A framework for ethical sourcing of construction materials

Abstract

Climate change and a speedily depreciating ecosystem are global challenges. These challenges are, in the main, attributed to activities in the construction industry, which relies heavily on the environment to provide materials. Studies show that the impact in developing countries is worse, due to the low level of awareness. Consequently, there is a dearth of research-based evidence on the ethics of sourcing of materials. This research aimed at changing that by investigating the ethics of materials sourcing in Nigeria. Epistemologically, the research is subjective and paradigmatically phenomenological. The methods used for data collection include a comprehensive literature review, collection of archival records, empirical studies of sixteen organisations that are involved in materials sourcing, transportation and production of eight construction materials across the six geo-political zones in Nigeria, that were purposefully selected. The findings reveal that the majority of the processes employed to source, transport and produce materials for the construction industry are not ethical environmentally due to their contribution to air pollution, water pollution, noise pollution and vibration, landscape damage, harm to flora and fauna and waste production. Furthermore, the study found that the majority of the organisations studied, do not produce sustainability reports for their operations. The study developed a framework for ethical sourcing of construction materials. The study recommends that organisations should utilise the framework developed in this study to enhance their sustainability practices
