*because paper fibers can be recycled at most three times, the carbon they contain will eventually enter the environment in some way.
Figures based upon estimation of 17 reams produced per tree and C02 emission of 6.5lbs per ream.
Calculations do not include the lost carbon sequestration potential of trees cut down. An average tree sequesters roughly one ton of CO2 each century, and trees often live for many centuries. |
