Building: Industrial manufacturing emits lots of CO2, but it only accounts for 2 percent of U.S. emissions. Iron and steel manufacturing and cement production are the biggest offenders. These industries consume monumental quantities of heat energy to convert raw materials into construction products.

Deforestation: Trees are potent organisms for absorbing and removing CO2 emissions from the air. Cutting them down stops that process. Although deforestation is a minor source of increased CO2 in the U.S., loss of forestlands account for 20 percent of global CO2 emissions. Burning trees for fuel and natural decomposition of forest material also release CO2.
