JiSMART2022—006: A Comparative Study of Carbon Emission Accounting Methods in Building Sector -- A Case Study of Shenzhen

Abstract

The carbon peak in the building sector is an important part of the realization of China's carbon peaking and carbon neutrality goals. In 2019, the total carbon emission of the building sector, including material production, building construction and operation stages, accounted for 50.6% of the total carbon emission in China, according to China Building Energy Consumption and Carbon Emission Research Report (2022). To achieve the goals in the building sector more scientifically and reasonably, it is necessary to pay attention to the accuracy of carbon emissions accounting methods. Therefore, this paper aims to take Shenzhen as a case to develop a carbon emission accounting method based on the characteristics of the city. The current accounting methods of the building sector is reviewed and analyzed to find the strengths and the weaknesses of the methods initially. And then according to the characteristics of Shenzhen, an enhanced method is proposed. This paper analyzed the accounting methods in the building sector at the city level, and offered an enhanced method for Shenzhen, which contributes to selecting the more proper method for accounting, and thus laying a foundation for subsequent research.
