Feedstock integrity is the first condition for credible removals. When biomass origin is unclear, carbon balance becomes uncertain and certification risk rises.

Why it matters
• Unsustainable residues reverse climate benefit.
• Methodologies require proof of legal sourcing.
• Buyers expect basic land-use transparency.

What certification bodies will expect
• Evidence of legal harvest or legal processing.
• Documents that match stated residue volumes.
• Disclosure of upstream land-use conditions.
• A chain of custody that fits the scale of operations.

What buyers should request
• Documented feedstock origin.
• Supplier permits.
• A short risk assessment.
• A mitigation plan.
• Traceability notes.

Practical takeaways
• Do early due diligence.
• Share evidence before signing offtake agreements.
• Update documentation when conditions change.

Integrity starts with the feedstock. Clear sourcing protects climate value and helps avoid certification delays.
