Social and Ethical Auditing Standards in Global Supply Chains
The Sedex SMETA (Sedex Members Ethical Trade Audit) is one of the most popular auditing methods for social and ethical audits in global supply chains. Developed by the UK-based non-profit Sedex (Supplier Ethical Data Exchange), SMETA provides a standardized structure to ensure businesses comply with ethical, labour, health, safety and environmental standards in the production and supply of goods.
Sedex and its role in the supply chain
Sedex is a collaborative platform that supports businesses to share and manage information related to social responsibility, business ethics and transparency in the supply chain. Tens of thousands of businesses in more than 180 countries have been using Sedex to demonstrate their commitment to customers, investors and consumers in terms of labor standards and business ethics.
Sedex does not directly perform audits but acts as a bridge, providing the platform, standards and tools for third parties to conduct audits and assessments. Through the Sedex Advance platform, businesses can manage audit data, share information with partners as well as track progress to improve audit findings.
What is SMETA?
SMETA (Sedex Members Ethical Trade Audit) is an audit methodology developed by Sedex, designed to evaluate businesses in the supply chain in terms of the following aspects: labor, health and safety, environment, business ethics. SMETA is not a certification standard, but an audit process to determine the level of compliance with ethical requirements in production and business activities.
SMETA focuses on four main pillars:
- Labour Standards
- Health & Safety
- Environment
- Business Ethics
Organizations can choose to audit SMETA 2 pillars (labor and health & safety) or 4 pillars (including environment and business ethics), depending on customer requirements or industry specifics.
SMETA Audit Process
The SMETA audit process typically includes the following key steps:
- Preparation and planning: The production facility and the audit unit agree on the date, scope and prepare relevant documents. The audited entity needs to provide necessary information about its operations, personnel, policies and working conditions.
- On-site inspection: A team of auditors will go directly to the facility to observe the facts, interview workers, check records, documents and evaluate working conditions, safety, hygiene, fire protection, conduct anonymous interviews, and inspect production areas.
- Audit report: Upon completion, the auditor will prepare a report using the standardized SMETA form, clearly stating the findings, compliance points, and remaining issues.
- Corrective Action Plan: If a non-conformity is detected, the business must make a corrective plan, commit to an improvement roadmap, and re-examine if necessary.
SMETA reports are shared via the Sedex platform, allowing customers and partners to access and track the supplier’s improvement process.
