The invention relates to a method for processing a gas in order to reduce the carbon dioxide content thereof, wherein the method is characterised in that it comprises contacting the gas with a compound of at least one rare earth element, whereby the carbon dioxide is adsorbed on the compound and a carbon-dioxide depleted gas is obtained. The compound may more particularly contain an oxide, and the rare earth element may particularly be selected from cerium, lanthanum or praseodymium.
