Résumé
The fashion industry is facing significant challenges in terms of environmental, social, and economic issues. This thesis is at the heart of a transition within the fashion sector towards increased circularity and transparency in order to meet regulatory changes and the growing expectations of consumers.In the first section, we define the terms « transparency » and « traceability » within the context of sustainable development and outline the concept of product transparency. Next, we assess the dynamics of brand transparency through a field study covering the practices of 54 brands over a period of 3 years.Following that, we present three industrial projects that demonstrate the application of Information and Communication Technologies (ICT). These projects encompass a voluntary transparency initiative by a footwear retailer, the development of a traceability tool for the French wool industry, and the alignment of a group with Article 13 of the AGEC law.We delve into the development of an ambitious ICT framework: the Digital Product Passport (DPP) for the textile industry. We present our methodology for developing a data model for a DPP using Grounded Theory, which allows for the integration of various sources such as documents, testimonies, regulations, and scientific literature. This data model enables us to aggregate information related to products, processes, and stakeholders, facilitating their collection and utilization by all actors involved in circular practices.Our data model for the DPP in the fashion industry enables us to evaluate three existing frameworks. This evaluation leads to the formulation of recommendations aimed at enhancing the content of DPPs within the sector.
