Catalytic N2O destruction project in the tail gas of the nitric acid plant PANNA 3 of Enaex S.A.

Audit Analysis

A catalytic N2O destruction project at a Chilean nitric acid plant using the well-established ACM0019 methodology, validated by TÜV NORD CERT. The project type carries inherent permanence (no storage or reversal risk) and genuinely negligible leakage, but the absence of any monitoring data, a project-specific modeled baseline, and low extraction confidence limit confidence in the overall claim. All material findings from validation were minor and editorial in nature.

Project Description

Red Flags

• ⚠No monitoring reports or verified ERR figures found in the extracted record despite the crediting period starting in June 2022 — the project has been operational for approximately three years with no verifiable performance data available
• ⚠Minimum extraction confidence is rated low, indicating at least one key document was poorly readable, which undermines confidence in the completeness of the extracted evidence
• ⚠One of the four evidence documents is classified as 'unknown' type, creating uncertainty about the provenance and reliability of part of the documentation set
