    Sustainability is the processes related to action plans to take the necessary measures to ensure that natural resources are not damaged or depleted during consumption and that they can serve not only current generations but also future generations. As such, sustainability involves more than action plans for the protection of nature. In addition to its environmental dimension, it also has economic and social dimensions. Sustainability should be designed in a way to ensure human structures, the natural environment and economic continuity. Awareness has been raised through many studies at the level of public and non-governmental organizations around the world that sustainability is a global solution. The most important actors in creating this awareness are international organizations, governments and businesses operating on a global scale. Especially problems such as ecological degradation and destruction of natural resources caused by business activities need to be solved urgently. In this study, the concept of sustainability, socio-ecological and green organizational culture approaches are discussed and the economic consequences of these approaches are evaluated. In today's world where environmental problems are increasing day by day, this thesis provides content on environmental, sociological and economic problems and their solutions. In the study, the data of the enterprises that are included in the 5 highest volume stock exchanges in Europe and Borsa Istanbul benchmark indices and prepare sustainability reports according to Global Reporting Initiative (GRI) standards are used. In the analysis conducted with the event study method, it is examined whether sustainability reports have an impact on stock prices in the short term by generating abnormal returns. In addition, the validity of the related results is verified by panel data analysis method by including macroeconomic factors such as index movements, stock closing prices, exchange rate movements, interest rates and inflation rates in the analysis. According to the results of the analysis, significant relationships between abnormal returns and market capitalization on an entity basis are rarely observed, and it is understood that there are differences in abnormal returns by country. The short-term abnormal returns at the date of the disclosure of sustainability reports differed across countries. Considering the CAAR (cumulative average abnormal return) ratios of companies in the German stock market, short-term abnormal returns were observed at the time of the disclosure of the reports and more than half of the companies included in this sample had a significant relationship between the stock and the report on an entity basis. It is concluded that sustainability reports do not have a significant impact on stock prices in the short term in the French, UK, Italian, Swiss and Turkish stock markets.
