GS1247 VPA 121 Zoba Debub Community Boreholes
Score Breakdown
Integrity
verified Additionality was confirmed by Earthood Services Limited using a financial test.
missing Leakage treatment is weak: the record shows a 0% deduction but no justification is addressed, and the contradiction log shows an earlier 5% deduction.
Transparency
verified The monitoring period is clearly stated as 2023-01-01 to 2024-12-31, and the VVB is named.
missing Total ER claimed and total ER verified are not found in the extracted record, and extraction confidence is low.
Claim Safety
verified The baseline was reassessed in 2024, which is relatively recent.
missing FNRB is listed as 97 against a prior value of 85, and the contradiction log also shows conflicting usage rates and leakage treatment.
Documentation
verified The record includes many extracted fields, material findings, and corrective actions, showing broad document coverage.
missing Min extraction confidence is low, and the contradiction log shows a major crediting-period mismatch between 2025-05-01 to 2030-04-30 and 2013-05-01 to 2020-04-30.
Detailed Analysis
Integrity
The verification report names Earthood Services Limited and confirms additionality through a financial test, which supports the project’s core claim. Baseline method is project-based and the baseline was last reassessed in 2024, but leakage is not properly justified even though a 0% deduction is shown. Reversal risk is not clearly addressed beyond a statement that no extreme event occurred, and there is no buffer pool information in the extracted record.
Transparency
The monitoring period is clearly stated, and the record identifies the VVB and includes a substantial list of findings and corrective actions. However, total ER claimed and total ER verified are not found in the extracted record, and min extraction confidence is low, which reduces confidence in the completeness of the documentation. The usage monitoring method is annual survey, but the contradiction log shows earlier references to self-reporting, which weakens transparency.
Claim Safety
Claim safety is weakened by the combination of a project-specific baseline, unresolved leakage justification, and conflicting values in the contradiction log. The FNRB value of 97 is higher than the earlier 85 reference, and the record also shows conflicting usage rates and leakage deductions, suggesting possible over-crediting risk. The project is not shown to be CCP-approved or CORSIA-eligible in the extracted record, but the absence of those fields still leaves some uncertainty.
Documentation
The record is fairly rich in extracted fields, with many material findings and corrective actions listed, and it also notes FPIC and a grievance mechanism. Even so, min extraction confidence is low, and several key items are either not found or not stated, including buffer pool coverage and verified emission totals. The contradiction log also indicates a major mismatch in the crediting period, which is a serious documentation reliability issue.
Overall
I privileged the more recent validation report for items like leakage being not addressed, the 0% leakage deduction, annual survey monitoring, and the 2025-05-01 to 2030-04-30 crediting period, because it is the latest document in the record. That said, the contradiction log shows earlier documents with different leakage, usage, FNRB, and crediting-period values, so I reduced scores to reflect reliability concerns and possible versioning issues. The project’s overall profile is mixed: some procedural safeguards are present, but the accounting and documentation trail is not robust enough for a high-confidence assessment.
Audit Analysis
The project has some positive signs, including VVB-confirmed additionality, FPIC, and a grievance mechanism. However, key safeguards and accounting details are weakly documented, leakage is not justified, and several contradictions reduce confidence in the record.
Project Description
Developer: CO2balance UK ltd Type: Energy Efficiency - Domestic Size: Micro scale Methodology: GS TPDDTEC v 1. Crediting period: 2017-05-05 → 2024-05-04 Estimated annual credits: 10000 tCO2e SDGs: Goal 13: Climate Action, Goal 3: Good Health and Well-Being, Goal 6: Clean Water and Sanitation, Goal 5: Gender Equality
Red Flags
- Leakage is set at 0% but the justification is not addressed in the available documents.
- The record contains multiple contradictions on leakage, usage monitoring, FNRB, and the crediting period, which weakens reliability.

Cosa migliorerebbe questo punteggio
- Provide a clear, document-backed leakage assessment explaining why the deduction is 0% and reconcile the conflicting earlier 5% value.
- Publish a complete, version-controlled monitoring and verification package with verified ER totals, buffer or reversal treatment, and a resolved crediting-period history.
Questi suggerimenti indicano quali prove pubbliche aggiuntive potrebbero migliorare il livello di confidenza di questa valutazione. Non garantiscono un punteggio futuro più alto.
Risk Indicators
VVB-confirmed financial test

0% deduction without clear justification
Project baseline, reassessed in 2024
FPIC and grievance mechanism present
CORSIA/CCP status not stated
