A method for removal of carbon dioxide (CO2) 42 from exhaust gas, in particular from a vehicle engine. Carbon dioxide from the exhaust gas is captured by a solution 20 containing at least one amine. The exhaust gas may be cooled in a cooling chamber, using a coolant 32, to a temperature of less than 100ºC, in particular to about 60ºC. At least part of the solution containing absorbed carbon dioxide may be removed from a reaction chamber 18 and heated, preferably by heat contained in the exhaust gas, to more than 100ºC to remove the carbon dioxide there from. The removed carbon dioxide may be stored in a vehicle fuel tank equipped with a moveable separator, and then used as a coolant in air conditioning, or in engine and/or exhaust cooling. The exhaust system may comprise a reservoir which contains the amine solution, and means to introduce the solution into the exhaust.
