Pulp mills that capture biogenic CO2 need more than capture equipment to sell into carbon markets. Buyers and verification standards want evidence of where the carbon came from. That means tracing wood from harvest through suppliers and intermediaries to the mill, then connecting those records to the CO2 stream. Without that chain, a mill may struggle to prove eligibility for e-fuel or carbon removal revenue. Forest certification alone does not automatically qualify a project. Standards like Puro.earth's geological storage methodology require full pathway verification. Mills can use existing sourcing data, especially records built for EUDR compliance, as a starting point. The practical step is to compare current records with the evidence requirements of the specific carbon buyer or framework before signing an offtake agreement.
