An empirical study of the initial adoption of ISO 14001 in Japanese manufacturing firms

This paper analyzes stakeholders' environmental preferences/pressures and the financial flexibility that together influence firms to adopt ISO 14001, which is the international standard primarily concerned with an Environmental Management System (EMS). Since firms retain ISO 14001 once they have adopted it, a firm's decision to adopt ISO 14001 is considered from the period that they initially acquire the certification. Therefore, we assert that we have to focus on the determinants of initial ISO 14001 adoption. We analyzed: 1) the determinants of initial ISO 14001 adoptions respective to 1996, 1999, and 2004; and 2) the determinants of initial ISO 14001 adoptions during the period 1996-2004. The estimation results support the view that stakeholders' environmental preferences/pressures and firms' financial flexibility influenced their decision to adopt ISO 14001 in both analyses. Particularly, it is remarkable that we found that: 1) the determinants of the initial ISO 14001 adoption differed among the years of adoption; and 2) there is a positive relationship between economic performance and initial ISO 14001 adoption.
