Distribution of Improved cook stove - Phase 22

Integrity

The extracted record indicates additionality was confirmed by the VVB (validation/verification documentation referenced) and reports no material findings or corrective actions. However, the baseline method and the timing of any baseline reassessment are not stated in the extracted record, which is a major integrity gap for a cookstove ER calculation. Leakage is described as quantified in the monitoring report (2023), but the actual leakage deduction percentage is not stated in the extracted record, reducing confidence that leakage was conservatively applied.

Transparency

The monitoring report (2023-12-11) clearly states the monitoring period (2012-10-08 to 2017-10-07) and provides total verified emission reductions of 60,865. The project also discloses the monitoring approach as annual surveys in the extracted record. But the total claimed ERs, usage-rate assumed, and usage-rate verified are not stated in the extracted record, making it difficult to independently reconcile how the verified total was derived.

Claim Safety

The monitoring report (2023) provides an fNRB value of 87.9% and notes it was calculated using secondary sources, which can be acceptable but is sensitive to assumptions and national default comparisons that are not provided in the extracted record. Missing baseline method, leakage deduction percentage, and usage-rate metrics increase the risk of over-crediting and therefore the risk of unsafe claims. CORSIA eligibility and CCP status are not stated in the extracted record, so buyers cannot easily assess eligibility-based claim constraints from the extracted data alone.

Documentation

The evidence set is relatively strong: the extracted record lists a PDD, validation report, monitoring report, and issuance, with 12 documents used and high extraction confidence. The monitoring report is recent (2023-12-11) relative to the monitoring period and crediting period. However, an internal inconsistency on the crediting-period dates between core documents reduces documentation reliability.

Overall

Overall scoring is pulled down mainly by missing integrity-critical parameters (baseline method, leakage deduction percentage, and usage-rate assumed/verified) despite otherwise decent document coverage and VVB involvement. The key contradiction is the crediting period: the monitoring report (2023-12-11) states 2012-10-08 to 2022-10-07, while the PDD (2021-01-15) states 2012-12-31 to 2022-12-30. I privilege the monitoring report dates because it is more recent and typically reflects the implemented/registered crediting timeline used for issuance, but the discrepancy still indicates data reliability issues and warrants a score penalty.
