The Butterfly Effect

Integrity

The monitoring report (2020) indicates additionality was confirmed by the VVB, which supports integrity at a high level. However, the extracted record does not state the baseline approach used, when (or whether) the baseline was last reassessed, or any quantified leakage deduction, all of which are central to cookstove credit integrity (PDD, 2020-08-12; monitoring report, 2020). As an avoidance project, reversal risk is typically low, but the extracted record does not provide any buffer or reversal treatment details, so conservatism is warranted.

Transparency

The monitoring report (2020) clearly states the monitoring period (2019-04-16 to 2021-06-30) and describes usage monitoring via annual surveys, which is a positive MRV transparency signal. At the same time, the extracted record does not include total emission reductions claimed or verified, nor the VVB name, limiting independent scrutiny and registry-style completeness from the available documents (PDD, 2020-08-12; monitoring report, 2020).

Claim Safety

Cookstove crediting is highly sensitive to the fraction of non-renewable biomass, and the extracted record contains a major inconsistency: the monitoring report (2020) lists 0.8628 while the PDD (2020-08-12) lists 86.28, which cannot both be correct as a fraction. This contradiction increases the risk of over-crediting and weakens confidence in downstream claims. In addition, CORSIA eligibility and CCP status are not stated in the extracted record, so buyers cannot easily screen for aviation/CCP-related claim constraints based on the available information (PDD and monitoring report).

Documentation

Two core documents are present (PDD and monitoring report) and the extraction confidence is high, which supports a mid-range documentation score (extracted metadata). However, multiple key quantitative and attribution fields are not found in the extracted record (baseline method, ERR totals, VVB name, leakage deduction), suggesting the available documentation (or the extracted content) is incomplete for a robust quality assessment (PDD, 2020-08-12; monitoring report, 2020). No material findings or corrective actions are reported in the extracted record (monitoring report, 2020).

Overall

Overall quality is moderate but constrained by missing core quantification details and a significant internal inconsistency on the fraction of non-renewable biomass. For the contradiction, the monitoring report value (0.8628) is privileged because it is the operational MRV document used for issuance-period accounting and the PDD value (86.28) appears to be a unit/formatting error (percent vs fraction), but the inconsistency still indicates documentation reliability risk and warrants a score penalty. If documentation were to score below 3.0, transparency would be capped by the gate rule; and if integrity were below 4.0, the overall score would be capped at 6.0 (applied post-scoring).
