THE HOME IS THE FASTEST AND BEST PLACE TO OFFSET CARBON EMISSIONS, URBAN FORESTS ARE MORE EFFICIENT THAN OTHER FORESTS ON THE OTHER SIDE OF THE WORLD...

• Trees use CO2 from the atmosphere during photosynthesis to form carbohydrates that help structure and function within the trees or plants. The plant/tree then returns oxygen back into the atmosphere as a byproduct.
• Trees also decrease greenhouse effects by shading our homes and businesses.  The shade reduces the amount of air conditioning needed to cool down the interior of these buildings by around 30% and so reducing the need for electricity made by fossil fuels and carbon emissions.
• Trees remove CO2 from the atmosphere, storing it in their trunks, branches, leaves, fruit, and roots as cellulose.  The byproduct of storing this CO2 gas is oxygen, cutting down on carbon emissions. (11)
• One tree that shades your home or office is more efficient in saving fossil fuels and carbon emissions, than 15 trees in the forest. (16)
•  Urban forests make up tree formations in every city in the world. The U.S. Urban Forest stores 800 million tons of carbon and $22 billion worth of control expenses. (1)
• When it comes to resolving carbon and other gaseous emissions planting trees is the cheapest processes to pull carbon from the atmosphere. (15)
• A single mature tree can absorb CO2 at a rate of 48 lbs./year (depending on the type of tree).  It also releases enough oxygen back into the atmosphere to support 2 humans. (10)
• An average healthy tree in the U.S. stores about 13 pounds of CO2 each year or 2.6 tons per acre of trees each year. ½ acre of trees absorbs enough CO2 over one year to equal one car driving 13,000 miles. (8)
• If every family in the United States planted one tree.  We would reduce the CO2 of the atmosphere by one billion lbs annually. This is almost 5% of the amount that human activity produces into the atmosphere each year. (17)
• The U.S. Forest Service estimates that the forests in the United States consumers/stores a net of 309 million tons of carbon per year. This is an offset of about 25% of U.S. human-caused emissions of carbon during each year between 1952 and 1992. 
• Over the life-time of a tree, about 50 years, a tree produces $31,250 worth of oxygen, $62,000 worth of air pollution control, recycles $37,500 worth of water, and prevents $31250 worth of soil erosion. (2)
• 1 Urban Forest Tree shading your house can equal an offset of as much as 15 trees in a forest. Each tree offsets about 48 lb of carbon a year.  1 Urban Tree, times (equal to) 15 forest trees, times (each tree produces) 48 lbs of carbon a year. So one Urban Forest Tree can help offset 720 lbs of CO2.
• An average single person in the U.S. produces 19.037 tons of CO2 (38,500 lbs.) each year. So there is a need to plant 54 trees per person in the United States who does not desire to conserve first. For someone who conserves, they average a production of 7.9 tons of CO2 each year, that person needs to plant 22 Urban Trees to break even for life.  Those 22 trees then produce enough carbon offsets each year to sustain that one person the rest of his life. A household of 4 would need to produce 88 Urban Forest Trees to offset their lifestyle for the lifetime of a tree or 50+ years.
