Evergreen trees are green year round because they do not lose all of their leaves in one season. Most will however lose some of their oldest leaves just before they produce new leaves in the spring. Some will lose part of their leaves in the fall.
A tree can absorb as much as 48 pounds of carbon dioxide per year and can sequester 1 ton of carbon dioxide by the time it reaches 40 years old.
Tree leaves are composed of many colored pigments -- green chlorophyll hides them during the spring and summer growing seasons. Shorter days and cool temperatures in the fall cause the chlorophyll to break down and the other pigments to be see.
