We aim at providing an overview of Korea’s progress in integrating climate change into its development cooperation to share the experiences and to highlight some achievements. In doing so, we first review how other developed countries have promoted climate change integration. Through comparison with Germany, the United States, and Switzerland, we summarized several achievements made by Korea in the area of development cooperation. In addition, we identified areas for further improvement to better integrate climate change into development cooperation, as well as projections for the next phase of Korea’s development cooperation to begin in 2021.
