Enhancing Sustainability in Food Supply Chain: A Blockchain-Based Sustainability Information Management and Reporting System

Global concern over the sustainability impacts of food products has grown considerably in recent years, driven by heightened awareness of environmental issues and the rising demand for sustainably produced foods. In response, industries are increasingly offering sustainable product options and utilizing ecolabels to communicate environmental and social impacts. While product labelling has become one of the most widely adopted tools for conveying sustainability information, existing ecolabeling approaches often face challenges of trust, transparency, and consistency. Current ecolabels are typically issued by supply-chain stakeholders or independent third-party certifiers; however, limitations in accountability and verification hinder consumer confidence. To address these challenges, this study proposes a Blockchain-based Sustainability Information Management and Reporting (BSIMR) model that integrates blockchain technology with sustainability indicators. The framework is designed to provide a standardized, transparent, and reliable approach for managing and verifying sustainability claims across food supply chains. By enhancing traceability, accountability, and consistency in sustainability auditing, the BSIMR model aims to empower consumers with trustworthy information and support industries in meeting sustainability commitments. The feasibility and applicability of the proposed framework are demonstrated through a proof-of-concept case study on sustainability information management in the rice supply chain.
