WebCoal, oil, gas, cement: where do CO 2 emissions come from? Carbon dioxide emissions associated with energy and industrial production can come from a range of fuel types. … WebThe process of mining sand and gravel, crushing stone, combining the materials in a concrete plant and transporting concrete to the construction site requires very little energy and therefore only emits a relatively small amount of CO2into the atmosphere.
WebFeb 25, 2024 · The Portland Cement Association states that for every pound of cement produced, 0.9 pounds of CO2 is generated. Cement is only one ingredient in the manufacturing of concrete. Collectively, one cubic yard (about 3,900 pounds) of concrete produces roughly 400 pounds of carbon dioxide. WebIt’s possible that one of the ingredients in cement is limestone. When limestone is heated to make calcium oxide, carbon is produced. The waste product is carbon dioxide, which is released into the air. Carbon dioxide is a greenhouse gas, so it’s a good idea to store it in the form of carbonate rocks.
