🌍 Carbon Sequestration: Unlocking Nature’s Role in Climate Action
Forests are vital carbon sinks, capturing and storing CO₂ in biomass, soil, and organic matter — a process known as carbon sequestration.
To assess their contribution to climate mitigation and carbon credit projects, we quantify carbon stocks at plot scale using the following components:
📊 1️⃣ Above-Ground Biomass (AGB)
AGB = 0.0673 × (ρ × D² × H)⁰·⁹⁷⁶
(ρ = wood density, D = diameter, H = height)
📊 2️⃣ Below-Ground Biomass (BGB)
BGB = 0.26 × AGB
📊 3️⃣ Dead Organic Matter (DOM)
≈ 5–10% of AGB
📊 4️⃣ Soil Organic Carbon (SOC)
SOC = SOC% × BulkDensity × Depth × Area
Total Carbon Stock = AGB + BGB + DOM + SOC
🧮 Worked Example (Simplified)
Given:
ρ = 0.6 g/cm³, D = 30 cm, H = 15 m, SOC% = 2%, BulkDensity = 1.3 g/cm³, Depth = 0.3 m, Area = 100 m², DOM = 7% of AGB
✅ AGB ≈ 512 kg
✅ BGB = 133.12 kg
✅ DOM = 35.84 kg
✅ SOC = 780 kg
➡️ Total = 1,460.96 kg (≈ 1.46 tonnes C per plot)
🌱 By valuing and quantifying nature’s carbon storage capacity, we empower better climate action, ESG reporting, and sustainable resource management.
