You're really not if it's in a forest. It decomposes, and lots of other plants start growing from it, including other trees. CO2 from a forest isn't really something we need to worry about. A 25 year old maple will sequester 400 pounds of co2 in it's lifetime. It can't emit more than that over the years that it decomposes. An average commuter car will emit that in 2 weeks. That's what we need to worry about.
