The evolution of standards and certification in agri-food chains has taken place over nearly 40 years. The dynamics that led to this form of private governance have also changed over time. Contemporary issues such as climate change, biodiversity loss, and seeking to develop a food system that is resilient and sustainable has led to the emergence of new principles, practices and outcomes that the agri-food supply chain must deliver. This chapter reflects on these trends and the themes that run through the book to consider how we deliver safe, sustainable and socially responsible supply chains, now and into the future.
