IPCC & Chave Compliant Allometric Carbon Estimation.
Explore how 3D geometric telemetry (DBH and tree height) is mathematically converted into aboveground biomass (AGB), belowground root biomass (BGB), and verifiable equivalent carbon (CO₂e).

Chave et al. (2005) Biomass Equation
Widely applied for tropical moist forest biomass accounting. Integrates species-specific wood density (ρ), breast-height diameter (DBH in cm), and total tree height (H in meters).
Belowground Root Ratio (Cairns et al. 1997)
Subterranean root biomass is estimated via Cairns' empirical non-linear allometric relationship, ensuring auditable and comprehensive tree carbon accounting.
IPCC Carbon Fraction & CO₂ Equivalent Conversion
Per IPCC Tier-1 forestry guidelines, dry wood biomass contains 47% carbon (0.47). Total carbon stock is converted to CO₂ equivalent using the molecular-to-atomic mass ratio of carbon dioxide to carbon (44/12 ≈ 3.6667).
