A Green-Kubo formula, relating the shear viscosity to discrete time correlation functions, is derived via a Liouville equation formalism for a class of non-deterministic lattice gas models. This allows a Monte-Carlo calculation of the viscosity. Preliminary results are presented for the Frisch-Hasslacher-Pomeau two-dimensional lattice gas model.
