The growing popularity of sustainable tourism, which is becoming an increasingly important global topic due to increased awareness of environmental issues and the need for environmental preservation, has led to the exploration of environmentally responsible human resource management in the hotel industry of the Republic of Croatia. This paper explores whether green human resource management is present in the hotel industry of the Republic of Croatia, and to what extent Croatian tourism entrepreneurs pay attention to it. The paper includes a review of the terms environmental responsibility and sustainability in the tourism industry, with emphasis on the development of environmentally responsible practices. Special emphasis is placed on methods and the implementation of green human resource management and its effects on creating a green organizational culture and developing green skills among its stakeholders. In the empirical section of the thesis, a study was conducted on a convenience sample of 101 hotel employees in Croatia using a survey questionnaire. The research took place between June and August 2024 via a Google form, with the questionnaire distributed to participants by email. The survey featured closed-ended questions with a Likert scale to assess respondents' agreement with statements on environmentally responsible human resource management, alongside additional open-ended questions designed to explore these practices in greater depth. The research results indicate that green human resource management is present in the Croatian hotel industry but remains underdeveloped, with significant obstacles in implementation and encouraging ecological innovation among employees. While there is potential to increase employee satisfaction through ecological practices, the impact is currently limited and requires further efforts.
