Rio Maicimirim REDD+ Project

Audit Analysis

The Rio Maicimirim REDD+ project demonstrates solid structural integrity with a VVB-verified combined additionality test, an 11.7% buffer pool, and no reversal events over a five-year monitoring period. However, a contradiction between project-specific and jurisdictional baseline methods, an unstated leakage deduction percentage, and missing FNRB data introduce moderate uncertainty. The verified emissions reductions (2.50 million tCO₂e) represent approximately 90.5% of the pro-rata lifetime expectation for the elapsed period, indicating conservative delivery.

Project Description

Red Flags

• ⚠Baseline method contradiction: the monitoring report (Jan 2024) states a project-specific baseline while the validation report (same date) references a jurisdictional baseline — the basis for quantification is ambiguous
• ⚠Leakage is described as 'quantified' in the verification report but the actual deduction percentage is not stated in any available document
• ⚠FNRB value and method are not stated in any extracted document, leaving the forest reference level unverifiable
• ⚠28 Corrective Action Requests were raised during validation and verification, indicating a non-trivial number of documentation or methodological issues that had to be resolved
