Forests in the eastern US currently store an estimated 8.5 Pg (1 Pg (pentagram) is equivalent to 1015 g or 1 billion (109 metric tons) of C in the aboveground components of live growing stock (Miles, 2016), roughly 20 percent of all C stored in living and dead plants and soil organic matter in forests of the conterminous United States.

U.S. forests offset nearly 13 percent of total U.S. carbon dioxide emissions. Of that 13 percent offset, aboveground forest biomass dynamics represented the single largest contribution at nearly 50 percent (the United States Environmental Protection Agency).
