Audit Analysis
The Wakefield Biochar Facility 4 project exhibits severe integrity concerns, including a negative credit balance of over 5,300 CORCs, ineligible biochar stock, and a mid-period methodology change. A direct contradiction between two verification reports (915 vs 3,272 verified CORCs) undermines confidence in the reported figures. Fundamental parameters such as additionality, baseline method, and leakage treatment are absent from the available documentation.
Red Flags
- Negative balance of -5,396 CORCs reported in the verification report, indicating the project performed far below its baseline assumptions during the monitoring period
- Contradiction between two verification reports: 915.03 CORCs (Dec 2025) vs 3,272.23 CORCs (Nov 2025) for the same monitoring period — a 3.5× discrepancy
- 118.39 CORCs over-calculated due to ineligible biochar stored at WIC lacking transport-emissions evidence
- Mid-period change in measurement methodology (from shipped biochar mixed with ash/lime to before-mixing measurements) without clear justification
- No additionality test, baseline method, or leakage treatment found in any available document
