Abstract
Environmental load by tourism in Yakushima Island, registered in World Heritage Natural Property in 1993, was calculated based on field study to propose a method for sustainable tourism establishment. A questionnaire to grasp tourism behaviors and an investigation on discharged waste from facilities related to tourism were carried out. The questionnaire includes questions such as a lodging place, number of lodging days, eating place and number of times, visiting sightseeing places and so on. The investigation for discharged waste was consisted of examinations of discharged amount and number of user at the period, waste composition. From the results of the questionnaire for tourists, tourist patterns are categorized into 5. The environmental loads such as waste discharge amount and carbon dioxide emission of each tourist pattern were calculated. At the viewpoint of waste, the hotel users would discharge larger amount of waste than the users of a lodging house and a campsite. The reason is that the hotel user discharge a lot of garbage waste during their stay in the hotel. Future environmental load was estimated based on scenarios.
