Abstract: Current environmental issues and challenges have a direct impact on firms' strategic and operational decisions in terms of location, transport and production. In this work, we propose to investigate a firm that reconsiders its location and production decisions under a carbon tax policy on transport-related carbon emissions. Traditionally sustainable facility location models under carbon pricing scheme assume that firm supply is given (complementary essential inputs). In our framework, input mix and location decision are allowed to vary simultaneously. The relationship between the production level and the input quantities is captured through a production function that enables different degrees of substitutability among the raw material quantities. The results show that variation in the elasticity of substitution across the different types of inputs affects the firm location and supply choices. Moreover, it plays a crucial role in controlling the level of the pollution stemming from commodity shipping through adjustments in the input supply quantities. Our analysis also reveals the sensitivity of the facility location decision to a higher carbon tax when firm has a high flexibility on its ability to substitute among the input quantities.

- "CSR implementation for the sustainable supply chain performance: A system dynamic approach"
Présentation de Thi Lan Anh Nguyen (Doctorante CREM, Université Rennes 1, pôle ORN – Organisations, Réseaux, Numérique)
Abstract: Corporate social responsibility (CSR) seems ever more important in the current context of globalized supply chains, especially for for-profit corporations. To cope with the increasing pressure of public concerns for socially responsible activities, garment firms are facing the decision of engaging in CSR. Therefore, the purpose of this paper is to investigate the question of the CSR engagement problem in the garment supply chain (SC). Particularly, by using the system dynamics (SD) approach, we try to find conditions that would make it more profitable for SC actors to embrace CSR. Through sensitivity and comparative analysis, we examine the influence of factors on CSR implementation of SC actors and indicate the thresholds of consumer’s demand responsiveness to firms’ CSR efforts level as well as other CSR-related costs so that firms may obtain higher benefits in comparison with the case where CSR is absent. Our study is also the first one to simultaneously incorporate three dimensions of CSR in one comprehensive model. Therefore, our proposed model m"ight provide a theoretical and managerial foundation that can reinforce the consideration of CSR engagement in the SC.
