Science: Is wood a green source of energy? Scientists are divided
"The bottom line for climate can shift depending on how far into the future researchers peer. The EPA panel on which Abt and Khanna sit has endorsed a long view. In its latest draft, the group recommends doing carbon accounting over a 100-year timeframe, based on research suggesting that it takes that long for the planet to feel the full impact of cumulative greenhouse gas emissions. Such long tallies give new forests plenty of time to mature and recapture carbon, making wood appear closer to carbon neutral."
