Sustainable procurement of wood and paper
A tree's ability to capture CO₂ depends on several factors, including its species, age, wood density, growth rate, climate, soil quality, and water supply. For instance, a mature beech tree, around 80 years old and with a dry mass of 600 kilograms in leaves, branches, trunk, and root system, can capture one tonne of CO₂. This means that a beech tree can absorb 12.5 kilograms of CO₂ per year. Therefore, to offset one tonne of CO₂ annually, 80 trees would need to be planted. This emphasises the significance of sustainable forest management, where tree populations are meticulously controlled.
