Trees are important in helping to save energy by providing shade in urban environments, as they can lower temperatures in cities. According the to EPA, the shade from trees, in combination with the water vapor they release, can reduce peak temperatures by as much as 20–45°F (11–25°C) compared to unshaded areas.

And when shade is cast onto an office building or home, internal temperatures can drop 8–10°F. Some estimates say the shade from a single tree can save the same amount of energy it takes to power 10 room-sized air conditioners for 20 hours a day!

And a tree's energy saving abilities don't stop during the winter. Trees provide important windbreaks around buildings to reduce heat loss by as much as 50%, lowering heating costs and energy consumption — and saving you money!

This reduction in energy goes a long way when it comes to shrinking your carbon footprint, because over 1/3 of U.S. carbon emissions are caused by the production of electricity.

Helping to reduce and offset carbon emissions is only one aspect of how trees help improve our lives. Some of the other benefits of trees are:

• Trees can absorb and retain water. As rainwater falls, much of it gets picked up by trees, preventing it from overwhelming storm drains. On average, a mature tree in a city can absorb up to 1,000 gallons of rainfall every year that would otherwise need to be pumped and filtered. In New York City, urban trees help retain nearly 900 million gallons of rainwater annually, saving the city more than $35 million dollars in stormwater management costs.
• Trees also provide social and economic, such as creating jobs and helping to raise people out of poverty and achieve sustainable development, which ultimately improves our environment.
• Trees also provide health benefits, providing medicine and helping clean air.
