An introduction to the concept of a fractal-synergetic approach to the procedure for conducting the environmental audit to support decision-making in the environmental management based on the virtual reality technology is given in this article. The necessity for application of Synergetics and fractal modeling in the implementation of the expert-analytical system of the environmental audit is substantiated.
