The present invention relates to a cement composition and a method for producing same, and specifically, to a carbon dioxide storage cement composition using a carbon dioxide captured by-product and a method for producing same, wherein: a carbon dioxide captured by-product is produced by capturing carbon dioxide by reacting an exhaust gas discharged from cement production equipment with an absorbent solution in which calcium hydroxide (Ca(OH)2) and an alkaline admixture are mixed; and an additive is added to the carbon captured by-product and the resultant by-product is dried into a powdery form, and then mixed into cement to produce a carbon dioxide storage cement.
