A large shade tree planted on the southwest side of the house can provide cooling shade in the summer, helping reduce air conditioning costs. Once the leaves drop in the fall, the winter sun is free to warm your house on cold winter days. Evergreen trees, planted to block cold winter winds, can help reduce winter heating costs. One of the greenhouse gases causing the most concern is carbon dioxide. Plants take this gas out of the air and use it in photosynthesis.
Carbon is stored in the wood and living tissues of trees.
When leaves fall and are composted, carbon is added to the soil. This improves the soil for plant growth and stores more of the carbon in the form of soil organic matter. Carbon can be stored for hundreds of years in the trunks of trees or in the form of lumber, furniture, and other wood products. By planting trees in your yard, you can help reduce greenhouse gases. Trees also provide shelter and food for a variety of wildlife.
