【Abstract】 As one of the major carbon emission contributing industries, the low-carbon transformation and emission reduction progress of the textile and apparel industry has attracted much attention. Many textile and apparel brands or enterprises have issued emission reduction or carbon neutral plans and carried out low-carbon sustainable development actions through the management of carbon footprint. In the carbon footprint accounting and evaluation of textile and apparel products, it is difficult for the inventory data to trace the source, the accounting process is not transparent and the accounting results are not traceable. Such a situation leads to high accounting cost, lack of supervision of scientific and normative accounting process and low efficiency of accounting results. It is necessary to establish a traceable accounting method for carbon footprint of textile and apparel products with clear, transparent and traceable sources and protection of enterprise privacy.This paper reviews the research status of carbon footprint tracing of textile and apparel products, and analyzes the limitations of a few researches and applications that use blockchain technology to trace the carbon footprint of textile and apparel products: the tracking method is not explained in detail and the transparency of the accounting process is not achieved; by summarizing the characteristics of blockchain and the current research status of tracing application, this paper expounds the advantages and challenges of applying blockchain to the carbon footprint traceability of textile and apparel products. Combined with the modular carbon footprint accounting method of textile and apparel products, the working mechanism and system architecture of carbon footprint tracing and accounting of textile and apparel products based on blockchain technology are designed. The product carbon footprint data, module carbon footprint data, module carbon footprint accounting methods and source data are traced. At the same time, the inefficiency and privacy leakage problems of typical blockchain are avoided by expanding storage and data access control mechanisms. This paper demonstrates the system tracing process through case data and verifies the system can realize the traceable query of “product-module-method-source data” and control access of product carbon footprint, and can establish traceable and transparent carbon footprint module library, realizing the efficient utilization of accounting results of textile and apparel products. In addition, the limitations of the system in organization and information processing are summarized.This paper proposes a carbon footprint tracing scheme for textile and apparel products based on the blockchain. Future research should pay close attention to the innovation and practical application of blockchain technology, and improve the availability and scalability of the blockchain tracing system through multiple chains, side chains and other ways. The paper can be used as the basis of carbon footprint tracing at the stage of consumer use and waste, and researchers can also take the traceability system and solution in this paper as the basis to explore the research in the fields of carbon management of the textile and garment industry, carbon emission trading, carbon financial investment, etc.更多还原
