Businesses in aviation industry, where fierce competition has been encountered, have had to pay more attention to their relationships with the environment to increase their market share and to survive. In this context, enterprises have started to focus on corporate social responsibility (CSR) applications to provide sustainability in terms of environmental, social and economic. Although there are many academic studies on this subject in other sectors, it is relatively less in aviation sector. Therefore, in this study, CSR applications in terms of enterprises operating in Turkish airports have been analysed using GRI (Global Reporting Initiatives) scale for the airport system. Within the extent of the research, the necessary information has been obtained through the reports published by the companies, internet pages and social media accounts etc. for CSR activities. Content analysis was used to analyze the data. As a result of the research, it has been determined that the majority of enterprises do not share their CSR applications publicly enough, even if they perform most of these activities. According to the results, suggestions have been made to the airport and terminal operators to apply more effective CSR activities.
