BUENOS AIRES RENEWABLE ENERGY PROJECT

Audit Analysis

The Buenos Aires Renewable Energy Project (GS-309) is a Gold Standard renewable energy avoidance project in Brazil with VVB-confirmed additionality and no reported reversal events, but its integrity is significantly undermined by four material findings including non-compliance with site-visiting frequency requirements and a 19,062 tCO2e deduction (38% of claimed ERs) for prior-period non-compliance. Nine contradictions across documents—spanning leakage justification, ERR figures, FNRB units, additionality test type, and safeguards—raise concerns about data consistency and MRV reliability. The project over-delivered relative to its pro-rata expectation for the 2017–2019 monitoring period, but the absence of a buffer pool, unknown CCP/CORSIA status, and project-specific baseline limit confidence in the credit's long-term integrity.

Project Description

Red Flags

• ⚠Site-visiting frequency did not meet Gold Standard requirements during the 2017–2019 monitoring period, triggering a Forward Action Request and a 19,062 tCO2e deduction (38% of the 49,612 tCO2e claimed)
• ⚠Nine contradictions between documents, including conflicting leakage justifications ('quantified' vs 'deemed negligible'), conflicting additionality test types ('investment' vs 'combined'), and conflicting FPIC status (false in validation report vs true in 2013 stakeholder consultation)
• ⚠CCP status and CORSIA eligibility are both not stated in any available document, leaving dual-channel risk unassessed
• ⚠The deviation request to convert the fixed crediting period to a renewable 5×3-year structure was not approved, indicating the project could not extend its crediting period
