Various embodiments disclosed relate to carbon dioxide-viscosifiable compositions for subterranean treatment. In various embodiments, the present invention provides a method of treating a subterranean formation. The method includes placing in a subterranean formation an aqueous composition including a compound including at least one secondary or tertiary amine group. The method also includes bubbling a gas including CO2 through the aqueous composition sufficient to protonate or carboxylate the amine group and increase the viscosity of the aqueous composition.
