The challenges created by global competition make it imperative for enterprises to continually rationalize and improve all resources and processes.

On the base of literature review, we assert that recent achievements proved that ISO's management system standards have a global relevance of and a capacity to benefit from the very largest to the very smallest organizations in both public and private sectors. An Environmental Management System (EMS) provides a solid framework for meeting environmental challenges and realizing the above benefits.

From the early 1990s, a more integrated approach has been taken across all media with Integrated Pollution Control (IPC) and, more recently, the Integrated Pollution Prevention and Control (IPPC) European Directive.

In conclusion we analyse the future key areas the environmental legislation is likely to be developed in
