基于碳排放抵扣的碳排放计量方法研究——以钢材生产为例

Research on the Quantitative Method of Carbon Emission Based on the Offset of Carbon Emission——a Case Study of Steel Production

随着全球气候变暖趋势的不断加剧,碳排放已经成为国内外学者研究的重点,尤其是钢材生产的碳排放情况更是重中之重。针对国内钢材生产碳排放现状,本文提出了一种碳排放抵扣计量方法,该方法以钢材生产碳排放计量基本方法——质量守恒法和活动水平因子法为基础,着重分析了钢材生产过程的理论碳排放、实际碳排放、碳排放抵扣以及企业理论直接减排潜力。并以某钢材生产企业为实例,对该企业生产流程中碳排放进行抵扣分析,识别与企业直接减排潜力相关的物质及流程,增加副产品及二次能源利用度,最后对企业碳减排潜力的研究方向做出初步展望,提出碳减排潜力的有利发展方向。进一步证明该方法的实用性,为该方法在钢材生产企业碳排放权的实际应用提供了理论基础。

With the increasing trend of global warming,carbon emissions have become the focus field of domestic and foreign scholars,especially the carbon emissions of the steel production industry.According to the current situation of carbon emissions of domestic steel production industry,this paper proposes a quantitative method for the offset of carbon emissions,it based on the basic methods of steel production industry carbon emission include mass balance method and activity level factor method,this paper focuses on the analysis of the steel product process theoretical carbon emissions,actual carbon emissions,carbon emissions offset and enterprise theoretical directly reduction potential.With an example of a steel production enterprise,it analysis the quantitative of carbon emissions offset,recognition the related materials and processes of enterprise direct reduction potential,increased by-products and secondary energy utilization.Finally,make preliminary outlook on the research of enterprise carbon emission reduction potential direction,proposal the favorable development direction of carbon emission reduction potential.It further proves the practicability of this method,which provides a theoretical basis for the practical application of carbon emission permits in the steel production enterprise.
