In the innovative research area of the psychology of sustainability and sustainable development, Intrapreneurial Self-Capital (ISC) constitutes a promising core of resources to face the challenges of the 21st century. This article presents two studies supporting the contribution of trait emotional intelligence to ISC beyond that explained by the three most quoted personality trait models. The Intrapreneurial Self-Capital Scale (ISCS), Trait Emotional Intelligence Questionnaire Short Form (TEIQue-SF), Big Five Questionnaire (BFQ), Mini International Personality Item Pool Scale (Mini-IPIP), HEXACO-60, and Eysenck Personality Questionnaire Revised Short Form (EPQ-RS) were administered to 210 first and second year university students (Study 1) and 206 university students in the last three years of undergraduate university studies (Study 2). Hierarchical regression analyses demonstrated that Emotional Intelligence (EI) explained additional variance in ISC beyond that accounted for each of the three personality trait models for both samples. These results should encourage future research within a positive primary prevention perspective in the framework of the psychology of sustainability and sustainable development.
