We are helping Apple spread the word about the world’s greenest family of notebooks. The MacBook line is built using highly recyclable materials and these notebooks are free from many harmful substances in other computers. Additionally, the packaging has been changed to be 41 percent smaller than the previous generation, and the MacBook computers are more energy efficient through LED-backlit displays and other adjustments.
Check out this Apple Video that describes it all: MacBook Goes Green
