Rio Negro Ceramic Fuel Switching Project

Audit Analysis

The Rio Negro Ceramic fuel-switching project has a sound core methodology (AMS-I.E.) with VVB-confirmed additionality and a quantified 5% leakage deduction, but is undermined by 12 cross-document contradictions—including a significant FNRB discrepancy (93.8 vs 0.8209)—14 corrective action requests, an expired clay extraction licence, and the absence of an environmental management system. The project is inherently low-risk on permanence (energy sector, no carbon storage), yet operational fragility (100% workforce turnover from flood losses) and a project-specific baseline that has not been reassessed introduce material uncertainty into the long-term credit validity.

Project Description

Red Flags

• ⚠FNRB value contradicts between the 2024 verification report (93.8, national default) and the 2022 monitoring report (0.8209, local field), a discrepancy of roughly 14 percentage points that directly affects the ER calculation
• ⚠14 Corrective Action Requests and 12 corrective actions were raised in the 2024 verification, including installation of a chimney filter, rebuilding of flood-damaged areas, and refurbishment of the Hoffman kiln—indicating significant operational non-conformities
• ⚠Clay extraction licence had expired at the time of verification, with renewal only 'requested', raising a legal-compliance risk for continued operation
• ⚠Workforce turnover surged from 45% to 100% due to flood losses, and no environmental management system is in place, signalling operational fragility
• ⚠FPIC was not conducted (per the 2024 verification report), despite a monitoring report from the same year claiming it was done—a direct contradiction on a VCS safeguard requirement
