Project Carcará

Audit Analysis

Project Carcará is a small-scale (256 tCO₂e) enhanced weathering carbon removal project with VVB-confirmed additionality and no reported reversals, but it carries a notable number of material findings (13) and corrective actions (10) that raise concerns about MRV robustness. The absence of independently tested carbon content, unverified storage, and two inter-document contradictions (permanence and leakage) temper confidence in the credit's integrity. The project is early in its crediting period with no verified ERR yet available for comparison.

Project Description

Red Flags

• ⚠Thirteen material findings in the verification report, including two nonconformities (rain gauge not used; sampling protocol not followed) and two misstatements (limestone application emissions factor likely underestimates emissions; porewater temperature measurement procedure not as described in the PDD)
• ⚠Carbon content was not independently tested and storage was not independently verified, leaving the core carbonation claim reliant on the proponent's own lab data
• ⚠Permanence claim differs by a factor of ten between the PDD (1,000 years) and the validation report (10,000 years)
• ⚠FPIC was not conducted despite the project operating on agricultural land with local stakeholders
• ⚠No verified ERR figure is available in the extracted record, preventing any over- or under-delivery assessment
