Sustainability is a complex concept that is addressed by most companies, and is the direction of their development. Culture and education for sustainable development must start from higher education. At the level of higher education, the presence of sustainability subjects was mainly assessed in the curricula of study and also the understanding of the concept among students. In Romania these studies are not defined in depth. Also a comparative analysis of students' knowledge and understanding of the concept in business (after graduating higher education) has yet to be made. The purpose of this paper is to highlight the current level of education for students and the business environment based on the sustainability principles. The first objective of this paper was to review and present the previous research on Education for Sustainable Development (ESD). The second objective was to identify and assess the current level of ESD in Romania.
