BBB - Ahlstrom_Radcliffe
#3of 44 in Biochar#1of 8 in United Kingdom#4of 109 in Puro.earth (PUR)
Audit Analysis
The Black Bull Biochar project at Ahlstrom Radcliffe demonstrates a solid additionality case confirmed by the VVB via an investment test, and the first monitoring period shows strong over-delivery relative to the lifetime estimate. However, several material findings around measurement accuracy and LCA completeness, combined with the absence of a stated leakage treatment and buffer pool, leave meaningful gaps in the integrity and transparency picture.
Red Flags
- Five material findings in the verification report, including LCA omissions (diesel, wastewater) and biochar mass measurement limitations, with four corrective actions still pending
- Leakage deduction and justification are not stated in any available document, leaving the treatment of potential biochar loss or misapplication unaddressed
- No buffer pool percentage or explicit permanence risk assessment found in the extracted record for a sequestration-type project
