<p>The climate crisis poses significant challenges to sustainability and necessitates an education that encourages environmentally responsible behaviors. This is particularly important because most of the actions that contribute to climate change are human activities. This study investigated the impact of environmental beliefs and values on pro-ecological behavior among university students in Colombia, with a focus on gender differences. A total of 186 university students participated in the study. Participants completed the Climate Change Causality Beliefs Questionnaire, the Pro-Ecological Behavior Scale, the Climate Change Scale, and the Environmental Beliefs Questionnaire. Regression analysis revealed a coherent pattern of gender-based differences in the predictors of pro-ecological behavior for men, frugality was identified as the main predictor, while for women, environmental concern and beliefs about climate change emerged as the most influential variables together, these findings show that although both genders display pro-environmental attitudes, the underlying motivations differ, reflecting distinct value orientations and beliefs. This information is valuable for designing environmental awareness and education programs, both within and outside universities. Furthermore, the study highlights practical implications for environmental education and emphasizes the need for future research with larger, more diverse, and cross-cultural samples to expand the understanding of these relationships.</p>
