Retail–NC-v2009 MRpc79: Material ingredients product manufacturer supply chain optimization

  • Moving LEED's benefits up the supply chain

    Plastic resinPlastic resin – part of the upstream supply chain of many products used in LEED buildings.One of the main reasons USGBC unexpectedly opened a sixth public comment period on LEED version 4 is to gather market feedback on a new option for recognition of sustainability efforts not at the product level, where LEED project teams usually work, but up the supply chain. (See more background in LEEDuser's blog post on this option.)

    “Product Manufacturer Supply Chain Optimization” is a new Option 3 in LEED v4’s Building Product Disclosure and Optimization—Material Ingredients credit. The option is not currently very well-defined, but USGBC has convened a working group to hash out what it might mean in practice, and it has also made it available as a pilot credit to encourage engagement.

    MR Pilot Credit 79: Material ingredients product manufacturer supply chain optimization


    This is a pilot credit. To use any pilot credit on your LEED project, be sure to register here. Documentation requirements and additional questions are listed below.

    To encourage the use of products and materials for which life-cycle information is available and that have environmentally, economically, and socially preferable life-cycle impacts. To reward project teams for selecting products for which the chemical ingredients in the product are inventoried using an accepted methodology and for selecting products verified to minimize the use and generation of harmful substances. To reward raw material manufacturers who produce products verified to have improved life-cycle impacts.


    Product Manufacturer Supply Chain Optimization (1 point)

    Project Team: Use building products that are sourced from product manufacturers who procure raw materials from suppliers meeting criteria below for at least 25%, by cost, of the total value of permanently installed products in the project.

    Manufacturers: Engage in validated and robust safety, health, hazard, and risk programs. Document at least 99% by weight of the ingredients used to make the building product or building material are sourced from companies with independent third party verification of the following along the manufacturer supply chain:

    • Processes are in place to communicate and transparently prioritize chemical ingredients along the supply chain according to available hazard, exposure and use information to identify those that require more detailed evaluation
    • Processes are in place to identify, document, and communicate information on health, safety and environmental characteristics of chemical ingredients
    • Processes are in place to implement measures to manage the health, safety and environmental hazard and risk of chemical ingredients
    • Processes are in place to optimize health, safety and environmental impacts when designing and improving chemical ingredients
    • Processes are in place to communicate, receive and evaluate chemical ingredient safety and stewardship information along the supply chain
    • Safety and stewardship information about the chemical ingredients is publicly available from all points along the supply chain

    For credit achievement calculation, products sourced (extracted, manufactured, and purchased) within 100 miles (160 km) of the project site are valued at 200% of their base contributing cost. For credit achievement calculation, the base contributing cost of individual products compliant with multiple responsible extraction criteria is not permitted to exceed 100% its total actual cost (before regional multipliers) and double counting of single product components compliant with multiple responsible extraction criteria is not permitted and in no case is a product permitted to contribute more than 200% of its total actual cost.

    Structure and enclosure materials may not constitute more than 30% of the value of compliant building products.

    Additional questions
    1. Did your project use the actual or default materials cost to determine the total materials cost?
    2. How did your team determine or estimate the actual materials cost? What method was used?
    3. Where there any challenges in determining the total materials cost? What were they?
    4. If applicable, how would using the actual materials cost verses the default materials cost have effected credit achievement?
