Research on Carbon Emission Allocation in Urban Public Buildings in Guangxi

Abstract

Currently, the allocation of carbon emissions in public buildings in China is mainly concentrated at the provincial level. This paper uses a hybrid research method of entropy method and data envelopment analysis under zero-sum games to study the allocation of carbon emissions in public buildings among different cities in Guangxi province. This method is flexible and comprehensive, taking into account various factors. Finally, through calculations, the feasibility of this method is verified, and the allocation of carbon emissions in urban public buildings in Guangxi province, under the condition of fixed total carbon emission, is determined. Among them, Nanning and Liuzhou can increase their carbon emission quotas by 96.8% and 91.6%, respectively, to improve economic efficiency and achieve the highest efficiency in carbon emission investment. On the other hand, baise needs to significantly reduce its carbon emission quota by 82.9% due to its lower efficiency. Guigang city, because of the balance between carbon emission investment and the current economic scale, requires a smaller adjustment, within 10%. This approach will help the government's efforts to reduce carbon emissions.
