Purpose - This study seeks to explore the roles of organizational
support and environmental manager commitment on organizational
environmental management practices. Design/methodology/approach - A
survey of environmental managers was conducted to examine the role of
organizational support and individual environmental commitment on key
informant perceptions of environmental organizational practices
including participation in extra-organizational voluntary environmental
programs, adoption of a company-specific environmental management system
(EMS), and involvement in ISO 14000 certification. Findings - Study
findings demonstrate that high perceptions of organizational support for
the environment affect the likelihood of an organization's
implementation of environmental practices. Similarly, study findings
indicate that higher levels of environmental commitment of the
individual responsible for environmental management practices affects
the likelihood of an organization's implementation of environmental
practices. Lastly, the statistical results provide evidence that high
organizational support and high personal commitment by an environmental
champion interact to enhance the implementation of environmental
practices. Originality/value - This study represents the first
development and empirical testing of a model of how organizational
support for environmental practices and environmental managers'
commitment to such endeavors affect the adoption of environmental
practices by organizations. Additionally, the research illustrates how
theoretical perspectives from the organizational behavior literature can
be fruitfully adopted to explain behavior in the field of supply chain
management.
