Purpose: This study aimed to identify the factors affecting the climate, health, and nursing-related perceptions and behaviors of nursing students with clinical experience. Methods: This descriptive study used a structured questionnaire to survey 3rd and 4th year nursing students from two universities, and the final data from 194 students were analyzed. Data were collected from December 5~19, 2024, using the Climate Citizenship, Climate Health Literacy, and Korean Version of the Climate, Health, and Nursing Tool. Data were analyzed using the t-test, analysis of variance (ANOVA), Pearson’s correlation coefficients, and multiple regression analysis. Results: The mean score for climate, health, and nursing-related perceptions and behaviors was 4.05 out of 5 and ranged 2~5. Multiple linear regression showed that climate, health, and nursing-related perceptions and behaviors were predicted by climate health literacy (β=.47, p<.001) and climate citizenship (β=.28, p=.001). Conclusion: It is necessary to include content that improves climate health literacy and citizenship in educational programs related to climate, health, and nursing.
