Analysis

The Utsil Naj cookstove project in Mexico is a long-running Gold Standard avoidance project (since 2011) with VVB-confirmed additionality and no reported reversals, but it carries moderate risk from a project-specific baseline, absence of a buffer pool, a weak leakage justification, and a significant FPIC contradiction between the PDD and the validation report. Multiple material findings and corrective actions related to fNRB parameter corrections and documentation template updates indicate ongoing quality-control issues that temper confidence in the credit volumes.
