Sustainable development with ecological protection has gained global significance across society because of continuing environmental degradation. It causes green supply-chain management to be an area of interest among researchers and practitioners. Existing literature related to green supply chain indicates that most of the scholarly works have been limited to the manufacturing context and retailing has not been paid enough attention. It signifies that integrating green policies into retail sector is a new potential area of research from academicians' and practitioners' point of view. This chapter discusses about the drivers, barriers, different dimensions, issues, existing environmental practices and policies adopted by leading retailers, future research avenues, different green polices adopted by various organizations and government bodies in the area of retailing. Thus it facilitates researchers, industry practitioners, policy makers to find the existing works, new research opportunities as well as to improve practices and policies.
