Relationships between stakeholder influences and the effectiveness of environmental management practices are examined using a sample of 130 diesel fleet operations within Hong Kong Special Administrative Region of China (HKSAR) companies. The results indicate that fleet managers in the HKSAR have adopted numerous elements of environmental management systems (e.g., environmental policies, planning methods, and implementation practices), but these have yet to be formally systematized. The influence of stakeholder groups on the adoption of more effective environmental management practices was found to be modest in the sample of fleets and appears to be limited to influences from community and media pressures. Fleet size, however, was shown to significantly moderate these relationships. For larger fleets, competitive and governmental pressures also emerge as significant predictors of environmental management practices
