This policy brief explores the urgent need to close the global education financing gap to meet SDG4 targets by 2030. With a shortfall of US$97 billion annually in low- and lower-middle-income countries, the lack of adequate public funding threatens broader development goals like poverty reduction, social stability, and climate action. The brief calls for long-term sustainable financing solutions, including increasing domestic resource mobilization, enhancing international cooperation, addressing debt distress, and further scaling innovative financing, to ensure equitable access to quality education and drive long-term socioeconomic progress.
