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

The calculator uses the standard published formula for tree carbon offset. Results are accurate to the precision of the inputs you provide. For financial, medical, or legal decisions, always verify with a qualified professional.

This calculator works with kilograms, inches. You can enter values in the units shown — the calculator handles all conversions internally.

The core formula is: Trees needed = CO₂ to offset (kg) / Annual sequestration per tree (kg). Each step in the calculation is shown so you can verify the result manually.
