Make Better Choices at Every Stage of a
Product’s Development

From the materials a designer chooses to feature in your favorite t-shirt to the amount of water used to dye that worn pair of jeans, the Higg Product Tools assess a product’s environmental sustainability impacts. There are two Higg Product Tools: the Higg Materials Sustainability Index (Higg MSI) and the Higg Product Module (Higg PM). These tools empower designers, brands, retailers, and manufacturers, to use life cycle assessment data to make informed decisions to create more sustainable products.

The Higg Materials Sustainability Index

The Higg Materials Sustainability Index (Higg MSI) is the apparel industry’s most trusted tool to measure and score the environmental impacts of materials. Apparel, footwear, and textile industry designers and product developers can use the Higg MSI to assess and compare the crade-to-gate impacts of different materials, such as textiles, plastics, metals, and leather.

The Higg MSI uses data submitted from the industry and life cycle assessment databases to calculate environmental impacts and translate them into comparable Higg MSI scores.

The Higg MSI can calculate the impact of millions of possible material manufacturing variations.

The Higg MSI features 90+ example materials

These examples represent materials commonly used in the industry.









“We use the Higg MSI to understand & measure the environmental impact of Salomon’s materials – we have already scored more than 800 materials so far. The final objective being to score our footwear product and be able to give an environmental visibility to our end consumer and our B2B clients. In addition with the Higg MSI, we can communicate about sustainability transparently with our suppliers and collaborate globally to make more sustainable products.”

Céline Mazars, Material Manager of Footwear, Salomon

“The Higg MSI was developed specially for the textile industry through global industry-wide consensus. Before the Higg MSI, no tool in the apparel industry offered common criteria for life-cycle assessments, methodology, and procedures. We use the Higg MSI to showcase our sustainable materials.”


The Higg Product Module

What’s the global warming potential of your favorite t-shirt? What is the environmental impact of a pair of jeans throughout its full life cycle? The new version of the Higg Product Module (Higg PM) can tell you.

The Higg PM now measures the cradle-to-grave environmental impacts of a product from the point of resource extraction to manufacturing impacts, all the way through product durability, care, and end of use.

The Higg PM is the only tool on the market that can help companies calculate at scale the environmental footprint of their products beyond carbon emissions. Finally, the Higg PM provides credible data that helps companies understand the sustainability performance of their products’ portfolio and enables progress towards circularity goals. The product tool was developed to help companies prepare for anticipated legislation.*

*The Higg PM is designed to evolve and align with anticipated legislation, particularly with upcoming EU PEF Apparel & Footwear methodology.

The Higg Product Module Assesses
5 Environmental Impacts

  • Global Warming Potential
  • Nutrient Pollution in Water (Eutrophication)
  • Water Scarcity
  • Fossil Fuel Depletion
  • Chemistry

For any company planning to track their Scope 3 emissions, Higg MSI and Higg PM would be the best starting point to obtain high-level sources of product level, material level or yarn level emission information. The new Higg PM, now equipped with the cradle to gate data, allows companies to estimate the downstream product use level impacts. MAS uses the Higg PM because of the standardized impact measurements. Standardization will enable direct and faster analysis and help to identify hotspots in products that need further Life Cycle Impact Analysis. With this data, we have started discussions with our customers and supply chain on how to collectively improve product criteria to mitigate climate risk and other environmental impacts. These discussions have enabled us to develop relationships with customers who seek solutions to improve the environmental performance of their product portfolio.

PEARL iZUMi couldn’t be more pleased with the tools and data provided from the Higg Index. The Product Module and the detailed data it delivers inspired our new Pedal to Zero program which allows our customers to do what they love – ride bikes for fun, fitness, transportation and arguably, sanity – and now, also to purposefully offset the environmental impacts of the products they use. By scaling the Product Module, we can achieve our evolving corporate responsibility goals and even enlist our customers to help do the same.

Aldo Apparel

The Higg PM provides granular life cycle assessment data founded in climate science we know we can trust. At ALDO Group, we will use this data to introduce more sustainable materials with a low carbon footprint in our products. We will also use the Higg PM in collaboration with our value chain partners to decarbonize our company’s supply chain.

For Brooks Running, it’s critical that we protect our planet. Our product teams will use the Higg PM to better understand the environmental impacts of our products, and its science-based insight will better position us to strategically create more sustainable options for our customers. This tool will also help the industry compare the sustainability performance of different products, which is a game changer.
