Emissions from the Cement Industry – State of the Planet
The direct emissions of cement occur through a chemical process called calcination. Calcination occurs when limestone, which is made of calcium carbonate, is heated, breaking down into calcium oxide and CO 2. This process accounts for ~50 percent of all emissions from cement production.

Calculating CO Emissions from the Production of Lime
Calcination is the process by which limestone, which is mostly calcium carbonate (CaCO 3) is heated in a kiln to produce quick lime (CaO). Carbon dioxide is a byproduct of this reaction and is usually emitted to the atmosphere. However, some facilities recover a portion of the emissions- e.g. for use in sugar
