This paper discusses the emergence of climate clubs as a new form of international cooperation to address climate change and its implications for trade policy. Climate clubs are presented as a potential solution to overcome the limitations of multilateral efforts and unilateral climate-trade measures. The paper explores the concept of climate clubs, examines real-world examples like the G7 Climate Club and the Global Sustainable Steel and Aluminum Agreement, and analyzes their potential economic impacts using simulation models. It also presents findings from interviews with domestic industries in South Korea regarding their perspectives on climate clubs.
