The Connection Between Environmental Management Systems and Continual Environmental Performance Improvements

This paper discusses the connection between standardized environmental management systems and environmental performance, based on a case study. By comparing the environmental reviews for a group of small and medium-sized enterprises (SMEs) before and two years after their EMS implementation, we try to show how the environmental performance of these firms has developed and draw some conclusions regarding the connection between standardized EMSs and environmental performance in general.

The case study illuminates some central aspects of ISO 14001's requirement of continual improvement. Taken together with the literature on this issue, it is clear that in practice a set of indicators are established and monitored, indicators concerning operations as well as management efforts. Hence, the selection of indicators is crucial. External environmental auditors should compare the development of these indicators and determine if an improvement has occurred or not. Naturally, this judgement by auditors is very important and difficult. The situation is very similar to the weighting step recognized as a problem in life cycle analysis, but the use of indicators for management efforts adds an additional dimension to this already intricate problem.
