Carbon emission reduction calculation for the green transformation of traditional hotel design

The green transformation design of traditional hotels aims to reduce the consumption of materials and energy and reduce the emission of harmful substances. Carbon emission, usually used to measure energy consumption, is a representative indicator to evaluate the effect of the green transformation process. This paper adopts the emission factor method to measure the carbon emission reduction in the process of hotels’ green transformation from the whole life cycle of hotels, and the results show that: 1) From the perspective of the hotel life cycle, the construction process is the stage with the most carbon emissions. 2) From the perspective of a single hotel, high-star hotels have larger emissions than low-star hotels; 3) As the number of three and four-star hotels far exceeds the five-star hotels, overall, four-star hotels ranked first in total emission reduction. 4) From the perspective of provinces, the hotel industry emission reduction potential of different provinces varies greatly, among which Guangdong, Zhejiang, and Jiangsu provinces are at the top of the list. The future carbon reduction potential of the Chinese hotel industry is very considerable. The content of this paper enriches the research in the field of carbon emission measurement and also provides a reference for the management agency to designate the carbon peaking and carbon neutrality goals of the hotel industry.
