You might know that trees help take carbon dioxide out of the atmosphere.
But do you know how much carbon that tree in your front yard is storing in its roots and branches?
The Tree Carbon Calculator makes it very simple and easy for you to quantify the carbon benefit of a tree.
It's an online tool that asks you to plug in just three pieces of information about your tree.
Just entering the climate region in which you live, the species of tree, and either its size or its age.
The calculator then estimates how much carbon dioxide has been stored in the tree over the past year, and its entire lifetime.
A big, large oak tree, for example, stores thousands of pounds of carbon.
A small crab apple tree will not store anywhere near that much.
If the tree shades and cools your house, a few more pieces of information could tell you how much energy your tree is saving you.
