B10 - Brondal #1

Audit Analysis

B10 Brondal #1 is a newly registered Isometric biochar project (crediting period 2025–2035) with a 1000-year permanence claim that is not yet supported by a buffer pool or a formal reversal risk assessment. The additionality test is described as combined but has not been independently verified by a named VVB, and leakage is deemed negligible without a quantified deduction. The project is at a very early stage with only a PDD and stakeholder consultation on file, so many MRV and verification elements are understandably absent, but the gap between the ambitious permanence claim and the current evidentiary base is the principal concern.

Project Description

Red Flags

• ⚠1000-year permanence claim with no buffer pool percentage stated and no formal, documented reversal risk assessment conducted (per the PDD)
• ⚠Additionality test described as 'combined' but no VVB name is identified and additionality has not been independently verified
• ⚠Leakage deduction of 0% justified only as 'deemed negligible' with no quantified analysis in the available documents
• ⚠No fnrb_value, usage_rate_assumed, or usage_rate_verified found in the extracted record, leaving feedstock and end-use assumptions unquantified
