This article introduces Korea's Five Year Green Growth Plan (FYGGP) as the national policy portfolio framework, assesses the weakness of FYGGP using the Adaptation Policy Framework (APF)'s principals, and proposes three ideas to improve FYGGP. The first idea is setting up the Total Management System for Climate Changes (TMSCC) that consists of an effective integration process with existing authorities and plans; strong institutional support; monitoring and evaluation processes; and responsive adjusting mechanisms. The second idea is effectively applying the inventory of TMSCC to decide and modify the national policy. The TMSCC needs an independent agent under the Korean Presidential Committee which can coordinate and manage it, so that sustainability indicators and standards of judgment for mitigation can be developed and announced. The final idea is taking a systematic evaluation that can upgrade the TMSCC, linked with policy directions, as a suitability evaluation about TMSCC itself needs a process making the system; an efficiency evaluation needs a process modifying the system and a process applying policy scenarios; an accuracy evaluation needs a process forecasting policy effects and climate change impacts. This evaluation cycle can help achieve the national objectives.
