Research on carbon emission calculation and carbon reduction suggestions for expressway construction in Anhui province
Year: 2024
Type: conference-paper
Abstract: To reduce carbon emissions during the construction period of roads, carbon emission calculations and carbon reduction suggestions for roads have been researched in this paper.The calculation method for carbon emissions and the key influencing factors of carbon emissions during the construction period have been presented and analyzed based on the Ningwu Expressway in Anhui Province.The research results show that the material production phase contributed over 90% of carbon emissions, making it the primary control object for engineering carbon reduction.Interchange engineering contributed the highest carbon emission amount and intensity, which seemed to be the key unit construction that needed control.Cement and steel have a significant carbon emissions impact on interchange engineering, with a proportion over 80% of carbon emissions.Energy carbon emissions mainly came from oil-electric hybrid construction facilities, nearly 3 times higher than the carbon emissions from electrical construction facilities.Suggestions have been proposed to reduce carbon emissions during the road construction period based on the research results, which aim to provide effective support for low-carbon construction and boost transformation development for roads in China.
