In the context of our rapidly changing climate, understanding the role of individual attitudes and behaviors in shaping environmental outcomes is paramount. This study investigates the nexus between emotional intelligence (EI) and sustainable decisions among engineering practitioners. Unlike previous studies, which primarily focused on cognitive factors, this study places EI at the forefront. Through a comprehensive literature review and an online survey, the study reveals a significant positive correlation between EI and sustainable decisions. Engineers with higher EI scores demonstrate greater empathy, adaptability, and interpersonal skills, which directly impact their decision-making processes. These emotionally intelligent practitioners exhibit proactive behavior, resourcefulness, and resilience in the face of climate change’s escalating challenges. The findings underscore the need to integrate EI training into engineering education and professional development. By enhancing emotional self-awareness, engineers can navigate complex sustainability dilemmas effectively. Policymakers, organizational leaders, and educators should recognize EI as a crucial factor in fostering adaptive coping mechanisms and promoting sustainable practices.
