Energy gain and carbon dioxide(CO_2)emission of tokamak fusion power reactors; a conventional physics performance ITER-like reactor based upon ITER(International Thermonuclear Experimental Reactor)and an advanced physics RS reactor using reversed shear safety-factor/plasma current profile are evaluated in this study. Input energy to and CO_2 emission from these reactors are basically calculated by multiplying weight of fusion reactor components and materials with data of energy intensities and/or CO_2 intensities, which are updated as much as possible to suit for those reactors. Results indicated that(1)the RS reactor can reduce the input energy and the CO_2 emission half of those of the ITER-like reactor, (2)silicon carbide(SiC)used for structural material of inner vessel components is best for the energy gain and CO_2 emission reduction, and(3)less energy gain and greater CO_2 emission than a fission reactor and a water-power generation is estimated in the case of the ITER-like reactor, however, as nearly the same energy gain and CO_2 emission as can be attained in the case of the RS reactor.
