Issues such as climate crisis and poverty caused by human activities and the breakthroughs that include solutions have started to form the responsibilities of corporations that are a part of society as well as societies. The main concept that will enable sustainability to be internalized by the entire organization is corporate culture. In this qualitative research, in-depth interviews were conducted with a semi-structured interview form prepared using the corporate sustainability themes developed by De Grosbois (2016), which is used to measure sustainability practices, and the corporate culture dimensions of Robbins (1990), which allows the measurement of corporate culture (Robbins, 1990, p. 439 as cited in Vural, 2016, p. 60), in order to reveal the role of the two concepts on each other. According to this, it has been revealed that corporate culture supports corporate sustainability efforts, and it has been determined that educational corporations have added sustainability-related themes to their vision and missions that form their corporate culture. While studies on environmental sustainability and social contribution gain importance in schools, sustainability principles are established and conveyed to new employees through orientation and various events, in-house communication tools and social media.
