🔢 Carbon Removal Calculation
✓ Methodology: EBC / IPCC Tier 2
Annual Biochar Production 200 t/yr
Carbon Content (lab-verified) 72%
H/C Molar Ratio (EBC Class A) 0.35
Stability Factor 1.0 (100-yr permanence)
Gross CO₂e Removed 2,600 tCO₂e/yr
− Project Emissions (energy + transport) −160 tCO₂e/yr
− Buffer Reserve (10%) −244 tCO₂e/yr
NET Carbon Credits 2,196 tCO₂e/yr
🔗 Supply chain GPS waypoints are logged automatically by field collectors using the Verdini Field app. Each step is timestamped and immutable. Transport emissions are calculated per IPCC/DEFRA factors.
