The increasing pressure for social responsibility and sustainability that multinational enterprises (MNEs) are facing in their global operations represents one important emerging phenomenon within the international business field. In this book chapter, we present an in-depth case study on how a global fashion MNE develops and implements sustainability practices in their operations in an emerging market context. The case study focusses on the MNE’s work related to energy efficiency and renewable energy in the production market of Bangladesh. The purpose of this chapter is to advance the understanding about particular practices pertinent to a proactive approach to corporate social responsibility (CSR). The chapter contributes to ongoing discussions within the international business field on the role of MNEs in driving and implementing sustainability practices. We add an in-depth understanding of the proactive CSR practices undertaken by an MNE, in an emerging market context.
