Score Breakdown

Integrity

verified Additionality was confirmed by TÜV NORD CERT GmbH using a barrier test, which supports the project’s core eligibility case.

missing Leakage treatment is not fully transparent because the deduction percentage is not stated, and the verification report lists multiple corrective actions.

Transparency

verified The project has a named VVB, a defined monitoring period in 2024, and a recent baseline reassessment in 2024.

missing The record shows contradictory emissions figures and inconsistent usage-monitoring descriptions across documents, reducing reporting clarity.

Claim Safety

verified The project is Gold Standard certified and the verified emissions reductions are lower than the claimed amount, which suggests some conservatism in the final issuance.

missing The baseline is project-specific rather than jurisdictional, leakage is not fully quantified in the extracted record, and CORSIA eligibility is not stated.

Documentation

verified The evidence set is broad, with 38 documents used and multiple official document types represented.

missing Extraction confidence is only medium, and the verification report lists several corrective actions, including incomplete PDD updates and blank QA/QC fields.

Detailed Analysis

Integrity

The project’s additionality is reasonably supported because the verification report names TÜV NORD CERT GmbH and says a barrier test was used. Baseline validity is moderate: the baseline was reassessed in 2024, but it remains project-specific rather than a standardized jurisdictional baseline. Permanence is less relevant for an avoidance project, but reversal risk is not explicitly addressed and no buffer pool percentage is stated. Leakage is described as quantified, yet the actual deduction percentage is missing from the extracted record, which weakens confidence.

Transparency

Transparency is helped by the presence of a named VVB, a defined 2024 monitoring period, and a recent baseline reassessment. However, the record contains contradictory usage-rate and emissions figures across documents, and the monitoring approach is not consistently described. The absence of a stated leakage deduction percentage and the lack of a clear CORSIA status also limit public clarity.

Claim Safety

Claim safety is moderate because the project is Gold Standard certified and the verified emissions reductions are below the amount claimed, which reduces the risk of over-issuance. That said, the baseline is project-specific, leakage is not fully quantified in the extracted record, and CORSIA eligibility is not stated. The contradictions in usage rate, FNRB value, and emissions totals create additional uncertainty about the robustness of the claim.

Documentation

Documentation breadth is fairly strong, with 38 documents used and multiple official sources including validation, verification, monitoring, PDD, and appendix materials. Still, extraction confidence is only medium, and the verification report lists several corrective actions, including incomplete appendix updates and blank QA/QC fields. The record also shows that some key values differ across documents, which suggests the documentation package is not fully clean or internally consistent.

Overall

I privileged the more recent and more specific figures where possible, especially the 2024 monitoring-period information and the verification report’s VVB-confirmed additionality, because those are closer to the issuance context. However, the contradictions are material: usage rate, leakage justification, FNRB value, emissions totals, and crediting-period dates all differ across documents, so I reduced confidence and scores accordingly. The project looks viable but not especially robust on claim safety or documentation quality, and the missing leakage percentage plus unresolved corrective actions keep it in the mid-range rather than high-confidence territory.

Audit Analysis

This is a certified Gold Standard water project with VVB-confirmed additionality, a recent baseline reassessment, and strong safeguards on paper. However, the record shows several material inconsistencies across documents, missing leakage quantification, and a large gap between claimed and verified emissions reductions, which weakens confidence in the crediting claims.

Project Description

In Cambodia, untreated water and poor sanitation cause an estimated 10 million cases of diarrhea and 10,000 deaths each year, mostly in children living in rural areas. To date, social enterprise Hydrologic has reached nearly two million Cambodians with its ceramic water purifiers. With a filter in their homes, families can drink safely. By no longer needing to boil water, indoor air pollution from wood burning is reduced, household fuel costs are slashed, time is saved for women and children, and Cambodia’s vulnerable forests are protected. The project creates rural employment opportunities in filter manufacturing and distribution.   Women make up 47% of Hydrologic’s staff , including 60% of top-level managers and 60% of the rural sales force. Hydrologic also works with a microfinance institution to sell filters on credit, making them affordable for more Cambodians. The sale of Gold Standard carbon credits enables Hydrologic to continue researching and developing purifier technology and to train local producers and distributors, thus scaling up its positive impact.

Red Flags

  • The claimed and verified emission reductions differ materially, and the record contains multiple contradictory figures across reports.
  • Leakage is described as quantified or negligible, but the actual deduction percentage is not stated in the extracted record.
  • Several corrective actions and completeness issues were raised in the verification process, including missing QA/QC details and incomplete appendix updates.

Cosa migliorerebbe questo punteggio

  • Publish a clean reconciliation table for all contradictory figures, especially usage rate, FNRB, emissions totals, and crediting-period dates, with a clear explanation of which document governs each value.
  • State the actual leakage deduction percentage and provide a complete, updated monitoring package with resolved corrective actions and fully filled QA/QC fields.

Questi suggerimenti indicano quali prove pubbliche aggiuntive potrebbero migliorare il livello di confidenza di questa valutazione. Non garantiscono un punteggio futuro più alto.
