This work has some limitations. First, social desirability bias has
become a concern in sustainability studies, as the respondents try
to perform as they believe interviewers expect. Under this
circumstance, less accurate responses can be obtained (Roxas and
Lindsay, 2012). Furthermore, this work was only related to the
Brazilian context, and only focused on ISO 14001-certified firms.
Finally, this study's research sample did not represent the distribution
of ISO 14001 sectors and firms across Brazil. Future research
should consider the effect of the industrial sector (as a control
variable) and other complex characteristics of GSCM implementation,
such as GSCM governance.
