The effects of the worldwide differentiated-rate carbon tax based on the imputed price of carbon (ICT) are discussed in this paper. In order to reduce CO_2 emissions cost-effectively, the world-wide uniform-rate carbon tax (UCT) is one of the best methods. However, it is unacceptable for developing countries due to the heavy economic burdens. Then, the effects of ICT and UCT are compared here. Concretely speaking, ICT and UCT imposed on either all industrial sectors or the upper sectors respectively, namely two types of ICT and two types of UCT are compared from the policy viewpoint regarding influences on CO_2 and GDP using the applied general equilibrium model. Consequently, though less CO_2 emissions are reduced in the cases of two ICT than UCT that imposed on the upper sectors (UUCT), ICT generates positive GDP effects on developing countries unlike UUCT. Considering the importance of worldwide introduction of CO_2 abating policies and avoidance of excessive economic burdens on developing countries, ICT, especially that imposed on the upper sectors, have higher fairness among regions and policy effectiveness than DUCT.
