A Meta-Analysis of the Intellectual Structure of Climate Change Research Published in Environmental Policy

This study examines the intellectual structure of climate change research in Korean academia, focusing on 131 climate change-related articles published in Environmental Policy for 30 years between 1995 and 2024. This study uses the analysis and visualization of word clouds and clustered network structures of keywords and authors. It explores main topics, temporal changes, and collaboration patterns. Additionally, it examines differences among various approaches to addressing climate change. The analysis identifies prominent topics such as Climate Change, Carbon, Emission, and Greenhouse Gas, while noting that Global Warming, Climate Crisis, Carbon Neutrality, and Net Zero have gained limited attention so far. It also reveals temporal shifts in research focus, with increasing diversification of topics. Collaboration patterns highlight the significant role of professors and institutional researchers, as well as active co-authorshipwith emerging scholars, including doctoral and master’s students. These findings provide a broad overview of how research topics and academic collaboration have evolved, offering insights into the intellectual landscape of climate change-related academia in Korea. By understanding these dynamics, this study lays the groundwork for future comparative analyses and deeper explorations into the field.
