Abstract: A carbon asset risk management method is carried out by a calculation device for selecting a target carbon emission allowance increasing means from a plurality of carbon emission allowance increasing means candidates according to a first property and a second property of each means candidate. The carbon asset risk management method includes following steps: (a) selecting at least a first means candidate from a plurality of carbon emission allowance increasing means candidates, the first property of each selected first selection being identical; (b) selecting a first means candidate as the target carbon emission allowance increasing means from the selected first means candidates; and (c) repeatedly carrying out step (a) and step (b) until a predetermined finish condition is met. Therefore, a high efficient carbon asset risk management solution is achieved.
