Adopting Ecolabels in the Construction Industry via Blockchain

Green procurement has been a growing area of interest in public sector purchasing. The above has sparked an interest in ecolabels that provide verified environmental performance information. Green procurement and ecolabels are less observed in the construction sector due to data challenges, transparency, and implementation resources. Blockchain is a promising technology that can aid in ecolabel data verification. Combined with Building Information Modeling (BIM), blockchain can be used to ensure the authenticity of construction project data and the validity of sustainability claims. A comprehensive literature reviewhas revealed that no previous research has used BIM nor blockchain for green procurement in the construction sector. This paper proposes a methodological framework for integrating entrusted ecolabels through blockchain for the green procurement of water supply infrastructure. BIM was used as the platform for integrating project data. The outcomes of this study will improve the transparency of green procurement while promoting cutting-edge technology in the construction sector. More importantly, the outcomes of this research support addressing data credibility and accuracy in eco-conscious decision-making.
