According to the IPCC WGII Fourth Assessment Report, more than 89% of observational data series and studies are consistent with the greenhouse gas change, which is produced from human activities, as a response to global warming. In the previous point, the tourism and leisure industry is regarding as the non-smokestack industry. However, with an increase of leisure and tourism activities, the carbon dioxide emission and energy use have been growing. Recognizing these risks, the Agenda 21 for the Tourism and Travel Industry promulgated by the World Travel and Tourism Council, the WTO and the Earth Council addressed energy consumption as a key issue of concern. The buildings are a major part of the leisure industry. Therefore, this work aims to investigate the energy use and carbon emission of a hotel building, located in the middle of Taiwan, for four seasons. The consumption generated from each visitor activating in the building also were conducted. The results will be used as a reference for further investigations into the reduction of energy use and carbon emission in the leisure buildings. By investigation of proposed carbon neutral model, the willing price to pay is highly larger than both of the shifted and non-shifted prices. Most people has always inclined to pay for self-related GHG emission. Green development and sustainable operations in the leisure industry should be attended because the real costs of a green building are less than you think.
