Abstract: A method for generating carbon dioxide is disclosed. The method can used for efficiently separating immobilized carbon dioxide from amines, which have absorbed and immobilized the carbon dioxide, without using energy such as heat. The method for generating carbon dioxide is characterized by efficiently generating carbon dioxide at room temperature and atmospheric pressure by adding a solvent to a carbon dioxide generator which contains an optionally substituted N—C7-14 aralkyl carbamic acid or a salt thereof and/or a bicarbonate of an optionally substituted C7-14 aralkyl amine, or a hydrate of these compounds.
