detailed insight specifically into the internal barriers to ISO
14001, which is the focus of our paper. We have summarized
the findings from the literature in Table 1.
Table 1 is organised around ISO 14001 clauses and subclauses.
For each clause and subclause, a set of barriers is
listed. The rationale for this is twofold: (a) to capture the barriers
that were already identified in the literature and (b) not to
overlook any element of ISO 14001. Table 1 derives mainly
from Hillary’s [23] research that provides a comprehensive
overview of the barriers to ISO 14001, Eco-management and
audit scheme (EMAS) and BS 7750.
