TRACI Impact Assessment Methodology

You can display SolidWorks Sustainability results that are determined using the Tool for the Reduction and Assessment of Chemical and Other Environmental Impacts (TRACI) impact assessment methodology.

Two impact assessment methodologies are available:

  • CML

    This methodology was developed by the Center for Environmental Sciences (CML or Centre for Milieukunde, Leiden) at the University of Leiden, The Netherlands.

    CML is based on European regional conditions. For LCA studies outside of North America, the CML methodology is the most commonly-used set of environmental indicators used for Life Cycle Assessment (LCA).


    This methodology was developed by the United States Environmental Protection Agency.

    TRACI is based on regional conditions of the United States and can be used to accurately model North American LCA studies.

A drop-down list at the bottom of the Environmental Impact section of the Sustainability task pane indicates whether TRACI or CML should be used to calculate results. Use this control to change the impact assessment methodology.
