基于数据分配的铝铸件生产过程细粒度碳排放核算方法
Fine-grained Carbon Emission Accounting in Aluminum Casting Production Processes Based on Data Allocation
摘要
Abstract
A data allocation method that accommodated the heterogeneous on-site data collection capa-bilities of aluminum casting enterprises was proposed,enabling fine-grained carbon emission accounting at the single aluminum casting level,differentiated by product,model,and batch,without requiring addi-tional investment in data collection infrastructure.According to the granularity and interval of carbon emission-related production data,enterprise data acquisition capabilities were categorized into three levels,and corresponding allocation strategies were developed for each level to derive fine-grained energy and ma-terial activity levels for individual aluminum castings.Product carbon emissions were calculated using the emission factor method,and a correction mechanism was established to incorporate the effects of internal scrap recycling and external scrap sales.A case study on aluminum wheel production was conducted to vali-date the proposed method.The results demonstrate that the method effectively overcomes the bias induced by the constant operating condition assumption inherent in traditional literature-based approaches,thereby improving the accuracy of carbon accounting results.关键词
