GS1247 VPA 55 Eritrean District Boreholes

Audit Analysis

This Gold Standard borehole rehabilitation project in Eritrea has VVB-verified additionality and no reversal events, but is undermined by 12 cross-document contradictions, a potential double-counting of boreholes flagged in material findings, a leakage deduction that was reduced from 5% to 0% without clear justification, and a 16% gap between claimed and verified emission reductions. The low extraction confidence and numerous open corrective actions further erode confidence in the data integrity.

Project Description

Red Flags

• ⚠Material finding CL#1 identifies potential double counting of boreholes ZMA 054/055 and ZMA 056/057 due to identical GPS coordinates, which could inflate emission reductions
• ⚠Leakage deduction was reduced from 5% in the PDD to 0% in the 2023 monitoring report, with the justification shifting from 'quantified' to 'deemed negligible' — a weakening of conservatism without documented re-analysis
• ⚠12 contradictions across documents, including conflicting FNRB values (0.97 national default vs 0.85 local field), conflicting FPIC status (false in monitoring report vs true in validation report), and conflicting crediting periods (2015–2022 vs 2025–2030)
• ⚠Total ERR claimed (39,367 tCO2) exceeds total ERR verified (33,064 tCO2) by approximately 16%, and no lifetime ex-ante estimate is available to contextualise the figures
• ⚠Low extraction confidence across the document set, with one document of unknown type, reducing reliability of the extracted data
