基于北美管理者的调查数据，研究正式但未认证的环境管理体系与经过认证的体系对企业绩效和环境绩效的不同影响，发现认证体系能带来更大的正面效果。
Abstract There has been an increase in interest towards corporate activities aimed at reducing or eliminating the waste created during the production, use and/or disposal of the firm’s products. Prior research has focused on the need for such activities, while current research tries to identify those components that encourage or discourage such activities. As a result of the introduction of ISO 14001, attention has turned to corporate environmental management systems (EMS). The underlying assumption is that such a system is critical to a firm’s ability to reduce waste and pollution while simultaneously improving overall performance. This study evaluates this assumption. Drawing on data provided by a survey of North American managers, their attitudes toward EMS and ISO 14001, this study assesses the relative effects of having a formal but uncertified EMS compared to having a formal, certified system. The results strongly demonstrate that firms in possession of a formal EMS perceive impacts well beyond pollution abatement and see a critical positive impact on many dimensions of operations performance. The results also show that firms having gone through EMS certification experience a greater impact on performance than do firms that have not certified their EMS. Additionally, experience with these systems over time has a greater impact on the selection and use of environmental options. These results demonstrate the need for further investigation into EMS, the environmental options a firm chooses, and the direct and indirect relationships between these systems and performance.
