The purpose of this study is to analyze the factors influencing the climate crisis behavior of elementary, middle, and high school students in Gyeonggi-do. Specifically, it explores the mediating effects of climate crisis risk perception and ecological citizenship on students climate crisis behavior. To this end, a survey with a total of 1,173 respondents was conducted of elementary, middle, and high school students in Gyeonggi-do. Based on the response data, descriptive statistics analysis, structural equation model analysis, and multi-group model analysis were applied. As a result of the study, first, students perceptions of climate change risk and ecological citizenship were found to mediate the relationship between climate change knowledge, level of education, and climate change attitude. Second, climate change knowledge and level of education had an effect on climate change risk perception and ecological citizenship, while climate change risk perception and ecological citizenship had a positive effect on climate change attitudes. In particular, it was found that ecological citizenship was not cultivated through a specific curriculum or through such things as creative experiential activities, but through the whole curriculum. This study shows that education in the era of climate crisis should be transformed.
