Tourism in general represents one of the most important resources in the budget of many countries, on which modern approaches to sustainable development [1] depend, in particular green tourism that directs tourists to environmentally distinctive tourist sites, specifically as green tourist facilities and other landmarks that preserve the environment according to the environmental footprint on which tourism projects are built. In particular, the tourism-environment relationship should be examined from a twofold perspective: on the one hand, the environment generates tourism, as an element of attractiveness and insofar as its value and worth is recognized; on the other hand, however, the environment is used by tourism, often unaware, or disinterested, in the impacts it has. Tourism, in fact, “consumes” environmental resources locally, inevitably causing their degradation. This aspect takes on very specific connotations determined by the existence of “values” of the environment, which are even more pronounced in the case of protected areas, which are established to protect environmental values that are generally of relevance and “fragility”. Green tourism encourages the use of alternative (renewable) energies, such as solar, wind and other energies, in order to reduce climate change and its repercussions on the environment, in line with the United Nations’ efforts under the Kyoto Protocol in 2005, especially to reduce gas emissions from industrialized countries.
