What Trees Mean to Communities
In a recent blog post, NRDC’s director of sustainable communities, Kaid Benfield shares a few impressive facts about trees, via the National Arbor Day Foundation and the US Forest Service:
- The net cooling effect of a young, healthy tree is equivalent to ten room-size air conditioners operating 20 hours a day.
- If you plant a tree today on the west side of your home, in 5 years your energy bills should be 3 percent less. In 15 years the savings will be nearly 12 percent.
- One acre of forest absorbs six tons of carbon dioxide and puts out four tons of oxygen.
- A number of studies have shown that real estate agents and home buyers assign between 10 and 23 percent of the value of a residence to the trees on the property.
- Surgery patients who could see a grove of deciduous trees recuperated faster and required less pain-killing medicine than matched patients who viewed only brick walls.
- In one study, stands of trees reduced particulates by 9 to 13 percent, and the amount of dust reaching the ground was 27 to 42 percent less under a stand of trees than in an open area.
