This paper explores how Southeast Asia can build the legal foundations to support a “Twin Transition”: the shift toward both digital transformation and green sustainability, through Public-Private Partnerships (PPPs). Given ASEAN’s diverse legal systems, climate risks, and infrastructure gaps, PPPs are key to attracting private investment and innovation. But managing both digital and green goals in long-term contracts requires legal frameworks that are flexible, fair, and adapted to regional realities. This paper details a range of legal tools and mechanisms crucial for navigating this nexus in Southeast Asia. This includes the evolution of performance-based contracts to encompass both digital efficiency metrics and specific environmental outcomes, alongside innovative risk allocation strategies for technological obsolescence, cybersecurity, and climate-related events pertinent to the region. The paper examines the transformative potential of smart contracts and blockchain for enhancing transparency, accountability, and automated compliance in ASEAN’s digital-green projects, while also addressing their inherent vulnerabilities and regulatory challenges across diverse jurisdictions. Furthermore, it delves into the critical role of comprehensive data governance frameworks, including privacy-enhancing technologies and emerging AI governance standards, to manage the vast data generated by smart green infrastructure. Finally, it highlights the importance of fostering adaptive regulatory sandboxes for accelerating innovation, establishing robust dispute resolution mechanisms for complex, integrated projects, and leveraging existing and emerging international legal norms (e.g., cross-border data privacy rules, ASEAN digital integration frameworks) for facilitating greater regional collaboration in the Twin Transition. Ultimately, this paper advocates for a proactive, adaptive, and ethically grounded legal architecture within ASEAN that can effectively bridge the divide between digital innovation and environmental stewardship, enabling PPPs to fully realize their potential as catalysts for a truly sustainable, technologically advanced, and resilient future across Southeast Asia.
