Sustainable activities in Croatian marinas - towards the "green port" concept

Due to the intensity of marina activities and global climate change, marinas are facing the challenge of sustainability. Therefore, the concept of "green port" has now become a requirement. In practice, the term "green port" describes the activities of all stakeholders involved in the port business towards a sustainable development of the port. This paper aims to provide an insight into the current application of sustainability principles and the concept of "green port" in Croatian marinas. Therefore, the concept of "green port" is described. Furthermore, the framework (regulations, policies, international and national certificates and programs) for sustainable activities in Croatian marinas are analyzed. The main part of the paper is the analysis of sustainable activities, i.e. practices in Croatian marinas related to eco-spatial design, standardization and awarding system, energy transition, sustainable waste, water and air systems. Therefore, positive sustainable practices in selected Croatian marinas and aspects that need improvement are identified.
