摘要
冶炼是有色金属行业碳排放核心环节,占比达90%以上。基于有色金属冶炼企业碳排放特征分析,从碳绩效投入、碳绩效产出两个维度,尝试构建有色金属冶炼企业多元低碳绩效评价指标体系。开展某铅冶炼企业应用初探,层次决策模型剖析权重。低碳绩效投入指标中碳源控制>资金费用>投入管理;其中碳源控制下一级指标权重净购入电力消耗控制>化石燃料燃烧消耗控制>冶金还原剂消耗控制>其他生产过程碳源直接消耗控制>净购入热力消耗控制。低碳绩效产出指标中碳排放强度>产出管理>碳处理能力>碳治理效果;其中碳治理效果下一级指标权重废气排放达标情况>废水处理达标情况>固体废物处理处置规范情况,产出管理下一级指标权重碳排放数据管理>碳交易管理>碳信息披露。基于不同情景,初步阐释碳减排策略效率,为有色金属冶炼企业低碳绩效评价提供借鉴。
Accounting for over 90%,smelting is the core link of carbon emissions in the non-ferrous metal industry.Based on the analysis of carbon emissions characteristics of non-ferrous metal smelting enterprises,this paper attempts to construct a system with diversified low-carbon performance evaluation indicators,including carbon performance input and output.We conduct an initial application of a certain lead smelting enterprise,analyzing the weights of the hierarchical decision-making model.The results show that in low-carbon performance investment,carbon source control>capital cost>investment management.Among them,the weight of the primary indicator under carbon source control is net purchased electricity consumption control>fossil fuel combustion consumption control>metallurgical reducing agent consumption control>direct consumption control of carbon sources in other production processes>net purchased heat consumption control.In the low-carbon performance output indicators,carbon emission intensity>output management>carbon treatment capacity>carbon governance effect.Among them,indicator weight under the carbon governance effect shows emission status of exhaust gas up to standard>wastewater treatment status>solid waste treatment and disposal status.Indicator weight under output management shows carbon emissions data management>carbon trading management>carbon information disclosure.Based on different scenarios,the efficiency of carbon reduction strategies is further explained.Based on different scenarios,the efficiency of carbon emission reduction strategies is preliminarily explained,providing reference for the low-carbon performance evaluation of non-ferrous metal smelting enterprises.
