Trade was deep rooted in the world locally. The global doors opened up more recently and new ideas for trading and making product in multiple locations are even more nascent, close to the 80 s. This gave us the topic of global value chains (GVC) to study, reflect and understand the shift in global trade. Since then, the subject has gained interest from both academics and decision-makers. Since the development of the topic of global value chains (GVCs), production has altered a lot. Due to lower transportation and communication charges, many firms have abandoned the custom of making all their products and services in a single nation and inside their organisational borders. GVCs can offer various benefits for firms and countries, such as access to new markets, technologies, skills, and resources. However, GVCs also pose challenges like coordination costs, quality control, environmental and social standards, and value-added distribution. This has led to the advancement of literature; however, there remains a gap in understanding how the barriers and drivers of Sustainability in GVC affect it. This study has been undertaken to address this gap and has used the Grey-DEMATEL technique. Study shows significant relationships among factors like Greenwashing, the COVID-19 pandemic, and Blockchain technology, which policymakers can use to improve Sustainability within the value chains.
