Score Breakdown

Integrity

verified Additionality confirmed by the VVB in the verification report (verification report, 2022-02-16).

missing No evidence of baseline reassessment and missing buffer/reversal treatment; reversal events not stated (no baseline reassessment found; buffer_pool_pct not stated).

Transparency

verified Named VVB (4K Earth Science Private. Limited) and recent monitoring period provided (monitoring report/verification report, 2024 and 2025).

missing Major contradictions in reported emissions: claimed 29,262 tCO2e vs other documents reporting 4,157 tCO2e and verified figures 1,647–3,950 tCO2e, reducing reliability (verification report 2020/2022; monitoring report 2020).

Claim Safety

verified Uses national-default fuel non-renewable biomass factor (fnrb value 0.82) rather than an aggressive project-only value (monitoring/verification reports).

missing High over‑crediting risk due to inconsistent ERR figures across documents and absence of a stated leakage deduction percentage despite a claimed quantified justification (contradictions and leakage_deduction_pct not provided).

Documentation

verified Multiple documents cited (validation, monitoring, verification; n_docs_used = 18) and recent verification dated 2025-02-28.

inferred Extraction confidence is low (min_extraction_confidence = low) and one evidence doc is labelled unknown, which reduces confidence in the extracted records.

Detailed Analysis

Integrity

Additionality is supported by an investment test and explicitly confirmed by the VVB in the verification report (verification report, 2022-02-16). However, the baseline is project-level and there is no record of a recent baseline reassessment (baseline reassessment not stated), buffer pool percentage is not provided, and reversal events are not documented. The absence of a leakage deduction percentage (not stated) despite a later quantified justification increases uncertainty about leakage treatment. These gaps and missing permanence safeguards limit integrity.

Transparency

The project names the VVB (4K Earth Science Private. Limited) and provides a recent monitoring period (2024). There are 18 supporting documents and a verification report dated 2025-02-28, which is positive. However, large inconsistencies in emission reduction reporting across documents (claimed 29,262 tCO2e in one verification report vs 4,157 tCO2e in a monitoring report and verified figures between 1,647 and 3,950 tCO2e in different reports) materially reduce transparency and trust in the numbers. Low extraction confidence further weakens evidence reliability.

Claim Safety

The project uses a national-default non-renewable biomass factor (fnrb = 0.82) which is conservative relative to some project-specific assumptions. It is also not CORSIA-eligible (corsia_eligible = false), reducing double-claim risk. Nevertheless, contradictions in usage monitoring methods (annual survey vs self-report in earlier records) and mismatched ERR figures create a substantial risk of over-crediting. The leakage justification is reported as quantified in the latest verification, but the lack of an explicit leakage deduction percentage leaves the treatment of leakage unclear.

Documentation

Documentation is extensive (18 documents, including validation, monitoring and verification reports) and the most recent verification is dated 2025-02-28. The VVB is named and material findings or corrective actions are absent in the extracted records. However, extraction confidence is flagged as low and one evidence entry is 'unknown', which reduces confidence in the completeness and accuracy of the extracted dataset.

Overall

I privileged the most recent verification reports (2025-02-28 and 2022-02-16) over older documents when resolving contradictions because they are later and likely to reflect corrective updates; for example, recent verification reports state that grievance mechanisms, FPIC, safeguards and quantified leakage justification are present while older reports did not. Contradictions in reported ERR (values ranging from 1,647 to 29,262 tCO2e) and in the crediting period require caution — these inconsistencies and the low extraction confidence reduce scores across dimensions. The overall weighted score (4.1) reflects confirmed governance elements but meaningful evidence gaps and reliability issues that elevate risk of over‑claiming.

Audit Analysis

Project shows some governance and procedural strengths (VVB-confirmed additionality, named VVB, FPIC and grievance mechanisms reported in recent verification), but large discrepancies in emissions reporting, missing leakage deduction percentage and limited evidence on baseline reassessment undermine confidence and increase over‑crediting risk.

Project Description

Simoshi is a social enterprise dedicated to improving the livelihoods of low-income individuals, especially women and children. Through the installation of institutional improved cookstoves (IICS) this project brings cleaner, healthier, and environmentally friendly cooking technology to schools in Uganda, saving money, forests, emissions and improving health. Why improved cookstoves are important? About 90% of the total primary energy consumption in Uganda is generated through biomass: firewood (78.6%), charcoal (5.6%) and crop residues (4.7%). Every year 19,700 people die as a consequence of using 3-stone fires for their daily cooking activities. These traditional stoves have been associated with extremely low efficiency with 93% of the energy generated being lost during cooking. Not only does it result in indoor and outdoor air pollution, but also contributes to regional deforestation and forest degradation - from 1990 and until 2010 more than 39% of the existing forest disappeared. Currently, about 90,000 hectares (equals 900 km²) of forest cover are lost annually, which leads to fuel wood scarcity in rural areas and increasing price levels of charcoal and firewood. This project helps alleviate all these issues through institutional improved cookstoves that enable cleaner, safer, and more efficient cooking. Simoshi conducts a census approach to verify the usage rate, visiting and monitoring all schools included in the project. The IICS usage and kitchen environment are monitored at least 7 times during the year and checks are made to ensure that the replaced traditional stoves have been dismantled and are no longer in use.  Emission reductions are robustly quantified in line with the methodological approach used. Baseline fuel usage surveys are conducted and followed up by monitoring of the specific firewood consumption. This monitoring is carried out three times a year to confirm that a minimum 50% savings are achieved from all participating schools.

Red Flags

  • Large contradictions in reported emission reductions (total ERR claimed vs verified vary widely across documents).
  • Key fields not found or not quantified: leakage deduction percentage, buffer pool percentage, baseline reassessment.
  • Low extraction confidence and multiple contradictory historical verification reports reducing data reliability.

Cosa migliorerebbe questo punteggio

  • Provide a reconciled account of total emission reductions with an explanation for discrepancies between claimed and verified ERR across reports and an updated single authoritative figure.
  • Document and publish the leakage deduction percentage, buffer/reversal provisions, and the date and outcome of any baseline reassessment; improve source data quality to address extraction-confidence issues.

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