, a lack of verified ERR figures, and several material findings around AFGHG calculation transparency and fuel availability that required corrective action. The grid emission factor discrepancy between the PDD and monitoring report, combined with missing monitoring parameters, limits confidence in the claimed credit volume.

Project Description

Red Flags

• ⚠AFGHG calculation lacked transparency regarding emission factors for alternative fuels, flagged as a material finding in the verification process
• ⚠Grid emission factor differs between the PDD (0.754, 2008) and the monitoring report (0.891, 2011), with no documented explanation for the change
• ⚠No verified ERR figure is available in the extracted record, preventing an independent check of the 125,771 tCO₂e claimed
• ⚠Leakage is described as 'quantified' but the actual deduction percentage is not stated in any available document
• ⚠Crediting period start date differs between the validation report (2008-04-01) and the monitoring report (2008-09-02)
