Five Lessons From a Decade of Sustainable Development Goals Policy Traction
ABSTRACT As the 2030 Sustainable Development Agenda deadline looms, the gap between political commitments and operational outcomes is widening. While previous studies offer fragmented diagnoses, holistic lessons derived from a decade of the Sustainable Development Goals (SDGs) implementation remain lacking. To address this gap, we examine 60 countries'
