WHY CUTTING TREES TO BURN THEM INCREASES
EMISSIONS FOR DECADES TO CENTURIES
•
Much of every tree (roots & slash) left in forest, decays & emits carbon
•
25%-30% of wood used in wood pellet plant & emits carbon
•
Burning wood emits much more carbon up smokestack than natural gas
•
For 5-10 years re-growing trees grow slower than most trees if left alone
•
Even decades later after first tract of forest regrows enough to payback
carbon debt, newer tracts still in debt.

Biofuels cause far
more emissions than
even gasoline or diesel
if food is replaced at
the global average land
cost.

IPCC Guidelines
IPCC 2000 Land Use Report (p. 355):
Because
fossil fuel su stitution is already re arded y
excluding emissions from the combustion of
bioenergy,
to a oid underreporting . . . any
changes in biomass stocks on lands . . . resulting
from the production of biofuels would need to be
in luded in the a ounts.
