Analysis

The Black Bull Biochar project at Ahlstrom Radcliffe has a VVB-confirmed investment additionality test and delivers verified credits close to its claims (96.3% of the claimed figure for the reporting period). However, the verification report identified five material findings—including incomplete LCA coverage and measurement procedure gaps—along with four required corrective actions, and key integrity elements such as buffer pool allocation and leakage treatment are not documented in the available record.
