Research and Application of Carbon Emission Accounting Methods during the Construction Period of Highways in Guangdong Province
After comparing the characteristics of the two current carbon emission accounting ideas,and analyzing the characteristics of highway construction projects in terms of quality,schedule and measurement,this paper chooses an accounting method based on the "bottom-up" thinking of carbon emission factor method and actual measurement method to carry out carbon emission accounting during the construction period of expressways. After analyzing the international carbon emission accounting boundary and the carbon emission accounting boundary of some leading industries,the carbon emission accounting boundary during the construction period of the expressway was defined. Relying on the Xiongxin Expressway in Guangdong Province,the carbon emission during the construction period of the project was calculated. The total carbon emission during the construction period of the project was 628700t,and the carbon emission intensity per kilometer was 15216t/km. Carbon emission intensity 3804t/km/lane. From the perspective of carbon emission sources,the carbon emissions of a few building materials and equipment accounted for more than 80％ of the total carbon emissions. The object and starting point of carbon emission control were analyzed,and some carbon reduction measures were selected to reduce carbon emissions in the construction stage.
