The Supplier Ethical Data Exchange (Sedex) is a not-for-profit membership organization that provides a platform for companies to share information about their supply chains, including ethical trade practices. Sedex members can use the Sedex platform to conduct audits of their suppliers, share audit results, and collaborate on improving ethical trade practices.

Sedex members who are committed to ethical trade often use the Sedex Members Ethical Trade Audit (SMETA) methodology. SMETA is a comprehensive audit that assesses a supplier's compliance with ethical trade standards, including labor standards, health and safety, and environmental practices.

SMETA audits are conducted by independent auditors who are accredited by Sedex. The auditors assess the supplier's operations against a set of criteria that are based on international standards, such as the Ethical Trading Initiative Base Code.

Sedex members who use SMETA can share their audit results with other members of the Sedex community. This allows members to identify potential risks in their supply chains and take steps to address them.

Sedex also provides a number of other resources to help members improve their ethical trade practices. These resources include training courses, webinars, and online tools.

Sedex is a valuable resource for companies that are committed to ethical trade. By using Sedex, companies can improve their supply chain transparency, reduce risks, and promote ethical business practices.
