Fast fashion is driving the continued growth of the fashion industry's carbon emissions. Understanding how fast fashion consumption exacerbates carbon emissions is critical to guide mitigation strategies for the fashion industry. Taking jeans, a typical fast fashion product as an example, this study developed an LCA model to assess the carbon footprint of fast fashion consumption at global and national levels, and mitigation potentials of product service systems-related scenarios were then explored. Results show that the carbon footprint of fast fashion consumption is 2.50 kgCOe/one wear jeans, 11 times higher than that of traditional fashion consumption. Jeans production and cross-broad transportation contributed 91 % of the carbon footprint of fast fashion consumption. Developed countries have a 53 % higher per capita carbon footprint of fast fashion consumption than developing countries. The second-hand trading model has the highest mitigation potential, reducing carbon emissions by 90 %. This study proposed an analytical framework for the carbon footprint of fast fashion consumption, which provides the basis for the environmental footprints of fast fashion products. Our findings provide insights into the carbon footprints of traditional and fast fashion consumption and strategies for the transition to circular fashion.
快时尚正在推动时尚产业碳排放的持续增长。了解快时尚消费如何加剧碳排放对于指导时尚产业的减排策略至关重要。以牛仔裤这种典型的快时尚产品为例，本研究开发了一种生命周期评估模型，以评估全球和国家层面快时尚消费的碳足迹，随后探讨了与产品服务系统相关情景的减排潜力。结果表明，快时尚消费的碳足迹为每穿着一次2.50千克二氧化碳当量牛仔裤，比传统时尚消费高出11倍。牛仔裤生产和跨国运输占快时尚消费碳足迹的91%。发达国家快时尚消费的人均碳足迹比发展中国家高53%。二手交易模式的减排潜力最大，可减少90%的碳排放。本研究提出了一个快时尚消费碳足迹的分析框架，为快时尚产品的环境足迹提供了依据。我们的研究结果为传统和快时尚消费的碳足迹以及向循环时尚转型的策略提供了见解。
