How much CO2 does a tree absorb?

A tree absorbs about 20 kg of_CO2 per year.

So, now you have the short answer right away! This is based on the estimate that one cubic meter of wood absorbs just under a ton of_CO2.

But actually, on average, a tree absorbs between 10 and 40 kg of_CO2 per year, depending on a lot of factors. All these complex variables make it no easy matter to calculate exactly how much_CO2 a tree absorbs. So let's take a closer look at them!
