Unified Data Highways: Enabling Responsible Data Sharing for Inclusive Digital Transformation

As data is increasingly being recognized as the backbone of the digital economy, the drive for enabling responsible data sharing to unlock ecosystem-wide innovation is gaining momentum rapidly. Unified Data Highways (UDH)—data-sharing networks built on Digital Public Infrastructure (DPI) principles—are positioned to play a pivotal role in helping emerging nations unlock the full potential of their data.

This report, developed in collaboration between the Japan International Cooperation Agency (JICA) and Boston Consulting Group (BCG), explores the evolution and transformative potential of UDH across eight key sectors in 24 countries. By enabling secure, interoperable, and scalable data sharing, UDHs are projected to generate USD 3–4 trillion annually for emerging economies by 2030, representing 5–6% of their projected GDP. The report highlights UDH as powerful catalysts for collaborative innovation and enhanced public services, while also improving the daily experiences of citizens—making activities such as multi-modal transportation and accessing healthcare services more seamless and efficient. To help nations fully realize the benefits of UDH, the report outlines 15 guiding principles spanning governance, technology, and execution. It provides strategic guidance for addressing challenges such as fostering adoption, developing sustainable business models, and maintaining strong governance over data sharing.
Ultimately, the report calls for close collaboration among governments, the private sector, and international organizations to harness the full potential of UDH—paving the way for a responsible, inclusive, and sustainable digital future.
