基于LCA的高速公路施工期碳排放量化边界界定

Delimitation of Carbon Emission QuantificationBoundary on Expressway Construction PeriodBased on LCA Theory

交通运输是碳减排潜力最大、难度最高的领域之一,而公路交通碳排放在交通运输碳排放中占首位。为把握公路施工碳排放的特点,对工程建设碳排放进行有效盘查,该研究依托某高速公路建设工程,提出对高速公路施工期碳排放界定量化边界的方法。结果表明,通过LCA理论对高速公路施工期的碳排放边界界定,揭示了施工期碳排放的全过程,有助于准确核算公路施工期碳排放数量,为公路施工碳排放控制提供了重要依据。

Transportation is among the most promising,but also most challenging areas for carbon emission reduction,in which highway transportation is the major source of carbon emissions.This study aims to define quantification boundary of the characteristics of carbon emissions from highway construction,and to provide a reference for carbon emissions calculation from engineering construction.The findings show that delimitation of carbon emission boundary for expressway construction period through LCA theory will benefit accurate accounting of carbon emissions in expressway construction period,while providing an important reference for the control of carbon emissions in highway construction.
