Carbon dioxide also is released when organic matter burns (including fossil fuels like oil or gas). Carbon dioxide acts as a greenhouse gas, trapping heat in Earth’s atmosphere. WebCarbon dioxide is the primary greenhouse gas because it is emitted in large quantities, and it has a long-lasting influence because it can stay in the atmosphere for hundreds to thousands of years. Therefore, CO 2 emissions that are released today will continue to influence the climate for a long time to come. bar sizing chart
