What Is the Higg Index?

The Higg Index is a suite of sustainability measurement tools developed by the Sustainable Apparel Coalition (SAC) — an industry alliance that includes H&M, Nike, Adidas, Patagonia, Gap, Marks & Spencer, and over 250 other brands, retailers, and manufacturers. The Higg Index allows brands and factories to measure, score, and compare environmental and social performance across the supply chain using standardised metrics. Understanding the Higg Index is now a prerequisite for working with most major EU and US fashion brands.

Sustainable textile factory Higg Index FEM scoring Pakistan
H&M required Higg FEM self-assessment from over 1,400 strategic suppliers globally in 2024.

For Pakistani factories, the most important module is the Higg Facility Environmental Module (FEM). If a brand asks your factory to “complete Higg” or “submit your Higg score,” they are referring to the FEM — a self-assessment covering energy use, water use, wastewater discharge, air emissions, chemical management, and waste management. In 2024, H&M alone required Higg FEM self-assessment from over 1,400 strategic suppliers globally, including 200+ in Pakistan.

The Three Higg Modules That Affect Pakistani Factories

Higg FEM
Facility Environmental Module

Self-assessment of environmental performance. 7 sections: energy, GHG, water, wastewater, air emissions, waste, chemicals. Annual self-assessment + optional third-party verification. Completed at the factory level.

Higg FSLM
Facility Social Labour Module

Self-assessment of social and labour conditions: wages, working hours, freedom of association, workplace safety, grievance mechanisms. Increasingly required alongside FEM for complete Higg factory profile.

Higg MSI
Material Sustainability Index

Environmental impact scoring for raw materials — cotton, polyester, nylon, wool, etc. Relevant for fabric mills and raw material suppliers. Brands use MSI data to compare material environmental footprints.

Higg FEM Scoring: What Each Section Covers

Tracks total energy consumption (electricity, gas, steam, coal) in kWh/equivalent per unit of production. Asks about renewable energy proportion, energy audits, and reduction targets. Most Pakistani factories score low here due to WAPDA grid dependence and lack of solar integration.

Water consumption per unit of production (litres per garment equivalent). Asks about water recycling, metering, and reduction programmes. Wet processing (dyeing) is the major water use point. Best practice is below 100 litres per kg fabric dyed.

Covers ETP (effluent treatment plant) operation, discharge parameters (BOD, COD, pH, colour, heavy metals), and ZDHC Wastewater Guidelines compliance. Factories discharging into municipal systems without ETP score 0 on this section.

Chemical inventory, MSDS/SDS availability, ZDHC MRSL conformance, and worker PPE. Factories using ZDHC Gateway-listed chemicals score significantly higher. This section is where ZDHC compliance has the most direct Higg FEM impact.
