Abstract
Hotels emit large amounts of CO2 when providing services. Carbon neutrality objectives and the growth of homestays have forced hotel managers to pay more attention to carbon reduction. First, this paper adopted the input–output method to calculate hotel CO2 emissions. It was found that the amount of CO2 emissions in the hotel industry decreased from the year of 2016 to 2018, and there are structural differences in the CO2 emissions of the hotel industry in China. Furthermore, this paper adopted the three-stage SBM-DEA model to evaluate hotel CO2 emission efficiency in 30 provinces in China. The results show that CO2 emission efficiency increased significantly when environmental factors were eliminated. A close observation of different regions shows that the eastern region has a higher CO2 emission efficiency than the western and middle regions. The emergence of homestays has led to increased input slacks in the labor and energy consumption of hotels, which has a negative effect on efficiency indirectly. Finally, implications and recommendations for the hotel industry are proposed.
Highlights
Hotel Industry under the DoubleChina is the world’s largest energy consumer and CO2 emitter
Carbon neutrality refers to enterprises, organizations or individuals offsetting the total amount of greenhouse gas emissions that they directly or indirectly produce within a certain period of time by means of plant afforestation, energy conservation, and emission reduction in order to achieve zero CO2 emissions
Our results indicate that the hotel industry in the middle region has the lowest carbon emission efficiency
Summary
China is the world’s largest energy consumer and CO2 emitter. China account for approximately 30% of global emissions (Data source: “Statistical Review of World Energy 2020” released by BP (British Petroleum)). Carbon neutrality and peak carbon dioxide emissions are dual strategic objectives (“the double carbon objectives”). Carbon neutrality refers to enterprises, organizations or individuals offsetting the total amount of greenhouse gas emissions that they directly or indirectly produce within a certain period of time by means of plant afforestation, energy conservation, and emission reduction in order to achieve zero CO2 emissions. Under the double carbon objectives, more refined research on this issue is necessary. This is one of the research gaps in CO2 emissions
