tree maturity

A mature tree absorbs roughly 48 lbs (0.022 metric tons) of CO₂ per year.
Newly planted trees take about 10 years to reach maturity, absorbing progressively more CO₂ each year as they grow.
Spacing of 400 trees per acre is typical for reforestation projects.
Cost estimate of $1 per tree reflects bulk seedling pricing through non-profit reforestation programs.
