How to Calculate Tree Carbon Offset

What is Tree Carbon Offset?

A tree carbon offset calculator shows how many trees are needed to offset a given CO₂ footprint. Planting should complement — not replace — emission reductions.

Formula

Trees needed = CO₂ to offset (kg) / Annual sequestration per tree (kg)

Step-by-Step Guide

  1. 1Trees needed = CO₂ to offset (kg) / Annual sequestration per tree (kg)
  2. 2Convert tonnes to kg: × 1,000
  3. 3Trees take years to reach full sequestration rate
  4. 4Choose species appropriate for your climate

Worked Examples

Input
Offset 5 tonnes CO₂/year with deciduous trees (22 kg/yr)
Result
5,000 / 22 = 228 trees needed
