It has long been recognized that education and training are essential factors in promoting environmental management in business organizations. So far, however, there has been little documentation about environmental management practice and related educational and training requirements in even leading companies. As an attempt to characterize the current status of introducing environmental management activities into pioneering business organizations and how the reaction from the equivalent educational institutions has been towards introducing this new managerial discipline in the curriculum an EU research project has been carried out. One of the basic research methodologies was a case study approach. The background for selecting this approach, how it was carried out as well as a few concentrated examples will be presented in this paper.
