Concrete - Energy Consumption - Green Building Central

For every ton of cement produced, approximately 2,400 pounds of carbon dioxide are released. Carbon dioxide emissions from the production of concrete stem from two primary sources: the energy used in the production of cement and the chemical process of calcining limestone into cement (CaCO3 -> CaO + CO2). Each is a major contributor (Table 2).
