This book addresses the issue of sustainability in the luxury industry, which has become a major topic of concern for brand managers, scholars, policy-makers, the media, and academia. Spanning 13 chapters, the authors provide insights from developed and developing countries, whilst at the same time exploring a variety of issues within sustainable luxury, the hidden value of secondhand, eco-luxury, circular economy principles and perceptions, ethical sourcing and eco-label strategies. All of which can be linked to the broader theme of SDG12: Responsible Production and Consumption. Thus, the book not only has a wide geographical scope but also brings together a collection of scholars spanning many disciplines such as marketing, management, textiles, fashion, economics, and digital media. Offering a combination of empirical and conceptual works, the book also provides important insights for future research enquiries.
