Green Entrepreneurship as a Business Sector is a result of climate change, environmental pollution and irresponsible management of natural resources. It represents a subsystem that is part of the Croatian economy system, as it carries at the same time sustainable development, financial stability, economic profitability and the impact on population growth and the reputation of the country as a tourist country. This subsystem has opened the door to the future of rural tourism development, whose importance is reflected in the very important interaction of agricultural production with ecological standards. Ecological agriculture as a mode of production carries with it the use of ecological substances and resources without the use of harmful particles, which contributes to the traditional preservation of the soil itself and the influence on the rich fertility. The production of tropical fruit in Croatia is at its beginnings and thanks to its attractive properties it attracts an increasing number of potential investors and customers and its consumption is growing significantly both domestically and internationally. This paper describes the function of green entrepreneurship as a key factor for the development of rural tourism and its impact on the situation of rural tourism in Croatia and its importance of ecological agriculture through the example of tropical fruit growing in the Ravni Kotari region and economic viability.
