The hospitality sector has undergone rapid growth in China;however,it is challenged by high energy-consumption and environmental protection. To achieve energy-saving and emission reduction,comprehensive energy consumption of the hospitality should be assessed,but research on this topic is still lagging. According to hospitality characteristics and the international general method recommended by the Intergovernmental Panel on Climate Change,the decomposition analysis method was used here to construct a comprehensive energy consumption and carbon emission evaluation model for hospitality in Shanghai over five years. We found that the annual energy consumption of our focal five-star hotel has reduced by 4% in the last five years. The comparable comprehensive energy consumption per building area of the high-star hotel can be reduced to no more than 55 kgce/m~2·a,which is an advanced level. The comparable comprehensive energy consumption per building area for two-star and three-star hotels,built more than 10 years ago,is as high as 53 kgce/m~2·a,greater than the qualified value. There are huge numbers of hotels of this class in China and they represent a potential area for energy-saving and emission reduction. Electricity is the deciding factor for indirect carbon emissions. Air-conditioning and ventilation accounts consumed the most energy in hotels. This research establishes a clear method for hospitality to reduce energy consumption and carbon emissions and provides a foundation for carbon trading in the hospitality industry.
