How to Calculate Tree Carbon

What is Tree Carbon?

Trees sequester CO₂ through photosynthesis, storing carbon in their woody biomass and roots. Sequestration rates vary by species, age, and climate.

Formula

Carbon sequestration ≈ 20 kg CO₂/tree/year (average, mature) | 100 trees offset ~20,000 kg CO₂ over 40 years

Step-by-Step Guide

  1. 1Deciduous trees (UK): ~22 kg CO₂/tree/year
  2. 2Conifers: ~30 kg CO₂/tree/year
  3. 3Tropical trees: ~50+ kg CO₂/tree/year
  4. 4Total stored ≈ Annual rate × Years × Number of trees

Worked Examples

Input
50 oak trees, 15 years after planting
Result
CO₂ stored ≈ 50 × 22 × 15 = 16,500 kg = 16.5 tonnes
