CUFR Tree Carbon Calculator Now National

The Center for Urban Forestry Research’s Tree Carbon Calculator (CTCC) is now national. The CTCC is programmed in an Excel spreadsheet, just like the old one, but now covers 16 US climate zones. This verision includes new features: palm species, emissions factors and energy information. Now users from coast to coast can enter species, tree size (diameter-at-breast height) or tree age and receive information on the amount of biomass and carbon stored in the tree, as well as benefits associated with energy conservation projects.

All results are based on tree growth data from each of the 16 climate zones. To learn more or download this application, visit the U.S. Forest Service’s Climate Change Resource Center website. A help menu and list of frequently asked questions are included online with the CTCC. Additional technical assistance is available via email at
