The first step in implementing an organization's environmental management system is the initial environmental inspection. In the course of this, the environmental performance of the organisation and its level are assessed. The main roles and contact persons, the registered office(s) of the organisation and the scope of the registration must also be defined. The commitment of the management must also be ensured.

In addition, the direct and indirect environmental aspects arising from operations and services must be identified and their impact on the environment assessed. The information collected during the environmental review (in particular, an overview of the most important environmental aspects) is the basis for the implementation of EMAS.
