How much CO2 does one tree absorb (per year or per lifetime)?
Answer:
Each person in the U.S. generates approximately 2.3 tons of CO2 each year. A healthy tree stores about 13 pounds of carbon annually -- or 2.6 tons per acre each year. An acre of trees absorbs enough CO2 over one year to equal the amount produced by driving a car 26,000 miles. An estimate of carbon emitted per vehicle mile is between 0.88 lb. CO2/mi. – 1.06 lb. CO2/mi. (Nowak, 1993). Thus, a car driven 26,000 miles will emit between 22,880 lbs CO2 and 27,647 lbs. CO2. Thus, one acre of tree cover in Brooklyn can compensate for automobile fuel use equivalent to driving a car between 7,200 and 8,700 miles.
Um well there are big tree's and little tree's.
Specify please
I'm not sure but I know the value of its shade when heat
exhaustion is only moments away.
There are numerous factors including tree type, tree age, temperature, etc. etc.
The average is between 7.5 and 13 Kg of CO2 per year, however the tree must be older at least 15 years old to effectively absorb this. Younger trees absorb very little CO2 so for the purpose of this answer assume that they do not absorb CO2.
Basically 1 tree will absorb 1100 Kg of CO2 in its full uninterrupted lifetime.
This raises big issues with the carbon offset claims, about 10% of all tree planted will die naturally within 1 year from disease, pest, lack of nutrients/water, etc. Many other trees will be cut down by humans.
If you plated 1 tree while producing 1100Kg of CO2 a year for 100 years there would be a net gain of 52.1 Kg of CO2.
Another problem with carbon offsets are quality control, once the tree is planted its on its own, completly able to be cut down or die naturally without you knowing or the company replacing it.
If you believe in global warming fake carbon offsets are not the way to go.
some tonnes...>_< My memory doesn't do me any justice...Depends on the species though,not every kind of tree absorbs carbon dioxide,some even release it!(from what i have read)
