Corporate Social Responsibility (CSR) has emerged as a significant movement in the food sector. Within the seafood sector, leading retail, food service, and their supply chain partners in manufacturing and importing have evolved their corporate sustainability and sourcing policies. For the first time, our research team has compiled and analyzed global data from Corporate Social Responsibility audits (Best Aquaculture Practices (BAP), Business Social Compliance Initiative (BCSI) and Sedex Members Ethical Trade Audit (SMETA)), together with current research and industry best practices. The audit data covers the supply chain from farm (land and offshore) to processor. We explore multiple assessment criteria and point to opportunities for improvement.
