The purpose of study is to derive suggestions for Korean climate change human resource development policy by analyzing British climate change strengthening policy and expert core competence analysis. For this reason, we have analyzed in detail the core competence of climate change experts formally defined by the Department for International Development, UK International Development Division (DFID). Through the contents of "Capacity of the core group of climate and the environment" and eligibility requirements and evaluation of "Climate and Environment Advisory Committee," these significant capabilities and other capabilities, the core of UK's climate change experts we analyzed the framework of competence. South Korea also established related policies and programs and graduate schools to systematically train human resources who will lead full cooperation with developing countries with the expansion of the climate industry under regime and revitalization of climate technology mechanism. However, at the moment, the core competence of climate change talent has not been defined. By analogy through the curriculum, environmental division announcement, etc., so far, only graduate schools have been established and operated as a passage of human resources production through a general degree course. The core competence of national R&D institution climate change officers and technology transfer officials is defined, and it will be necessary to strengthen the specific capacity of the dimension through the re-education program. The concept of competence strengthening has been historically established in the UNFCCC, and the UNDP (United Nations Development Program) has developed a capacity development framework. However, the results of such efforts are introduced in the agenda form of the international community and are only utilized by some organizations and countries. The UK has enacted the 2008 Climate Change Act and has been steadily defining and analyzing the core competence of climate change experts since 2011. South Korea, like the UK, needs to regulate the core competence of experts in climate change and summarize the essential requirements of experts. These efforts are to match the supply and demand of climate change talents and to support human resource development with actual necessary skills at the site.
