SMETA (Sedex Members Ethical Trade Audit) 4-pillar certification represents that a company has undergone an ethical trade audit based on the four pillars of SMETA. The four pillars include labour standards, health and safety, environment, and business ethics.
Auditors who have been trained in the SMETA methodology and are recognized by Sedex (the organization that manages the SMETA audit program) give the said certification. The certification is recognized globally and is often required by retailers, brands, and other stakeholders as a condition of doing business.
It is a way for companies to demonstrate their commitment to ethical and responsible business practices and to differentiate themselves from competitors.
