The United Nations adopted the Sustainable Development Goals (SDGs) as part of the 2030 Agenda by the General Assembly on its seventieth session held in September 2015. The implementation of 17 goals and 169 targets requires whole-of-government approaches because the targets of indicators are integrated and inter-connected. The K-SDGs for ensuring sustainability were confirmed after deliberations at the Cabinet Meeting on December 24, 2018. They have been a milestone that Korea has set to be achieved by 2030 in all government sectors across the economy, society and the environment. In addition, the international community is in urgent need of an effective, inclusive and reliable promotion system to address the challenges facing the Korean Peninsula. These developments point to the need to actively consider establishing the SDGs for integration through inter-Korean cooperation.
