Study and Evaluation of Carbon Emission Calculation Methods for Transmission Line Laying Projects

The urgency of addressing global climate change has led to a widespread agreement on the reduction of carbon emissions. In the realm of electric power infrastructure, assessing the carbon footprint of transmission line installation projects is crucial for advancing a low-carbon economy. This study explores the methodology for calculating carbon emissions in such projects and applies this method to a specific transmission and substation project for evaluation. Focusing on the transmission line installation project, this study initially gathers and synthesizes carbon emission calculation methodologies and criteria from analogous initiatives both domestically and internationally, drawing from existing research and pertinent literature. Subsequently, it delves into the primary carbon emission contributors within the transmission line installation project, encompassing equipment utilization, material manufacturing, transportation, and the construction phase. Then, the carbon emission accounting method of the transmission line laying project is proposed, and a case study of an actual transmission project is carried out to analyze and calculate the carbon emissions generated by each part of the construction, and the results of the carbon emissions of each part are compared. In conclusion, the study assesses the carbon emission figures for the transmission line installation project, suggests viable strategies for carbon and emission reduction, evaluates the practicality of the proposed calculation approach, identifies its limitations, and outlines potential directions for future enhancement. This aims to offer both practical guidance and theoretical insights, contributing to the sustainable growth of the electric power sector.
