A review of the literature of environmental management systems has shown a steady development of theory supporting the production of well supported environmental management systems integrated to enterprise information systems. Research into the differences between Australian Chief Financial Officers and Information Systems Managers has shown that there is a gap between company policy on environmental management systems and existing information support for them. This paper reports on the research covering Australia's top 150 companies and preliminary results of interviews of responsible officers. A model is presented which draws on the literature and research findings. This model brings a systems focus to the problem of integrating information systems with environmental management systems so as to achieve organisational goals.
