Environment protection, like a new religion consists of: environmental programmes, objectives and targets, training, incentive schemes, audit frequency, site inspections, administration and community relations. This paper presents the main environmental performance indicators. They should therefore be cost-effective and appropriate to the size and type of organization and its needs and priorities. Organizations should make the optimum use of the environmental information they collect. To this end the indicators should fulfill the dual purpose of assisting the management of the organization and providing information to stakeholders. In article we present a set of Environmental Performance Indicators (EPI). These indicators should therefore be cost-effective and appropriate to the size and type of organization and its needs and priorities. We present many categories of environmental performance indicators: comparability (indicators should enable a comparison and show changes in the environmental performance); balance between problematic (bad) and prospective (good) areas, continuity (indicators should be based on the same criteria and should be taken over comparable time sections or units); timeliness (indicators should be updated frequently enough to allow action to be taken); clarity (indicators should be clear and understandable).
