摘要：Sustainable practices in Indonesia’s construction industry have been considered and implemented in green building projects, even though they are not yet enforced by specific regulations on the practices, especially for procurement processes by the contractors. It is believed that the contractors’ procurement for selecting subcontractors and suppliers could boost the implementation of sustainability in construction industry since most construction companies deliver majority of their works through their supply chains. This paper presents the comparison between the sustainable procurement principles to the Indonesian contractors’ practices in procuring subcontractors and suppliers of their supply chains to support their green building projects. By so doing, the study would measure the compliance of sustainable procurement principles and practices by the Indonesian contractors. For this purpose, the ISO 20400, which is a flexible framework for sustainable procurement were used. The study was conducted using an integrated approach of grounded theory and qualitative data analysis based on a semi-structured interview to 3 large state-owned contractors in Indonesia that have been involved in green building projects. The results show that all contractors have the same level of sustainable procurement practices where the sustainable elements in its procurement process are still in the initiation stage and there are some sustainable procurement resources already existed in the practices that could support further implementation. This study provides the first comprehensive insight into the comparison between the initial sustainable procurement practices by Indonesia’s contractors to the ISO 20400. The contribution of this study could be used by Indonesian contractors to improve their sustainable procurement practices for green building projects or other sustainable projects in the future.
