Thanks to the U.S. Forest Service, Davey Tree Experts, and other partners for a very simple tool for valuing the contribution of a tree to air pollution removal;  Go to Tree Tools  to try this out.  You’ll be asked for your location information, and some simple questions about the tree.  Species, condition, diameter, sun exposure, and more, plus some information about adjacent structures.  You’ll get an analysis with a dollar amount, that will break down the types of contribution the tree provides.  No surprise, big healthy trees have more value than smaller, or unhealthy trees.

After you’ve finished entering data for one tree, you can add another tree, and another and so on.  You can get a cumulative analysis, or select the value for any one of the trees.  I have supplied an image of the report I got after I entered eight trees. (There are a lot more trees to go.)  It looks a lot like the nutrition section of packaged food label.
