2-2-5- Step 5: Estimating annual carbon sequestration in
an individual tree unit
The absorption of atmospheric carbon or carbon sequestration is the
amount of fixed carbon in tree biomass in a given time. Generally,
carbon sequestration is measured within a year and is based on a
kilogram or gram per year.
In order to calculate the average amount of the annual carbon storage,
we assumed that the average diameter growth is 0.61 cm per year based on
the previous evidence (table 2). Also, since most of the trees were
categorized in the moderate and old class, therefore, the average annual
growth of their height was considered 15 cm per year.
