What is Higg Index?
The Higg Index is a suite of tools developed by the Sustainable Apparel Coalition (SAC) (now Cascale) to help measure and improve environmental, social, and ethical performance in the apparel, footwear, and textile industries.
Overview: What Is the Higg Index?
-
Launched: 2012
-
Created by: Sustainable Apparel Coalition (SAC), which includes:Brands (e.g., Nike, Patagonia, H&M),Retailers,Manufacturers,NGOs,Academic institutions
-
Purpose: To provide a standardized, science-based framework for assessing sustainability across the entire product life cycle, from raw materials to end of use.
Higg Index Toolset Breakdown
There are five primary modules in the Higg Index:
| Tool | Purpose |
|---|---|
| 1. Higg FEM (Facility Environmental Module) | Measures environmental performance at factories (e.g., energy, water, emissions, waste). |
| 2. Higg FSLM (Facility Social & Labor Module) | Assesses working conditions and social/labor practices at manufacturing sites. |
| 3. Higg BRM (Brand & Retail Module) | Evaluates sustainability practices at the brand or retailer level (governance, purchasing practices, etc.). |
| 4. Higg MSI (Materials Sustainability Index) | Measures environmental impacts of different materials (e.g., cotton, polyester). |
| 5. Higg PM (Product Module) | Calculates cradle-to-gate life cycle environmental impacts of individual products. |
What Does the Higg Index Measure?
-
Environmental:
-
Greenhouse gas emissions
-
Water use
-
Chemical management
-
Waste generation
-
Energy consumption
-
-
Social & Labor:
-
Worker health and safety
-
Working hours
-
Wages and benefits
-
Worker voice and grievance mechanisms
-
Child/forced labor risks
-
Scoring and Use
-
Self-assessment is the starting point, often followed by third-party verification.
-
Brands use Higg scores to:
-
Set improvement goals
-
Track supplier performance
-
Share sustainability data (some public via Higg platform or product labels)
-
-
Not a certification, but rather a performance index.
Any Testing Involved?
-
Higg Index doesn’t involve lab testing like chemical or material tests.
-
Instead, it is based on data collection, auditing, and self-reporting, verified by trained professionals.
Controversies and Updates
-
Criticism: Some groups questioned transparency and accuracy (e.g., favoring synthetics like polyester).
-
In 2022, Higg paused product label use in Europe due to regulatory concerns about misleading claims.
-
SAC is working with experts and regulators (e.g., EU, ISO) to make the tool more credible and transparent.
Evolution and the Path Forward
Critics prompted a re-evaluation. Cascale (and its tech partner Worldly) paused consumer-facing tools and pledged deeper reviews of methodology and transparency of data Vogue Business+1. Recent updates include:
-
FEM 4.0 (2023) with improved precision and alignment with emerging standards Wikipedia+1FashionUnited.
-
BRM updates (early 2023) to better align with environmental, social, and governance (ESG) pillars WikipediaFashionUnited.
-
Future ambitions include integrating broader impacts such as biodiversity, land use, and chemical lifecycle and enhancing transparency through open methodologies Fashion → Sustainability Directory.
Summary
| Feature | Details |
|---|---|
| Created by | Sustainable Apparel Coalition (SAC) |
| Main Focus | Sustainability measurement across value chain |
| Tools | FEM, FSLM, BRM, MSI, PM |
| Industries | Apparel, footwear, textiles |
| Use | Internal improvement, B2B data, limited consumer-facing info |
| Verification | Third-party optional |
| Limitations | Not a certification, relies on self-reporting and data quality |
Conclusion
The Higg Index represents a seminal advance in standardizing sustainability measurement for the apparel and footwear industry. Its modular approach—spanning materials, facilities, products, and brands—offers a comprehensive framework to drive performance improvements. Yet its limitations, particularly in coverage, transparency, and public communication, reveal a need for continual refinement.
As the tool evolves with peer-reviewed data, expanded scope, and regulatory alignment, the Higg Index has the potential to solidify its role as a credible metric for sustainability—so long as it remains responsive, transparent, and scientifically rigorous.b
