This thesis analyzes socially responsible behavior in the business of a modern enterprise from the aspect of increasing conviction that such companies have an increasing role and responsibility in society. On example of our largest shipowner "Jadrolinija" it was explored if it would be possible to profit through the application of legal and ethical behavior and the strength of moral rules. The company seeks to implement the basic principles of business ethics in the company through the ethics code. Perception, opinions and attitudes of respondents on socially responsible behavior, its application in the company itself as well as the problems and challenges in Croatia were explored while analyzing the company’s internal documentation and performing an interview. Through its projects, Jadrolinija shows a high level of social responsibility, above all through responsibility towards its employees, ethical behavior in the field of ecology, security, health and education. Theoretical and practical aspects of application of business ethics have been discussed by explaining basic concepts and their practical application. From the aspect of European policy, the CSR concept is defined as the voluntary integration of socially responsible business, including social issues and environmental protection, relationships with owners, shareholders, employees, consumers, suppliers, governments, media and the general public. An important tool to promote CSR is the method of ranking the company according to the success of its application i.e. Social Responsibility Indexes. Based on S.R.I., the best ranking Croatian companies are given awards. The same ethics ensures a better functioning of human communities. By applying business ethics, a good corporate image is created and that helps ensuring companies existence. Key to success is not separating profitability from ethics but making profit while promoting business ethics.
