Introduction to SEDEX and Pillar 4 Certification

In today’s increasingly transparent and ethically conscious global market, Pillar 4 SEDEX Certification is becoming a vital benchmark for businesses committed to responsible sourcing and sustainable operations. Pillar 4 refers to the SMETA (Sedex Members Ethical Trade Audit) 4-Pillar Audit, which expands upon the core 2-pillar audit by including environmental performance and business ethics—two critical areas for comprehensive corporate social responsibility (CSR).

By undergoing a Pillar 4 audit, companies demonstrate not only their commitment to labour standards and health & safety, but also to environmental sustainability and ethical business conduct. This certification is highly regarded by global brands, retailers, and procurement departments across multiple sectors.

What is Pillar 4 SEDEX Certification?

Pillar 4 SEDEX Certification involves a SMETA 4-Pillar Audit, a robust ethical audit process that evaluates a company’s practices across four key areas:

1. Labour Standards

2. Health & Safety

3. Environmental Management

4. Business Ethics

The audit is based on:

• The ETI Base Code (Ethical Trading Initiative)

• ILO (International Labour Organization) conventions

• National laws and regulations

• SEDEX guidelines and industry-specific standards

Unlike traditional certifications, SEDEX is a collaborative data platform that facilitates the sharing of audit results, enabling transparency and risk management throughout the supply chain.
