On September 25, 2015, the world's leaders adopted a new suite of development goals—the Sustainable Development Goals (SDGs)—that are to guide policymakers for the next decade and a half. On first inspection, the declaration is breathtaking in its scope and ambition. Constituted by a list of 17 goals and 169 targets, it is arguably the most comprehensive global agenda adopted since the UN Charter in 1945. Its thematic repertoire ranges from poverty, health, education, and inequality, to energy, infrastructure, climate change, marine resources, peace, security, and good governance. The UN Secretary-General welcomed the SDGs by praising their “universal, transformative, and integrated agenda” that heralded a “historic turning point for our world.”
