The GOOS Index is supported by an international advisory group of over 20 experts across 15 countries, bringing together academics, researchers, and industry professionals from across the fashion ecosystem. Their fields span textile science, sustainability strategy, certification frameworks, supply chain governance, and circular design. Advisors are distinguished for their expertise and independence of thought, ensuring that guidance reflects informed judgment and addresses the complexity of the field, rather than commercial or institutional agendas. This diversity of perspectives strengthens the analytical integrity and global relevance of the Index.
