GS1247 VPA 177 Zoba Debub Community Boreholes

Audit Analysis

This Gold Standard borehole project in Eritrea has VVB-verified additionality and no reversal events, but is undermined by a significant baseline correction (water boiling test value changed from 0.3 kg to 0.8892 kg due to kerosene contamination), a leakage deduction that dropped from 5% in the PDD to 0% in the verification report, and a usage-rate discrepancy (90% cap in the PDD versus 95% in the verification report). Multiple open forward action requests and version-mismatch issues further erode confidence in the data integrity.

Project Description

Red Flags

• ⚠Baseline Water Boiling Test value corrected from 0.3 kg to 0.8892 kg after initial test was contaminated by kerosene use, materially altering the baseline emission factor
• ⚠Leakage deduction reduced from 5% in the PDD (2023) to 0% in the verification report (2024) with only a 'deemed negligible' justification, creating a direct contradiction between documents
• ⚠Usage rate reported as 95% in the verification report while the PDD and BAMG changes imposed a 90% cap, raising questions about which value was actually applied in the ER calculation
• ⚠Inconsistency in total ERs between the MR table (80,911 tCO2e) and the ER spreadsheet (79,172 tCO2e) flagged as CL#01 in the verification report
