Real-World Carbon Emissions Evaluation for Prefabricated Component Transportation by Battery Electric Vehicles

As the first and second largest industries of greenhouse gases (GHG) emissions, the green development of construction industry and transportation industry is related to whether human society can have a sustainable future. This study focuses on the transportation process of prefabricated components in the stage of assembly building, explores the characteristics of battery electric vehicles (BEV) in GHG emissions. The true performance of components' transportation carbon emissions is obtained under different external parameters through the real-world experimental method. After preliminary screening of variables through correlation analysis, the full load ratio, average speed, atmospheric temperature and whether the air conditioner is on are determined as the regression parameters of component transportation carbon emission factors. The results show that BEV can reduce GHG emissions by 36.18% - 54.69%. The study is conducive to play the role of BEV in GHG emission reduction and promote the low-carbon innovation of the fabricated construction industry
