Proyecto Mirador Enhanced Distribution of Improved Cookstoves in Latin America – Second VPA for Distribution of Dos por Tres Cookstoves in Guatemala

Audit Analysis

A long-running Gold Standard cookstove PoA (since 2015) with VVB-verified additionality and quantified leakage, but plagued by a large fNRB discrepancy between verification cycles (35% vs 79.28%), a 14-percentage-point usage-rate gap (90% assumed vs 76% verified), and an extensive history of corrective actions across multiple monitoring periods. The project is CCP-eligible and actively monitored, yet the volume of unresolved clarifications and parameter inconsistencies raises meaningful over-crediting and data-reliability concerns.

Project Description

Red Flags

• ⚠fNRB value dropped from 79.28% (2024 verification report) to 35% (2026 verification report) — a 44-percentage-point swing in a core ER parameter that materially changes the emission-reduction calculation and is not adequately explained in the extracted record
• ⚠Usage rate assumed at 90% in the design but verified at only 76% in the 2026 verification report, indicating a 14-percentage-point underperformance that was not reflected in the ex-ante estimate
• ⚠Over 40 corrective actions and clarifications logged across multiple verification cycles (2020–2026), including repeated errors in ER spreadsheets, non-CO₂ emission-factor application, and baseline/PE/Net-ER mismatches, suggesting persistent MRV quality issues
• ⚠fNRB method is reported as 'local_field' in the 2026 verification report but 'national_default' in the 2026 monitoring report for the same period — an unexplained methodological inconsistency within a single reporting cycle
