Carbon footprint (CFP) reflects the greenhouse gases (GHGs) produced by human activities or products throughout the life cycle, which is an important tool for assessing and managing greenhouse gas pollution. The reduction of Carbon footprint is an important topic today, and each of us needs to minimize our CFP in order to protect our planet. In this paper, the basic cotton denim jackets was played an research object roles to exploring the impact on the environment during the process of producing cotton denim jackets. Which based on the theory of industrial carbon footprint and combing with the production process chain of denim jackets, setting the accounting boundaries and functional units, the denim jacket can be divided into cutting, sewing, and finishing the three links in industrial production of carbon footprint. With the calculation and analyzation industrial carbon footprint of the denim jacket. The results show that the carbon footprint of denim jackets exceeds 1000 kg CO₂ during the cycle from cutting to sewing and finishing. The largest carbon footprint is generated in the sewing process, which are about twice as high as the cutting process. The carbon footprint emissions of each piece of denim jacket is 1.75 kg CO₂. Therefore, optimizing the production line in the sewing process, adopting high energy-efficient processing equipment and clean energy can better reduce the industrial carbon footprint of denim clothing. It also provided reference and basis for the supervision and evaluation of carbon emission by clothing manufacturers

碳足迹（CFP）反映了人类活动或产品在整个生命周期中产生的温室气体（GHG），是评估和管理温室气体污染的重要工具。减少碳足迹是当今的一个重要话题，我们每个人都需要尽量减少我们的 CFP 以保护我们的星球。本文以基本款棉质牛仔夹克作为研究对象，探讨棉质牛仔夹克生产过程中对环境的影响。以工业碳足迹理论为基础，结合牛仔夹克的生产过程链，设定核算边界和功能单元，将牛仔夹克分为裁剪、缝纫、整理三个环节的碳足迹工业生产。 . 随着牛仔夹克的工业碳足迹的计算和分析。结果显示牛仔夹克的碳足迹超过1000 kg CO₂在从裁剪到缝纫和整理的循环过程中。最大的碳足迹是在缝纫过程中产生的，大约是裁剪过程的两倍。每件牛仔夹克的碳足迹排放量为1.75 kg CO ₂。因此，在缝制过程中优化生产线，采用高效节能的加工设备和清洁能源，可以更好地减少牛仔服装的工业碳足迹。也为服装生产企业的碳排放监督评估提供了参考和依据。
