Score Breakdown

Integrity

verified Additionality was confirmed by the VVB in the validation report, and the baseline was reassessed in 2024.

missing Leakage treatment is weakly supported because the validation report records a 5% deduction while also saying leakage was not addressed, and reversal treatment is not clearly documented.

Transparency

verified The project has a named VVB, a defined monitoring period from 2023-01-01 to 2024-12-31, and quantified claimed versus verified ERs in the extracted record.

missing Low extraction confidence and unresolved contradictions reduce confidence in the completeness and consistency of the public documentation.

Claim Safety

verified The project is an avoidance activity under Gold Standard with a recent baseline reassessment, which is generally safer than a project-specific baseline with no updates.

missing The record shows a 5% leakage deduction but no clear justification, and the verified and claimed ER figures differ materially in the extracted data.

Documentation

verified A relatively large set of documents was used, and the validation report includes material findings and closed corrective actions.

missing At least one key document was poorly readable, the evidence list is not specific, and several core fields are contradicted across documents.

Detailed Analysis

Integrity

The validation report confirms additionality was verified by Earthood Services Limited, and the baseline was last reassessed in 2024, which supports the project’s core environmental case. Still, the report also records a 5% leakage deduction while saying leakage was not addressed, and reversal events are marked as not addressed, so permanence and leakage robustness are only moderate.

Transparency

The extracted record identifies the VVB, the monitoring period, and both claimed and verified ER totals, which helps traceability. But the documentation quality is weakened by low extraction confidence and by contradictions in several key fields, so the overall transparency is limited.

Claim Safety

As a Gold Standard avoidance project, the activity type is inherently less risky than many removal projects, and the baseline was reassessed in 2024. However, the leakage treatment is inconsistent, the usage rate and reversal information conflict across documents, and the verified versus claimed ER figures in the extracted record do not align cleanly, which raises over-crediting concerns.

Documentation

The validation report shows multiple closed clarification and corrective action items, and the project has a substantial document set with 35 documents used in extraction. Even so, the evidence list is not specific, the extraction confidence is low, and the record contains several unresolved contradictions, so documentation quality is only fair.

Overall

I privileged the 2025 validation report for fields it directly states because it is the most recent and authoritative document in the extracted set, but I discounted confidence where it conflicts with earlier records. The contradictions are material: leakage is described as both not addressed and negligible, usage rates differ, reversal status differs, and the crediting period conflicts with an earlier period, so reliability is reduced. Because documentation is weak and integrity is only moderate, the project should be treated as medium risk rather than high confidence.

Audit Analysis

This is a Gold Standard certified avoidance project with VVB-confirmed additionality and a recent baseline reassessment, which supports moderate integrity. However, several reliability issues remain: key leakage and reversal treatment is not clearly explained, the extraction confidence is low, and there are multiple contradictions across documents that weaken confidence in the claimed reductions.

Project Description

By rehabilitating and installing critical water infrastructure within communities and committing to ensure that it is maintained and tested for water quality over the project lifetime, the project reduces the risk of water borne illnesses and the need to boil water for purification, which exposes households to hazardous air pollution. This saves thousands of tonnes of firewood per year and reduces CO2 emissions. By implementing a WASH campaign and training, the project also improves hygiene and sanitation practices within the communities. As the burden for collecting water and firewood for purification falls disproportionately on women and children, by installing and rehabilitating boreholes, the project reduces the time poverty of women and children and allows them to spend the time saved on other activities. Provision of safe clean water, especially in rural areas Positively impacts thousands of people in the project area, especially women and children Reduction of firewood Reduced time spent on collecting wood and water Reduction in the risk of waterborne illness More project information is available in the Gold Standard Impact Registry .

Red Flags

  • Leakage is deducted at 5% but the justification is recorded as not addressed in the extracted validation report.
  • The record contains several contradictions, including different values for leakage treatment, usage rates, reversal status, and the crediting period.

Cosa migliorerebbe questo punteggio

  • Provide a clean, reconciled document trail explaining the leakage deduction, reversal treatment, and the final crediting period.
  • Publish a clearer monitoring package with consistent usage-rate assumptions, verified values, and a specific evidence list tied to each claim.

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