Carbon emission accounting method of construction project during construction period

Abstract

In the environmental impact assessment of construction projects, construction projects often involve a number of projects, and the construction period is complex, and there are many energy-saving and emission reduction links. Therefore, it is difficult to objectively and scientifically establish a set of energy-saving and emission reduction index system and accounting methods. The selection and quantification of the index system and accounting model are all technical difficulties. In this paper, the energy consumption and carbon emissions in the construction process of a project are calculated, and the internal and external carbon emissions are calculated respectively, which provides a basis for the subsequent energy conservation and emission reduction of the project.
