Tree Carbon Offset Calculator
CO₂ to Offset (tonnes)
Tree Type
A tree carbon offset calculator shows how many trees are needed to offset a given CO₂ footprint. Planting should complement — not replace — emission reductions.
- 1Trees needed = CO₂ to offset (kg) / Annual sequestration per tree (kg)
- 2Convert tonnes to kg: × 1,000
- 3Trees take years to reach full sequestration rate
- 4Choose species appropriate for your climate
Offset 5 tonnes CO₂/year with deciduous trees (22 kg/yr)=5,000 / 22 = 228 trees needed
| CO₂ to offset | Deciduous (22kg/yr) | Conifer (30kg/yr) | Tropical (50kg/yr) |
|---|---|---|---|
| 1 tonne | 46 trees | 34 trees | 20 trees |
| 5 tonnes | 228 trees | 167 trees | 100 trees |
| 10 tonnes | 455 trees | 334 trees | 200 trees |
