Green economy is an economy that results in improved human well-being and social equity, while significantly reducing environmental risks and ecological scarcities. It can be seen as a means to achieve a resilient economy that provides a better quality of life for all within the ecological limits of the planet. Tourism in the green economy refers to tourism activities that can be maintained, or sustained, indefinitely in their social, economic, cultural, and environmental contexts: “sustainable tourism”. Sustainable tourism is tourism that takes full account of current and future economic, social and environmental impacts, addressing the needs of visitors, the industry, the environment and host communities. It is not a special form of tourism; rather, all forms of tourism may strive to be more sustainable (UNEP, UNWTO 2005). Sustainable tourism development guidelines and management practices are applicable to all forms of tourism in all types of destinations, including mass tourism and the various niche tourism segments. Sustainability principles refer to the environmental, economic and socio-cultural aspects of tourism development, and a suitable balance must be established between these three dimensions to guarantee its long-term sustainability.
