Rio Bravo Climate Action Project

Audit Analysis

The Rio Bravo project is a VCS ALM soil-carbon project in Belize with a VVB-verified barrier additionality test and a 10% buffer pool, but it carries significant concerns: leakage was not properly addressed (0% deduction with no justification per the verification report), a 2011 monitoring report reported reversal events that the 2023 verification report says did not occur, and the verified ERR figure is an exact digit-for-digit match to the lifetime ex-ante estimate, raising questions about independent verification. Multiple contradictions between the verification report and the issuance record further erode confidence in the project's data integrity.

Project Description

Red Flags

• ⚠Verified ERR (1,660,260 tCO2e) is an exact match to the lifetime ex-ante estimate (1,660,260 tCO2e), suggesting the verified figure may have been copied rather than independently calculated
• ⚠Leakage deduction is 0% and the verification report states leakage was 'not addressed', while the monitoring report claims it was 'deemed negligible' — no quantified justification exists in the authoritative document
• ⚠The 2011 monitoring report reported reversal events, but the 2023 verification report states no reversals occurred — an unexplained contradiction that undermines confidence in the permanence record
• ⚠Three material findings in the verification report, including a deviation from the project description to account for 203,073 tCO2e of enhancements based on a 2021 inventory, and use of a different methodology version (v1.6 vs v1.1)
• ⚠Low extraction confidence across the document set, with one document of unknown type, limiting the reliability of the extracted record
