Urban and Suburban Tree Species Carbon Sequestration Calculator
The calculator uses the the methodology described in Method for Calculating Carbon Sequestration by Trees in Urban and Suburban Settings to compute the amount of carbon sequestered in a single tree. Their database includes 100 tree species.
Each species is categorized as type hardwood (H) or conifer (C). Its growth rate is specified as slow (S), moderate (M) or fast (F).
The annual carbon sequestration rate (pounds / year) is based on the age of the tree, its type and its growth rate. See the above reference for sequestration rates used by the calculator. Tree diameter and height are not used to compute sequestration rates but are implied by the tree age.
The sequestration rates are for open-grown trees, not for forest-grown trees in stands.
To use the calculator specify a tree age from 0 to 59 years, number of trees per species (same for all species) and select one of more tree species from the drop-down list. Then click on the Compute Carbon Sequestered button.
For each tree species selected the calculator computes and displays the annual carbon sequestered in pounds and the carbon dioxide (CO2) equivalent (carbon sequestered * 3.6663) in pounds for a single tree. It then computes the total annual carbon sequestered and the carbon dioxide (CO2) equivalent for the number of trees specified per species.
Note: There are many carbon sequestration methodologies for trees and their results can differ greater.
