The Sedex system is an online database which allows members to store, share and report information about ethical and responsible practices in their supply chain. Although Sedex does not enforce its own standard, it encourages members to have their companies assessed according to the ETI code, developed by the Ethical Trading Initiative. The code focuses upon safety and human rights for workers, and bans child labour, (semi-)slavery, and discrimination.

The main advantage for registered members is that suppliers and buyers can do business in the knowledge that their business partners operate in a socially responsible fashion. The Sedex system thus creates trust based upon transparency.
