As the climate crisis becomes increasingly urgent, discussions on the content and behavioral variables of climate change education are becoming more active. In environmental education, efforts are continuing to develop the ability to look far into the future with the aim of fostering ecological citizenship. However, research and educational attempts to deal with the subjective perception of future time as a major variable of behavior are insufficient. Therefore, this study attempts to analyze whether children’s future time perspective affects their behavioral intentions to address climate change. To address this issue, three studies were conducted to survey elementary school students in Korea. We found that stimuli to feel close to the future helped students expand their time horizon. Our results suggest that future time perspective is crucial in environmental education and is the key to overcoming long time lags of climate change and improving children’s futures literacy.
