The world is approaching the midpoint implementation of the 2030 Agenda for Sustainable Development, but only 12% of the targets are on track. Digital public infrastructure (DPI) has emerged as a critical enabler of digital transformation and can turbocharge progress to deliver on the SDGs. But to do so, it is paramount to understand where DPI has had success and where potentials exist in order to best leverage learnings and experiences on a global scale. This compendium presents a snapshot of digital solutions in action around the world that can help move the needle and get us back on track. Mapped across all 17 SDGs, the solutions include a mix of mature DPI and others that could potentially become ones, all sharing the common characteristics of interoperability, open standards, societal scale, and robust enabling rules and regulations. With a whole-of-society approach for driving DPI in mind, this compendium is designed as a first of its kind knowledge resource and guide that decision-makers and practitioners in government, international development, private sector, or civil society can use to inform their efforts towards accelerating SDGs through DPI.
