Score Breakdown

Integrity

verified Additionality was confirmed by the VVB, and the monitoring report reports no material findings or corrective actions.

missing Baseline reassessment timing is not stated, and leakage deduction is not found in the extracted record despite a later note that leakage was quantified.

Transparency

verified The project has a named VVB, a defined monitoring period, and a quantified verified emissions reduction figure in the monitoring report.

missing The extracted record shows contradictions in usage monitoring method, crediting period, and verified emissions totals, which weakens reporting clarity.

Claim Safety

verified The verified usage rate is high at 87.94%, above the assumed 80%, which supports stronger real-world performance than assumed.

missing The baseline is project-specific rather than clearly standardized or recently reassessed, and leakage treatment is not fully evidenced in the extracted facts.

Documentation

verified Eighteen documents were used, with a medium extraction confidence and supporting safeguards such as FPIC and a grievance mechanism.

missing Some key fields are not stated in available documents, including buffer pool percentage, leakage deduction, and the exact additionality test type.

Detailed Analysis

Integrity

The monitoring report dated 2024-12-24 confirms additionality was verified by the VVB, and it reports no material findings or corrective actions required. The project also uses a project baseline, but the last reassessment date is not stated in available documents. Leakage is not fully transparent because the extracted facts say it was quantified, yet the actual deduction percentage is not found.

Transparency

Transparency is helped by the presence of a named verifier, a defined monitoring period, and a verified emissions reduction figure of 1,008,534. The project also uses annual survey-based usage monitoring in the latest report. However, the extracted record contains contradictions in the usage monitoring method, crediting period, and verified emissions totals, which reduces clarity and makes the reporting less straightforward.

Claim Safety

Claim safety is moderate because the verified usage rate of 87.94% is stronger than the assumed 80%, suggesting the project may be performing better than modeled. At the same time, the baseline is project-specific rather than clearly standardized, and the leakage treatment is not fully evidenced in the extracted facts. The project is an avoidance cookstove activity, which lowers permanence concerns, but over-crediting risk cannot be ruled out from the available record.

Documentation

Documentation quality is fair: 18 documents were used, the extraction confidence is medium, and the record includes FPIC, benefit sharing, and a grievance mechanism. The monitoring report is recent, but several important items are not stated in available documents, including buffer pool percentage, exact leakage deduction, and the additionality test type. Those gaps limit how fully the project can be assessed from the extracted record alone.

Overall

Overall, this appears to be a credible but not top-tier project file: the VVB confirmation of additionality and absence of material findings are positives, but several inconsistencies reduce confidence. I privileged the latest monitoring report for the quantified usage rate, leakage description, and verified emissions figure because it is the most recent and specific source, while noting that earlier documents conflict on usage method, crediting period, and emissions totals. Those contradictions are explicitly reflected in the lower transparency and claim-safety scores.

Audit Analysis

This is a reasonably documented Gold Standard cookstove project with VVB-confirmed additionality, no material findings, and a quantified usage rate close to 88%. However, several key elements are either missing or inconsistent across documents, including the baseline reassessment timing, leakage treatment, and crediting-period/usage-method details, which keeps confidence from being high.

Project Description

This project promotes the transition of families to BURN's Jikokoa, one of the world’s most fuel-efficient charcoal stoves. The use of open fires and solid fuels for cooking is one of the world’s most pressing health and environmental problems, directly impacting close to half the world’s population and causing 132K premature deaths in Nigeria each year. The cooking sector accounts for 2% of annual global carbon emissions estimates. Today, 83% of Nigerians lack access to clean cooking, with 31% of the population living on less than $2.15 a day. This project allows clean and efficient cookstoves to be distributed at a subsidised price, enabling access to Nigerian families who otherwise could not afford them. The stoves result in a ~85% reduction in indoor air pollution and ~60% reduction in fuel consumption, meaning improved health outcomes, reduced deforestation, $6 per week in savings per family and cooking time saved. The carbon credits are certified by internationally recognised body Gold Standard. The project is operated by BURN, Africa’s leading cookstove company. BURN stoves have impacted over 24M lives, and BURN operates the only modern cookstove manufacturing facility in Nigeria. The project is financed by Key Carbon, a Canadian entity with a mission to accelerate climate action. Project Impacts and Benefits The project’s impact on 8 SDGs has been certified by Gold Standard. Since the project’s launch in 2021, the project has had the following impacts: Climate action : 590K tonnes of CO2e avoided. The Jikokoa stove reduces fuel consumption by 64%, resulting in a decrease in both CO2 and non-CO2 emissions from cooking. Furthermore, by reducing the demand for biomass, the project contributes to slowing down deforestation. Affordable and clean energy : 119K households with access to clean cooking. Good health and well-being: 94.3% of households experienced perceived improved air quality. Cooking-related smoke inhalation is responsibl

Red Flags

  • Leakage treatment is not fully clear because one record says it was deemed negligible while the later monitoring report says it was quantified, but the actual deduction is not stated in the extracted facts.
  • The reported crediting period and usage monitoring approach differ across documents, and total verified emissions reductions also vary materially between records, indicating some reliability risk.

Cosa migliorerebbe questo punteggio

  • Provide the exact leakage deduction and the underlying calculation used in the latest monitoring report.
  • Publish a reconciled document trail explaining the differences in usage monitoring method, crediting period, and verified emissions totals.

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