CARBON BUDGET OF UNITED STATES FORESTS
Q: How much carbon could be sequestered if higher
rates of recycling were encouraged?
A: This scenario increases recycling
by increasing the percentage of wastepaper used as raw material
for paper production. Approximately 9 MMT/yr of carbon could be
sequestered above the base projection (Birdsey and Heath, 1995).
For more information about the scenario, see Haynes and others (1995).
For additional information about recycling, see Heath and Birdsey
(1993), Ince and others (1995), and Skog and others (1996).
