🔢 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.
