Higg MSI API References


Higg Co provides an application programming interface (API) for the Higg Materials Sustainability Index (MSI). The Higg MSI API can be used by companies to integrate Higg MSI data within their own internal systems. It can also be used by third-parties, such as Product Lifecycle Management (PLM) systems, to enable shared customers to access Higg MSI account data in the third-party system.

Integrating Higg MSI impacts into internal and third-party systems allows designers and sustainability stakeholders to compare material impacts as they make material choices and analyze impacts in their material portfolio.

Higg MSI

The Higg MSI is a material scoring tool that measures the environmental impacts of material production from raw material to the finished processing of the material.

Impacts include both Higg MSI normalized scores and Life Cycle Impact Assessment (LCIA) absolute values. The following impacts are included in the Higg MSI API for all example materials, custom materials, acquired materials, sample trims and components, custom trims and components, sample packaging, and custom packaging:

  • MSI score (sum total of the following impact MSI scores)
  • Global Warming MSI Score
  • Global Warming LCIA value (kg CO2 eq)
  • Eutrophication MSI Score
  • Eutrophication LCIA value (kg PO4– eq)
  • Water Scarcity MSI Score
  • Water Scarcity LCIA value (m3)
  • Abiotic Resource Depletion, Fossil Fuels MSI Score
  • Abiotic Resource Depletion, Fossil Fuels LCIA value (MJ eq)
  • Chemistry MSI Score
  • Chemistry LCIA value (units)
  • Biogenic Carbon Content LCIA value (kg CO2 eq) (Not included in MSI score)
  • Water Consumption LCIA value (liters) (Not included in MSI score)

Each material in Higg MSI is normalized to 1kg.  For example, if a material is 30kg, the Higg MSI impacts can be multiplied by 30 to determine the impact for the completed material.  Trims and Components and Packaging impacts are per unit.

Product Impacts

While Higg MSI tool provides material impacts, it does not provide a means of calculating product impacts.  It is not accurate to sum the impacts for the materials in the product to get a product impact score.  Instead, product impacts are calculated using the Higg Product Module tool.  Materials created in Higg MSI provide the library of materials available in Higg Product Module section Bill of Materials (BoM).

Higg Product Module includes a full analysis of the product inputs and processes to calculate a cradle-to-grave (ie raw material through end of use) product impact assessment.

Higg Product Module is being developed in two phases:

Higg Product Module Phase I will be available mid-Sep 2020.  It includes BoM and finished goods processes.  Higg Product Module Phase I will not have API access at launch.

Higg Product Module Phase II is scheduled for release later Q1 2021 and will add impacts for product distribution, product use, duration of service, and end of life impacts.  An API of the Higg Product Module will be available with launch of Phase II.  Note that Product Module does not include scores and will only have LCIA impacts available.

Use Case

Following is the standard use case for the Higg MSI API v1 released Aug 3, 2020.  The Higg MSI API v1 is a read-only API that sends impact data to a customer internal or third-party system.  If your use case does not fit this example, please contact Higg Co to discuss how we can support your use case and to learn more about the road map for future Higg MSI API functionality.

Customers begin the workflow in the Higg system.  In the Higg MSI tool customers can access the library of example materials and create their own custom materials, trims and components, and packaging.  The customer can also request their suppliers to sign up for a Higg MSI account that allows the supplier to create a limited number of materials for free and share those materials to the customer.

After creating materials in Higg MSI tool, the customer accesses the internal or third-party system where their API account license key has been enabled.  The customer sees in the system a list of the Higg MSI materials which they can then match to the materials in the internal/third-party system.  Once the materials are matched between systems, the Higg MSI impact data is able to flow into the internal/third-party system via the API.

Access Model

Customers can purchase access to the Higg MSI tool either via purchase of SAC Membership (Higg MSI tool is included as part of SAC Membership) or directly purchase Higg MSI tool access from Higg Co. For API access, the customer also purchases an API license key for their account. Third-party developers join the Higg Developer Program.
