The tunnelling of single electrons in small-capacitance normal tunnel junctions has been shown to be influenced by the fluctuations of the electrodynamic environment. We study the effect of an external circuit with arbitrary impedance on the tunnelling of quasi-particles in voltage-driven Josephson junctions and find even more dramatic effects than in normal junctions. We also discuss the influence of the environment on the tunnelling of Cooper pairs at finite temperatures.
