Increasing population, developing technology and growth of cities cause pollution of resources and environment. This pollution caused by mankind and the destruction it creates in nature puts nature on an irreversible path. When humanity realized this pollution and destruction, they put forward the concept of nature protection and sustainability. National parks emerged with the emergence of this conservation idea. The first national park is known as Yellowstone National Park. In our country, the Forest Law No. 6831 entered into force in 1956 with the 25th article has found a legal application area. National parks are regions where there are rare natural beauties that must be protected for the world and our country. National parks are areas where sustainability is at the forefront. Therefore, transportation to national parks and transportation within the park should be sustainable, environmentally friendly and sensitive. The use of fossil fueled carbon-based fuel vehicles increases emissions and carbon footprints from such sensitive areas and harms the environment. Therefore alternative transportation systems should be used in such sensitive areas. Pedestrian and bicycle transportation systems are the healthiest and the lowest cost of alternative transportation systems. Infrastructure costs and investment costs are low, and because of the benefits for human health are shown as the preferred mode of transport. The aim of this study is to investigate the carbon footprint of environmentally friendly transportation systems bicycle and pedestrian transportation in Beyşehir and Kızıldağ National Parks.
