GS1005 Qori Q'oncha - Improved cookstoves diffusion programme in Peru - VPA5

Audit Analysis

The Qori Q'oncha cookstove diffusion programme in Peru is a methodologically sound project with VVB-confirmed additionality and a recently reassessed baseline, but it is burdened by 28 corrective actions, 12 cross-document contradictions on key parameters (fNRB, leakage, ERR figures), and the absence of a buffer pool. The project-specific baseline and a 9-percentage-point gap between assumed (90%) and verified (81%) usage rates introduce moderate over-crediting risk. Overall, the project is functional but carries elevated data-reliability and documentation-compliance concerns that temper confidence in its credit quality.

Project Description

Red Flags

• ⚠28 corrective actions required across verification and monitoring cycles, including parameter misalignment with the PoA-DD and VPA-DD, missing SDG parameters, and incomplete MR templates
• ⚠fNRB value contradicts between documents: 73.75% (verification report, 2018) vs 0.8726 (monitoring report, 2024) — a 13.5-percentage-point discrepancy that directly affects ER calculations
• ⚠No buffer pool is in place to cover permanence risk, and no reversal events data has been reported
• ⚠Leakage deduction is reported as 0% in the 2018 verification report but 1.01% in the 2022 monitoring report, with the justification shifting from 'quantified' to 'deemed negligible' across documents
• ⚠Usage rate assumed at 90% (capped per Gold Standard) versus 81% verified in the field — a 9-percentage-point gap that inflates claimed reductions relative to observed behaviour
