How much CO2 does a tree extract from the atmosphere?

The answer to this question of course varies greatly. Without a doubt, we must acknowledge the following unique and exogenous factors: tree type, length of the vegetation period, water supply, and soil condition.
The most reliable evidence shows that a single-hectare forest absorbs about 3.8 tonnes of carbon which equates to circa 13.82 tonnes of CO2 per year. This again fluctuates depending on an individual tree's soil condition, water supply, vegetation, etc.

Sources exist that assert that a single Beech tree absorbs about 6 kilograms of CO2 per day (2,190 kg p.a.). From our viewpoint, this kind of information is exaggerated since it would signify that all Beech trees we plant would survive until the end of their natural growth periods.

Our findings contrast with these figures, however ours are still quite conservative from an environmental standpoint. We estimate that only every 20th tree reaches full size and the other trees are stubbed (die) during their growth period either from natural displacement or through planned deforestation. We count on an average value of 0.027 kg CO2 per day and per tree (10 kg CO2 per year). This value is logically lower if the tree is smaller during the early years - it would level itself out from the average during its appropriate growth period. To simplify the calculation, we have averaged the total CO2 absorption of a tree's lifespan and divided it by the number of days to derive a daily value figure.

Our figures are not in ever case an accurate outlook regarding CO2 absorption hence they are a conservative estimate at best. We would like, in spite, to show that with this counter it is worthwhile to plant trees and with every new day a tree is planted, the global climate benefits.
