Research on Iron and Steel Logistics Carbon Emissions Reduction Strategy Based on System Dynamics

在对钢铁物流过程碳排放系统因果关系深入分析的基础上,构建了钢铁物流过程碳排放系统动力学模型,模拟了运输结构、能源效率和货运强度相关参数对钢铁物流过程碳排放量的影响。研究发现:铁路比重、水运比重和能源效率增加,钢铁物流过程碳排放量明显减少;运输距离对物流过程碳排放影响重大,具有很大的优化价值。最后提出了优化运输结构、提高能源效率和降低货运强度的相关碳减排策略。

This paper built the iron and steel logistics system dynamics model of carbon emissions with an in-depth analysis on the iron and steel logistics system causality, and simulated the effects of related parameters on the iron and steel logistics carbon emissions, which are structure of transport, energy efficiency and the intensity of freight. The study shows that： with the increase of the proportion of the railway, the proportion of water transportation and energy efficiency, iron and steel logistics carbon emissions decrease correspondingly. Transport distance has major influence on logistics carbon emissions, and having a lot of optimization values. Finally, the paper put forward related carbon emission reduction strategy from three aspects： optimizing the structure of transport, improving energy efficiency and reducing the intensity of freight.
