OBIO Rudshøgda

Audit Analysis
OBIO Rudshøgda is a Norwegian biochar removal project under the Puro standard with a reasonable 1,000-year permanence claim and a present LCA, but it suffers from significant gaps in additionality verification, permanence safeguards (no buffer pool), and leakage treatment. A material finding of recording errors in biochar stock was identified and corrected, and multiple contradictions across documents (crediting period, safeguards status) reduce confidence in the data record.
Red Flags
- Additionality (investment test) was not independently verified by the VVB, leaving the core additionality claim unconfirmed
- No buffer pool percentage is stated for a 1,000-year permanence claim, leaving reversal risk unmitigated
- No leakage deduction or justification is provided in any available document
- Material finding: recording errors in biochar stock (units vs volume, wrong quarter) caused a 0.52 CORC undercalculation, requiring corrective action
- Crediting period is contradictory: the verification report states 2023-01-01 to 2024-03-31 while the issuance record shows 2021-01-01 to 2025-12-31
