Tree Planting Offset Calculator
Carbon Offset by Trees
Formula
Trees Needed = (CO2 tons x 1000) / Absorption Rate per tree. Rates: Deciduous 21 kg/yr, Coniferous 16 kg/yr, Tropical 25 kg/yr, Fast-growing 35 kg/yr.
Frequently Asked Questions
How much CO2 does one tree absorb?
A mature tree absorbs approximately 21 kg (48 lbs) of CO2 per year on average. This varies widely by species, climate, and age. Fast-growing species like bamboo can absorb significantly more.
Is tree planting enough to offset emissions?
Tree planting alone cannot solve climate change. It takes decades for trees to reach maturity, and land availability is limited. Reducing emissions at the source is far more effective, with tree planting as a complementary strategy.
