BRASCARBON Methane Recovery Project BCA-BRA-09.

Audit Analysis

A CDM methane recovery project in Brazil with a combined additionality test and project-specific modeled baseline, but undermined by a seven-fold discrepancy between the PDD and validation report on total emissions reductions, contradictory leakage treatment across documents, and twelve material findings including calculation errors and incorrect methodology references. The project avoids inherent reversal risk (methane destruction), yet the volume of documentation defects and missing verification data significantly erodes confidence in the claimed credits.

Project Description

Red Flags

• ⚠Total ERR discrepancy of ~7× between the PDD (51,191 tCO₂e) and the validation report (358,337 tCO₂e) raises serious over-crediting risk
• ⚠Twelve material findings (CL 1–CL 12) and one corrective action (CAR 1) in the monitoring report, including calculation errors in tables B2, B6, B.6.3, B.7 and incorrect parameters WCH4,y and FCH4,m
• ⚠Leakage treatment is contradictory: the monitoring report states leakage was not addressed, while the validation report indicates it was quantified; the 0% deduction lacks a clear, consistent justification
• ⚠Farm locations in the monitoring report did not correspond to the registered project (SPCarbono 09), casting doubt on the representativeness of the monitored data
• ⚠Outdated methodology version (AMS-III.H) and Tool 06 version referenced in the monitoring report, indicating the project may not be applying the current methodological requirements
