While LCA is a powerful analytical tool, the information driving LCA-based decisions often fails to adequately address material impacts associated with human health and ecosystem disruption. To address the shortcomings of LCA, the MR section proposes requirements for responsible material sourcing and avoidance of harmful chemicals in building products.
This credit expands on existing credits that deal with material origins (rapidly renewableTerm describing a natural material that is grown and harvested on a relatively short-rotation cycle (defined by the LEED rating system to be ten years or less)., certified woodWood from a source that has been determined, through a certification process, to meet stated ecological and other criteria. There are numerous forest certification programs in general use based on several standards, but only the Forest Stewardship Council's standards, which include requirements that the wood be tracked through its chain-of-custody, can be used to qualify wood for a point in the LEED Rating System., materials reuse) and significantly increases the scope around which credit for responsible sourcing activities will be rewarded. In addition to continuing to support the expansion of responsible forest management activities, the new responsible sourcing credit encourages the expansion of responsible sourcing activity in most industries providing raw materials to the buildings industry.
Submit a list of products purchased contributing toward credit and their corresponding raw material. List the cost and number of items purchased per contributing products and calculate the weighted value according to total weight of materials purchased.

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 verified to have been extracted or sourced in a responsible manner.
Use at least 20 different permanently installed products from at least five different manufacturers that have publicly released a report from their raw material suppliers which include raw material supplier extraction locations, a commitment to long-term ecologically responsible land use, a commitment to reducing environmental harms from extraction and/or manufacturing processes, and a commitment to meeting applicable standards or programs voluntarily that address responsible sourcing criteria.

The homepage for the LEED Pilot Credit Library. The LEED Pilot Credit Library is intended to facilitate the introduction of new prerequisites and credits to LEED. This process will allow USGBC to test and refine credits through LEED 2009 project evaluations before they are sent through the balloting process for introduction into LEED.
Background for the LEED Pilot Credit Library is provided in this foundational document.
I am conducting this survey in affiliation with University of Cincinnati for my Master's thesis in support of my hypothesis. It would just take 10-15 minutes of your time and by completing this survey you would help me in giving my research the required depth in understanding the achievability of the credit points in the Material and Resource category of LEED v2009 and v2013. I will send in the end results of this survey to you, which could potentially make your decision process easier on any future LEED Registered projects you intend to work on.
The following is the link to my survey:
Every response is valuable to my research.Thank you in advance for your time.
It's unclear where GRI-checked reports fall under the credit requirements - would they be considered self-declared for 1/2 value or third-party verified for full value? My guess was self-declared, but perhaps there could be an in-between (3/4 value?) for GRI-checked reports.
Also, for those who haven't used it before, here's a link to the GRI Sustainability Disclosure Database: http://database.globalreporting.org/search
I agree with Christine above; the GRI Sustainability Disclosure Database is very helpful in documenting this credit.
Another good source is the UN Global Compact database: https://www.unglobalcompact.org/what-is-gc/participants
I agree and the link that Christine posted is very useful
In looking for the reports I have found that many of the manufacturers do not have their sustainability reports drafted and are just looking into them - moving to LEED v4 in November and working to obtain the credit is going to be interesting, this will dictate selection of material and require early research. Also I found that many of the manufactures stated that they are looking at updates on a 3 to 4 year cycle and obtaining a current report is going to be difficult.
I recently completed this Pilot Credit and determined that our project meets Option 1 and possibly meets Option 2. My biggest concern with Option 2 is the requirement that structure and enclosure materials may not constitute more than 30% of the value of complaint building products. I am documenting this Pilot Credit for a major renovation LEED 2009 Core & Shell project, so a majority of construction materials are enclosure. Interior finishes make up a very small portion of the overall building; approximately 15%. I think USGBC should consider lifting the 30% requirement for certain project types.
I am working on documentation for this credit but need some advice. In order to document enough raw materials to comply with the final LEED v4 credit wording, some of the raw materials will be petroleum based. Oil is a global commodity. How farFloor-area ratio is the density of nonresidential land use, exclusive of parking, measured as the total nonresidential building floor area divided by the total buildable land area available for nonresidential structures. For example, on a site with 10,000 square feet (930 square meters) of buildable land area, an FAR of 1.0 would be 10,000 square feet (930 square meters) of building floor area. On the same site, an FAR of 1.5 would be 15,000 square feet (1395 square meters), an FAR of 2.0 would be 20,000 square feet (1860 square meters), and an FAR of 0.5 would be 5,000 square feet (465 square meters). up the supply chain do I need to go to collect extraction location and commitment to environmental practices from the supplier?
For example, our carpet uses a coating made from EVA, a copolymer. We can determine where the EVA was manufactured but it's not possible to determine where the ethylene and vinyl acetate were created.
When I go to the current version of the pilot credit form at http://www.usgbc.org/ShowFile.aspx?DocumentID=10106 there is no actual Material Source Disclosure language within the credit itself. However, the narrative after indicates that you probably need to get suppliers to interact with GRI? The language on the form also does not match the language on this page.
Also, the form now includes the language: "Materials meeting applicable criteria below plus extracted and manufactured do-mestically are valued at 1.5 times the material cost, or regionally (within the state, province, or territory) at twice the material cost. Products and materials extracted and manufactured locally (within 50 miles or 80 km), are valued at three times the material cost. If project is located in the United States or Canada, products and materials meeting local criteria automatically qualify for this credit."
Does this mean that there are no reporting or public disclosure requirements on the manufacturer in the U.S. and Canada? If it does not, what is the intent of that last sentence?
If products have a % of recycled content which is assessed under MRc4 does this mean that the whole product is excluded from these calculations or just the portion which has the recycled content?
Vivien, I'm confused—what are you seeing as the relation between this credit and MRc4?
