摘　　要：为顺应锻造企业向绿色低碳转型的发展趋势,以山西定襄某锻造企业的活动水平数据为参考,以钢锻件从原材料到产品的“摇篮到大门”范围为系统边界,对1 t钢锻件生产期间的碳足迹进行核算。结果显示,生产1 t钢锻件的生命周期碳足迹为1.14 tCO_(2)e,其中,购入电力和天然气的碳足迹占比为62%,钢材损耗产生的碳足迹占比为30%。基于碳足迹核算结果,提出钢锻造企业的重点减排路径为节能降耗,其次为提高原材料利用率和良品率,以期为实现企业的绿色、可持续发展提供参考。In order to follow the development trend of green and low-carbon transformation for forging enterprise,taking the actively level data of a forging enterprise in Dingxiang,Shanxi as a reference,and taking the“cradle-to-gate”of steel forgings from raw materials to products as the system boundary,the carbon footprint during the production period of 1 t steel forgings was calculated.The results show that the carbon footprint of life cycle for producing 1 t steel forgings is 1.14 tCO_(2)e,of which the carbon footprint from purchasing electricity and natural gas accounts for 62%,and the carbon footprint from steel loss accounts for 30%.Based on the results of carbon footprint accounting,it is proposed that the emission reduction path of steel forging enterprises should focus on energy conservation and consumption reduction as the key and core,followed by improving the utilization rate and yield rate of raw materials to provide reference for achieving green and sustainable development of enterprises.
