Eficiencia energética por Control Operacional en la Refinería de Cartagena

Audit Analysis

An energy-efficiency project at the Cartagena Refinery verified under the Colombian CerCarbono registry using AMS-II.D methodology. The VVB confirmed additionality via a combined test and the project delivered 131% of the pro-rata ex-ante expectation for the elapsed monitoring period, but significant MRV errors (a 21.92% baseline underestimation and inclusion of non-eligible combustion-efficiency improvements) were identified and corrected during verification. Safeguards documentation is weak, with no FPIC, no grievance mechanism per the verification report, and permanence/reversal risk left unaddressed.

Project Description

Red Flags

• ⚠Material finding: 21.92% underestimation of emission reductions for Unit U-044 due to a reference error in the 2021 baseline, corrected in the monitoring report
• ⚠Material finding: combustion-efficiency improvements were incorrectly included in emission reduction calculations, which is not acceptable under AMS-II.D; corrected to exclude non-eligible activities
• ⚠Permanence and reversal risk explicitly not addressed (Section 5.2.3 states it does not apply to the PMCC) and no buffer pool is documented
• ⚠Grid emission factor contradiction within the same monitoring report: 0.3316 vs 0.0582 tCO2/kWh, a factor-of-5.7 discrepancy
• ⚠No FPIC conducted and no grievance mechanism per the verification report, despite the PDD claiming otherwise
