Safe Water Programme – Nigeria - VPA 75
Score Breakdown
Integrity
verified Additionality was confirmed by Earthood Services Private Limited in the validation report using a combined test.
missing Leakage treatment is incomplete in the extracted record: the justification is described as quantified, but no deduction percentage is stated and buffer pool coverage is not found.
Transparency
verified The project has a named VVB and a defined recent monitoring period from 2024-12-01 to 2024-12-31.
missing The extracted record does not provide verified or claimed ERR totals, and the low extraction confidence suggests at least one key document was hard to read.
Claim Safety
verified The project uses the TPDDTEC methodology and reports a local-field FNRB value of 82.3, which is at least grounded in local data.
missing The project is marked CORSIA-eligible, while CCP status is not stated; combined with missing ERR totals and no leakage percentage, this leaves residual over-crediting and dual-claim risk.
Documentation
verified Twelve documents were used, including a validation report and stakeholder consultation material, and the crediting period is clearly stated.
missing Extraction confidence is low, and the record contains a contradiction on the usage monitoring method, with one document indicating annual survey and another indicating sampling.
Detailed Analysis
Integrity
The validation report dated 2022-05-20 names Earthood Services Private Limited and says additionality was confirmed through a combined test, with no material findings or corrective actions reported. On the weaker side, the extracted record does not state a buffer pool percentage, does not provide a leakage deduction percentage, and does not show verified emission reduction totals, so permanence and quantification confidence are only moderate.
Transparency
The file identifies the registry as Gold Standard, names the VVB, and gives a recent monitoring period from 2024-12-01 to 2024-12-31. But the extracted record does not include claimed or verified ERR totals, and the low extraction confidence indicates at least one source document was difficult to read, reducing transparency.
Claim Safety
The project’s use of TPDDTEC and a locally derived FNRB value of 82.3 are positive signs, and the validation report supports additionality. Still, the absence of verified ERR totals, the missing leakage percentage, and the fact that CORSIA eligibility is true while CCP status is not stated leave meaningful over-crediting and dual-claim concerns.
Documentation
Twelve documents were used, including a validation report, stakeholder consultation material, and an appendix, which supports a reasonably broad evidence base. However, the extraction confidence is low, and the record contains a contradiction on the usage monitoring method: one source says annual survey while another says sampling. The crediting period is stated, but several key quantitative fields remain unavailable in the extracted record.
Overall
This is a mid-tier file with some solid validation evidence but important gaps in quantification and monitoring detail. I privileged the more recent 2024 monitoring-period information for usage monitoring, but the contradiction with the earlier sampling reference lowers reliability. Because the record is incomplete and low-confidence, the score is held below a strong investment-grade level.
Audit Analysis
The project has some positive integrity signals: the VVB confirmed additionality, no material findings were reported, and the monitoring period is recent. However, key crediting details are missing or weakly evidenced, including the absence of verified error totals, no stated leakage deduction percentage, and no buffer pool information. Overall, this is a moderate-quality file with meaningful evidence gaps and some reliability concerns.
Project Description
Developer: Impact Carbon Type: Energy Efficiency - Domestic Size: Small Scale Crediting period: 2024-01-08 → 2029-01-07 Estimated annual credits: 60000 tCO2e SDGs: Goal 6: Clean Water and Sanitation, Goal 3: Good Health and Well-Being, Goal 13: Climate Action, Goal 8: Decent Work and Economic Growth, Goal 1: No Poverty, Goal 7: Affordable and Clean Energy
Red Flags
- No verified total emission reduction figures are available in the extracted record, limiting confidence in the claimed issuance.
- The monitoring method is contradictory across documents, and the record has low extraction confidence, which weakens trust in the documentation.

Cosa migliorerebbe questo punteggio
- Publish verified and claimed ERR totals for the monitoring period, with a clear reconciliation to issuance.
- State the leakage deduction percentage, buffer pool treatment, and resolve the monitoring-method contradiction with a single authoritative source.
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
