Sedex and SMETA are international certification standards that help ensure ethical and responsible business practices within global supply chains. Sedex provides a platform for sharing ethical data and managing ethical risks, while SMETA is a social compliance audit methodology that covers labor standards, health and safety, environment, and business ethics. Both Sedex and SMETA certifications involve a self-assessment questionnaire and an independent third-party audit to evaluate suppliers' ethical and responsible practices. These certifications demonstrate a supplier's commitment to ethical business practices and help build trust and transparency within the supply chain.
