| Abstract: |
| 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. This paper provides a basic support for the synergistic development of pollution reduction and carbon reduction in non-ferrous metal smelting enterprises. |
