The Supplier Ethical Data Exchange (Sedex) is a not-for-profit, membership organisation for businesses committed to the continuous improvement of ethical performance within their supply chains. Sedex was founded in 2001 by a group of UK retailers to drive convergence in social audit standards and monitoring practices. The aims of Sedex are to ease the auditing burden on suppliers through the sharing of reports and to drive improvements in supply chain Labour Standards.

This Sedex Members Ethical Trade Audit (SMETA) has been developed by the Sedex Associate Auditor Group (AAG), through multi- stakeholder consultation, to provide a best practice reference framework for social auditing and reporting.
