Divergence in stakeholder perception of sustainable remediation

The modern society is increasingly demanding sustainable practices in engineering fields. In the specific case of engineering practices for restoring contaminated land, there is an ongoing sustainable remediation movement which has rapidly drawn attention from both the industry and governments. It is well recognized that decision making in contaminated land remediation depends on the interaction of a variety of stakeholders. However, there is still no consensus as for how various stakeholders perceive sustainable practices in remediation, and how stakeholders interact in decision making that may lead to sustainable practices. The present study proposes a hypothetical model depicting the mediating effect of stakeholder perception in decision making. Using empirical experiences, questionnaire survey, and qualitative interview results, the present study found that there is divergent perception by various stakeholders regarding how sustainable behavior is adopted and how it is affected by stakeholder influence. The divergent view was attributed to varying organizational objectives, information access, and self-perception. Moreover, it found that incorporating sustainability into real engineering practice is transdisciplinary and requires transdisciplinary processes that can help various stakeholders to reach consensus.
