Environmental information systems based on enterprise resource planning

This paper describes the consequences of the integration of environmental information within enterprise resource planning (ERP) systems. The state‐of‐the art of dedicated environmental information systems is briefly discussed. Essentials and peculiarities of environmental information are highlighted. The role of environmental management systems and their relationship with other dedicated management systems is positioned within this field. The need for information following from this is compared with the information available in current ERP systems. The common features of both information systems are discussed and the importance of physical relationships within them is demonstrated. A physical approach is argued as the very base of future extended ERP systems. An outline of the special character of physical information is presented for this purpose. Subsequently, some restrictions connected to the current approach in ERP are analysed. This results in a number of recommendations. The most crucial aspects are the integration of the process and discrete manufacturing orientation by applying a multiple‐input multiple‐output approach to all processes, and a similar consideration of co‐products, by‐products, wastes and emissions.
