Single-charge tunneling in ultrasmall voltage biased superconductor-insulator-superconductor junctions in a high-impedance electromagnetic environment is considered. The Cooper-pair current is calculated at {ital T}=0 on the basis of the elementary tunnel Hamiltonian for quasiparticles where the transfer of Cooper pairs emerges automatically as an effect of higher-order perturbation theory. The frequency dispersion of the supercurrent is taken into account because it depends on the frequency-dependent pair current amplitude {ital I}{sub {ital p}}({omega}).
