This study examines the integration of blockchain technology in public–private partnership (PPP) projects, with a focus on enhancing transparency and accountability in environmental, social, and governance (ESG) risk management. PPPs play a crucial role in global infrastructure development, addressing economic and societal needs by leveraging collaborations between public and private sectors. However, managing ESG risks in these projects presents significant challenges, particularly in terms of transparency and accountability due to the complex, multi-stakeholder nature of PPPs and the lack of standardized reporting frameworks. Blockchain technology, characterized by its decentralization, immutability, and transparency, emerges as a transformative solution to these challenges. By providing a secure and transparent platform for real-time data access and ESG performance tracking, blockchain can significantly improve stakeholder engagement, enhance governance practices, and align PPP projects with global sustainability goals. The paper proposes a blockchain-based framework to standardize and manage ESG considerations in PPPs, utilizing a decentralized application (DApp) built on Hyperledger Fabric. This approach aims to revolutionize the management of ESG risks in PPPs, fostering more sustainable and equitable development outcomes. The efficacy of this framework will be evaluated through a conceptual case study, illustrating its potential to streamline ESG risk management and enhance the overall accountability and transparency of PPP projects.
