This thesis presents the results of an explorative case-based research which investigatessustainable supply chain management (SSCM) in the Swedish fast fashion company GinaTricot. Drawing from a general SSCM framework established by Cetinkaya, Cuthbertson, Ewer, Klaas-Wissing, Piotrowicz & Tyssen’s (2011), the study attempts to fill in the gap ofindustry-specific considerations by investigating how the SSCM guidelines can betransformed into business practices in a fast fashion company. The findings were gathered byapplying a qualitative content analysis on two types of sources: 1) Eight annual sustainabilityreports published by Gina Tricot from year 2013 to year 2020, 2) one complementarysemi-structured interview with the fashion company’s sustainability manager. Based on theestablished theoretical framework, a thematic analysis was applied, identifying awareness ofthe SSCM principles within the company as well as practises and limitations unique to thefast fashion industry. The results of the thesis reveal the fast fashion company Gina Tricotmost significantly addresses sustainability issues by involving suppliers in the process.Supplier partnerships, supplier compliance and audits with systematic follow ups are keypractices which have enabled the enforcement of sustainability standards in supplier factoriesand prevention of sustainability risks that production in developing countries poses. As a fastfashion company, Gina Tricot struggles to balance economic aspects equally with theenvironmental and social principals due to the nature of its supply chain.
