How to use the tree carbon storage calculator
Estimate CO₂ stored by trees. Enter number of trees, average trunk diameter in the fields above; the carbon stored, co2 equivalent are computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- n — Number of trees
- d — Average trunk diameter (cm)
Worked example
With number of trees = 100, average trunk diameter = 30 cm, the calculator gives carbon stored ≈ 2,250 kg; co2 equivalent ≈ 8,250.75 kg.
Frequently asked questions
What is the formula for the tree carbon storage calculation?
Carbon stored (kg) = n × 0.25 × d^2 × 0.1. CO2 equivalent (kg) = [Carbon stored] × 3.667. Here n is number of trees, d is average trunk diameter (cm).
What inputs do I need for the tree carbon storage calculator?
You need number of trees, average trunk diameter in cm. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
