This study combines issues related to the
environment (green issues) with business aspects
(supply chain). Therefore, the appropriate person
to get the required data from should ideally have
knowledge about the two aspects. Certification
organizations usually appoint an Environmental
Management Representative (EMR) in each firm to
act as a link between the certification organization
and the certified firm. The EMR can belong to any
department in the certified firm but mainly comes
from operations, quality control, and environmental
health and safety departments. The EMR keeps all
the documents regarding green issues in his firm
and makes regular updating to the certification
organization about progress in environmental
performance in his firm. Because this person is
expected to be highly informative about green issues
in his firm, in addition to his knowledge about the
business issues, this person is considered to be the
most appropriate respondent. Therefore, the
questionnaires were addressed to the EMR in each
firm.
