Purpose: This paper aims to emphasize how economics courses offered at higher education institutions can influence sustainable development, in general, and Romania's sustainable development, in particular. Design/methodology/approach: The conclusions are based on a pilot questionnaire conducted by the authors on the level of Romanian students enrolled in public and private economic faculties. The results were based on a sample of 1,250 respondents -- students, master and PhD -- from the economic faculties of some prestigious Romanian universities. To identify differences between some groups, "t"-test analysis and ANOVA were conducted. Findings: Education is an important pillar for ensuring sustainable development because through education, people understand and learn how to become more responsible toward the environment. Studies conducted in the twenty-first century are showing a direct link between the investment in education and economic, social and human development. The present study revealed that the economic higher education system in Romania has started with small steps to adapt to the environmental requirements. Unfortunately, the efforts still required to be made are significant, since it is observed that all undergraduate, postgraduate and PhD require a change of attitude and mentality. Romanian public universities are more involved than private universities in the implementation of programs, projects, debates and courses on sustainable development and students' reactions are positive. Originality/value: This paper provides useful insights, allowing a better understanding of the role of universities in fostering sustainable development. This research is useful to find solutions for developing education for sustainable development in Romania and it can be a starting point for ESD programs and policies.
