基于LCA的高速公路服务区碳排放核算研究

Research on Carbon Emission Calculation of Expressway Service Area Based on LCA Theory

本研究基于全生命周期评价理论(Life Cycle Assessment,LCA),明确了高速公路服务区全生命周期碳排放核算边界,提出了碳排放核算模型,并以云南省某服务区为例,进行全生命周期碳排放核算。核算结果表明该服务区全生命周期碳排放量为25480.63tCO_(2e),其中运营阶段为13365.62tCO_(2e),占比52.45%;建设阶段为11013.64tCO_(2e),占比43.22%;拆除阶段为1101.37tCO_(2e),占比4.33%。可见运营期是高速公路服务区碳减排的关键阶段,由此提出了各阶段具体降碳措施,为低碳服务区建设提供了可参考思路。

Based on Life Cycle Assessment Theory(LCA),the carbon emission accounting boundary of expressway service area was defined,and this study proposed a carbon emission calculation model.Meanwhile,an expressway service area in Yunnan Province was selected for carbon emission calculation.The research results showed the total carbon emissions of this expressway service area were 25480.63 tCO_(2e),including13365.62 tCO_(2e) of the operation stage,11013.64 tCO_(2e) of the construction stage,and 1101.37 tCO_(2e) of the demolition stage.The proportion of carbon emissions were 52.45% of the operation stage,43.22% of the construction stage,and 4.33% of the demolition stage.So the operation stage was a key phase for carbon emission reduction of expressway service area,and the carbon emission reduction measures were proposed.That would offer the thought and lessons for the construction of low-carbon expressway service area.
