This program book on The First Korea-MDB Green Cooperation Forum contains presentation materials on efforts, actions, and innovation in the green sector taking place in different countries. The forum was organized by the Ministry of Environment of the Republic of Korea and Korea Environmental Industry and Technology Institute (KEITI) under the theme of “Korea-Multilateral Development Bank Green Cooperation.” The three sessions of the forum served as a venue to discuss key issues in green areas and identify demand for future cooperation by sharing major outcomes achieved so far through cooperation projects between Korea and MDBs.
