Analysis on Influence Factors for the Whole Life-Cycle Carbon Emissions of Highway and Carbon Accounting

Abstract

The CO2 emissions of highway transportation industry are huge. There are many factors which are affecting highway carbon emission. To reduce vehicle emissions, and improve the design, construction, operation and management of highway, which was the main purpose of the study. The whole life cycle of highway was divided into construction stage and operation stage. Factors which affected carbon emissions of different highway stages were discussed, and they were artificial carbon emissions, energy consumption of machinery and equipment, building materials, pavement types, low carbon management, types and carbon emission coefficients, running speed, radius of curvature of horizontal curve, road roughness, gradient of longitudinal curve, traffic volumes, plant carbon sink. Put forward the highway carbon emissions accounting methods, and established the carbon accounting models. The research will be helpful to reduce carbon emissions of highway transportation industry.
