Fever Tree Profile
The Coppice & Carbon Engine
- Triple regrowth on coppicing — 5-10 heavy stems replace each cut within 18 months
- Nitrogen-fixing root system restores tobacco-depleted soils
- Wood density: 532 kg/m³ | Calorific value: 18.4 kJ/g
- Carbon sequestration: 5.4 tCO₂/ha/year — Gold Standard eligible from Year 3
- Three coppice cycles (Y4, Y8, Y12) supply fuel + biochar feedstock
- Riparian species — regulates water cycle (unlike Eucalyptus)
- Year 15 clearfell: 280 stems/ha | 15.4 m³/ha | $380/m³ | $5,852/ha
Albizia Profile
The Productive Middle Layer
- Rapid early canopy growth (2-3 m/yr) suppresses weeds, protects Teak seedlings
- Air-dried density: 640-790 kg/m³ — premium fuel wood
- Selective thinning at Year 8 opens canopy for Teak, generates first timber income
- Excellent nitrogen fixer — complements Fever Tree soil restoration
- Year 15 clearfell: 180 stems/ha | 18.0 m³/ha | $460/m³ | $8,280/ha
Revenue Streams
| Revenue Stream | Activation | Details |
|---|---|---|
| Carbon credits (ARR) | Year 3 | 5.4 tCO₂/ha/yr at $37/t — investor receives 80% |
| Biochar credits (BCR) | Year 3 (coppice Y4, Y8, Y12) | ~2 t/ha/yr at $177/t — investor receives 80% |
| Timber harvest | Year 15 | Fever Tree: $5,852/ha + Albizia: $8,280/ha = $14,132/ha gross |
| Replanting | Year 16 | Second cycle begins — funded from harvest proceeds |

Calculation Transparency
Carbon sequestration rate (ARR): 5.4 tCO₂/ha/year — Vachellia/Albizia dryland ecosystem, peer-reviewed
Biochar yield (BCR): 2.0 tCO₂e/ha/year — Fever Tree coppice prunings processed at mobile kilns
Integrity margin: −10% applied to gross CO₂ for credit issuance
Timber price: Fever Tree $380/m³ | Albizia $460/m³ — conservative 2026 market rates
