Audit Analysis
The Planeteers Elbe Engineered Enhanced Weathering project is a pre-operational carbon removal project (crediting period begins January 2026) validated by Normec Verifavia SAS under the Isometric standard. Additionality is VVB-confirmed and storage is independently verified, but the 1,000-year permanence claim lacks a buffer pool, no leakage treatment is documented, and carbon content has not been independently tested. The project is at an early stage with no monitoring data yet, and two contradictions between the PDD and validation report introduce minor reliability concerns.
Red Flags
- 1,000-year permanence claim for enhanced weathering with no buffer pool or reversal-risk mitigation documented
- No leakage deduction or leakage justification stated in any available document
- Carbon content of the captured/stored material has not been independently tested
- Two contradictions between the PDD (May 2024) and validation report (Dec 2025) on additionality test type and energy source
