The goal of every company is to achieve a competitive advantage in an increasingly turbulent environment. However, the question arises, how can this be achieved? Possible ways are introduction of green IT, employment of "green workers", as well as orientation towards socially responsible business. In this way, it is possible to realize a number of benefits, such as creating and maintaining a positive image and reputation of the organization, a positive influence on the attraction, motivation and retention of professional staff, which results in a reduction in the level of turnover and unjustified absences of workers. Then a reduction in business costs, an increase income due to growth in sales and/or market participation, as well as risk reduction associated with social responsibility. In addition to the theoretical part of the work, which is supported by diverse and relevant domestic and foreign literature, this work also includes a case study in which the strategic approach to sustainability and socially responsible business is analyzed on the example of the company HEP, which showed how it is possible to protect health people and the environment and thereby stand out as a company that pays great attention to ethics.
